This list is for anyone learning Java, from a first program to Spring Boot microservices and test automation. Our catalogue lists 310 live Udemy courses in Java and the Spring framework. These ten are the ones we would buy at each step. They have over 670,000 student reviews between them, every one is rated 4.5 or higher, and nine of them were updated in 2026.
Every rating, review count, length and last-update date on this page comes from our catalogue and is refreshed with it. The pros and cons are written by CourseDuck’s editors from the course syllabus and a sample of the written student reviews, and checked against both; no course pays to be on this list. Udemy prices move with its sales, so treat the price on each card as the current one, not a fixed one.
How to pick

Start here: core Java
1. Java Masterclass 2025: 130+ Hours of Expert Lessons
Tim Buchalka’s Masterclass is the most-reviewed Java course in our catalogue, with about 215,000 reviews and roughly 966,000 students. It is also enormous: 136 hours over 739 lectures, from JShell and IntelliJ setup through OOP, generics, lambdas, collections, streams, file I/O and a short concurrency section, with 50 coding exercises and 50 quizzes. It was updated in August 2026. Reviewers praise the depth, and experienced developers say they still learned things from it. The complaints are consistent: examples that pile up four or five classes where a simple snippet would do, code pasted onto the screen rather than typed live, and a commitment measured in months. Pick it if you want one course to carry you from zero to solid core Java.
Pros
- Covers core Java end to end: OOP, generics, lambdas, collections, streams, file I/O and concurrency in 21 sections
- 50 coding exercises and 50 quizzes, plus source code attached to every video, which beginners call guard rails
- Updated in August 2026 and refreshed steadily since 2015, so the Java 17 material is current
- Experienced developers in the reviews say they still picked up new things from it
Cons
- Low-star reviews say examples are overcomplicated, with several classes introduced at once instead of simple demos
- Code is pasted onto the screen rather than typed live, and some find the newer videos rushed and monotone
- At 136 hours it is a months-long commitment, and course files arrive as many separate zips
What students say
Shlomi KikoAs an experienced developer and data engineer, i can really say it's one of the best courses i've seen. I've personally learned a lot.
Fatma ZemannIch hatte anfangs Sorge ob ich einem englischsprachigen Kurs folgen kann, aber die Entscheidung hat sich für mich ausgezahlt, Herr Buchalka weiß wirklich sehr viel und fordert einen richtig. Nach den Algorithmusaufgaben dampft einem erstmal der Kopf. OOP habe ich mit seiner Hilfe etwas besser verstanden, er hat sehr viel Arbeit in diesen Kurs gesteckt, der wurde mir zurecht als Goldstandard...

2. Java Programming for Complete Beginners
Ranga Karanam’s in28Minutes course is the type-along alternative for people who have never coded. It starts in JShell with a multiplication table, moves to Eclipse, then covers object-oriented programming, arrays, collections, generics and functional programming: about 60 hours over 732 lectures, with 67 quizzes and 46 coding exercises. It was updated in May 2026 and has about 54,000 reviews at 4.6. Reviewers praise the small lectures and plain explanations, and one says it feels like an actual classroom. One student wanted the exercise test cases visible so they could see where a solution went wrong, and a one-star review says some sections pack in a lot without enough depth.
Pros
- Short lectures and plain explanations that reviewers call easy to follow for people with no background
- 46 coding exercises and 67 quizzes, with an exercise set after most topics
- Starts in JShell, so beginners see results before setting up a full project
Cons
- Around 60 hours is a long commitment for a first programming language
- One reviewer could not tell where a coding exercise went wrong because the test cases are hidden
- A one-star review says some sections pack in a lot of information without enough depth
What students say
Patricio AgurtoThis was an amazing match for my career development. I will continue learning Java until I become a senior backend developer.
Mahalakshmi SusarlaAwesome explanation. Got clarity on many areas. Please create more videos on technologies like Kafka in depth.

3. Learn JAVA Programming - Beginner to Master
Abdul Bari’s course suits people who have programmed a little before and want every core Java topic explained slowly and in order. It runs 61 hours over 333 lectures, from variables and operators through OOP, multithreading and collections to JDBC, networking, Swing and JavaFX. It was updated in May 2026 and has about 31,000 reviews at 4.7. Reviewers say dense topics are broken into small, plain-language pieces, and one says ideas that felt intimidating elsewhere finally clicked here. Practice is light, with 10 coding exercises and no projects, and one reviewer wanted command line steps for Mac users.
Pros
- Abdul Bari breaks down multithreading, collections and OOP into small, clear steps
- Covers topics many Udemy Java courses skip: AWT, Swing, JavaFX, and JDBC with SQLite
- Updated as recently as May 2026
Cons
- Only 10 coding exercises and no projects, so practice is light relative to the lecture count
- At 61 hours it moves slowly, better for steady study than a fast start
- A few reviewers wanted deeper linked list coverage, Mac terminal steps, or Spring Boot content
What students say
Prince Rathorethe we he teach is outstanding , if you buy this course you don't have to go for any other course for java
jaswanth ambativery clean explanation and good teaching but tell the commands using in command prompts for Mac using students also

4. The Complete Java Certification Course
If you want a credential at the end, Job Ready Programmer’s course leads toward Oracle’s OCAJP 1Z0-808 exam. It is shorter, about 18 hours, and covers syntax, object orientation, collections, generics, concurrency and JDBC, with 47 quizzes, 45 coding exercises and three practical projects: a car dealership system, a stock market data processor and a data analytics tool. It was last updated in November 2025 and has about 30,500 reviews at 4.7. Reviewers credit instructor Imtiaz Ahmed’s step-by-step explanations, especially of object orientation. A few coding exercise solutions have typos, lecture code is not easy to download, and lambdas and file handling get less depth than the basics.
Pros
- Three industry-style projects instead of a game clone
- Heavy focus on object orientation, which reviewers single out
- Concurrency gets real depth, 157 minutes across seven lectures
Cons
- A few coding exercise solutions have typos that keep the code from running, per reviews
- One reviewer found the lesson length confusing to follow as a beginner
- Lecture code isn’t easy to download, so reviewing past videos means scrubbing footage
What students say
Vaishali kandekarI’ve found this course incredibly helpful for revisiting Java basics. The instructor, Imtiaz Ahmed, explains everything in a detailed yet simple way, Even though I already have some experience with Java, this course refined my knowledge in a way I couldn’t have anticipated. If you prefer learning through visuals, this course is a great way to speed up your understanding without wasting time.
Vishal AbrolI liked the way the instructor takes the students on a virtual journey where connecting dots from the previous lectures at every possible point and incrementally adding value and new knowledge points at every stage. Even my 9 yr old is able to understand the basics of it and for me because I have prior knowledge of Java - even I felt its worth the value to invest in this course - It surely added...

Catch up on modern Java
5. Modern Java: Mastering Features from Java 8 to Java 25
If you learned Java years ago, this course from Pragmatic Code School is the catch-up. It starts with the Java 8 functional features (lambdas, streams, Optional and the date and time API), then moves to var, text blocks, records, sealed classes, pattern matching, Stream Gatherers, the HTTP client and modules, with Java 25 material in its March 2026 update. It runs 15.8 hours over 147 lectures and has about 15,600 reviews at 4.5. Reviewers like the many small examples and single out the streams sections. Experienced developers say simple topics get stretched over several lessons, and there are no quizzes or coding exercises, so if you already use streams, skim the first half and jump to the newer features.
Pros
- Many short, simple code examples that reviewers say stick through repetition
- Streams sections are praised as helpful, within a logical order of topics
- Covers Java 8 through 25, including records, sealed classes and Gatherers
- Last updated in March 2026, with Java 25 material included
Cons
- Experienced developers say simple topics are stretched over several long lessons
- Sound is uneven, and a few examples need updating for newer Java versions
- Windows and IntelliJ setup is rushed, and some code goes unexplained
What students say
Daljeet Harshif you go through this complete tutorial then you do not need to go anywhere. most of the concept is covered here.
Sergio Alberto Jaramillo OrozcoThe examples meet the most important topic in the last few releases. I think the instructor was able to explain all in a good way. His English level is really nice and the concepts really were clear. Thanks!

6. Java Multithreading, Concurrency & Performance Optimization
Michael Pogrebinsky’s course is a short, focused tour of Java concurrency: 5.4 hours over 40 lectures, from how threads work through performance, locks, inter-thread communication and lock-free data structures, ending with virtual threads and high-performance IO. It was refreshed in September 2026, has about 14,800 reviews at 4.6, and adds 21 quizzes and 5 coding exercises. Reviewers say the animations and realistic examples make a scary topic click. It skips detail on ConcurrentHashMap and CompletableFuture, and the image and matrix processing examples can bury the concept for some students.
Pros
- Animations and real-world examples make a hard topic easier to follow, reviewers say
- Covers virtual threads and high-performance IO, and was updated in September 2026
- Short and to the point at 5.4 hours, with 21 quizzes and 5 coding exercises
- Builds step by step from thread basics up to lock-free data structures
Cons
- Skips detail on ConcurrentHashMap and CompletableFuture, reviewers say
- Image and matrix processing examples can bury the concept for some students
- Some examples are hard to follow; one reviewer rewatched videos, another found the pace too fast
What students say
Maria BoikoThis couse offers an excellent breakdown of multithreading fundamentals, making complex concurrency teories easy to grasp. It does a good job of structuring the existing knowledge while filling in critical gaps.
Anonymized UserWhile explaining or writing a code please provide some highlighting arrows, so that it will be more clear to catch what is happening, rather than rewinding the course multiple times. Thanks this course was really helpful.

Data structures and interviews
7. Java Data Structures & Algorithms + LEETCODE Exercises
Scott Barrett’s course teaches data structures and algorithms in Java with animations that draw out every step. It runs 11.1 hours over 150 lectures with 105 coding exercises and 112 quizzes, covering Big O, linked lists, stacks and queues, trees, hash tables, graphs, heaps, recursion, sorting and a short dynamic programming section. It was updated in April 2026 and has about 14,800 reviews at 4.6. Reviewers keep coming back to the visuals. Treat it as a fundamentals course with some interview flavour: the LeetCode walkthroughs cluster around linked lists, stacks and queues and hash tables, with none for graphs or heaps.
Pros
- Animated walkthroughs make data structures easy to picture, which reviewers mention again and again
- 105 coding exercises and 112 quizzes let students practice right after each topic
- Short lectures and 11.1 hours total, so the whole course is quick to finish
Cons
- LeetCode walkthroughs are concentrated in linked lists and hash tables, with none for graphs or heaps
- Some complex steps are skipped, so a reviewer needed outside help to follow
- Array and string techniques are thin, and basic Java is assumed from the start
What students say
Emilio Alfredo Perez VillaGreat course for people who didnt pay attenttion to the data structure class , and also those who werent taught about linkedlist and binary trees , the course makes clear the differences between value types and reference types , and the graphic explanations are just amazing, worth taking it
MasudExcellent course! The lessons were clear, engaging, and very informative. The instructor was knowledgeable and supportive, making even difficult topics easy to understand. I learned a lot and feel much more confident in my skills. I would highly recommend this course to other students looking for a high-quality learning experience.

Spring Boot and microservices
8. Spring Boot 4, Spring 7 & Hibernate for Beginners
Chad Darby’s course is the most-reviewed Spring course in our catalogue, with about 95,000 reviews and 466,000 students, and it was updated in July 2026 for Spring Boot 4 and Spring 7. Over roughly 35 hours and 419 lectures you type along through REST CRUD APIs, REST and MVC security, Spring Data JPA, Thymeleaf, advanced JPA mappings and AOP, all wired to MySQL. It assumes basic Java. Reviewers praise short videos that explain one idea and then code it, and several call it the best Spring course they have taken. The pace is slow and repetitive, with whole projects retyped when a section builds on earlier code, and there are no quizzes or coding exercises.
Pros
- Updated July 2026 for Spring Boot 4 and Spring 7, so the code matches current releases
- Short videos that explain one idea and then code it, which reviewers say keeps 35 hours from feeling daunting
- Type-along projects across REST, Spring Data JPA, Spring Data REST, MVC and security
Cons
- Slow and repetitive pace; one reviewer skipped more than half of it, and projects get retyped from scratch
- Broad rather than deep, with no quizzes or coding exercises to test yourself
- One reviewer objected to plaintext database passwords being shown at all
What students say
Aman GuptaAs I am learning first time spring boot and this covers the basics what is must required and got to knows about annotations.This will beginning of my knowledege in Backened. I want that instructor should covers more topics such Microservices, System Design.As How to make distributed and scalale real time systems.
William OwenMr. Darby has gone above and beyond to put this course together. I'm really glad to have him as an online instructor. He packs a lot of material in and does so in a controlled manner that is easy to follow. He has updated his videos in response from students, which shows that he is a real and welcoming online presence.

9. Master Microservices with Spring Boot and Spring Cloud
Once Spring Boot makes sense, Ranga Karanam’s microservices course is the natural next step. The first half builds a REST API with Spring Boot (versioning, validation, HATEOAS, OpenAPI docs and basic security); the second moves into Spring Cloud (a config server, Eureka, an API gateway, Resilience4J and Zipkin tracing), then Docker and Kubernetes. It runs 22.8 hours over 286 lectures, was updated in May 2026 and has about 60,500 reviews at 4.5. Reviewers say even the Kubernetes lessons are easy to follow and the practicals just work. There are no quizzes or exercises, one reviewer missed a big-picture architecture diagram, and low-star reviews mention plugs for other in28Minutes courses.
Pros
- One reviewer says the practicals never got stuck; another found even the Kubernetes lessons easy to follow
- Appendices cover Spring, Spring Boot, JPA, JUnit, Mockito and Gradle for anyone with gaps
- Updated May 2026, with V3 Docker and Kubernetes sections
Cons
- One student finds the accent hard to follow, and another found Japanese subtitles stop after section 5
- No big-picture architecture diagram, so one reviewer says they lose track of where the project is heading
- No quizzes or coding exercises, and low-star reviews mention plugs for other in28Minutes courses
What students say
Anonymized UserRanga Karanam is one of the guys who breaks down the complex topics and explains in way easy to understand. The teaching and clarity of the topics is simply outstanding.
Aditi BhangaleTopics are made simple, easy and crisp to understand. He has guided us properly through the practicals. We don't get stuck anywhere while executing the praticals. Hence, I loved the way he is teaching.

Test automation
10. Selenium WebDriver with Java -Basics to Advanced+Frameworks
For manual testers moving into automation, Rahul Shetty’s Selenium course is the big one: about 141,700 reviews at 4.6 and roughly 471,000 students. It assumes no Java and teaches it along the way, then covers locators, waits and Selenium 4 features before a full framework build with TestNG, Maven, Page Object, Extent reports, Jenkins and Cucumber. It runs 56 hours over 339 lectures and was updated in July 2026. Reviewers say concepts are explained step by step so non-coders can follow, and that the trainer team answers questions quickly. Nearly everything is built inside one project, and the core Java tutorials sit at the end of the syllabus, so beginners should watch those first.
Pros
- No Java assumed; a reviewer with no prior Java says he followed along and learned it here
- Full framework build: TestNG, Maven, Page Object, Extent reports, Jenkins, Cucumber, Grid and Git
- Assignments after most modules and a trainer team that reviewers say answers questions quickly
- Updated July 2026; covers Selenium 4 features, Chrome DevTools Protocol and a GitHub Copilot lecture
Cons
- Nearly everything is built inside one project; a one-star reviewer wanted a second full build to practice on
- 56 hours long, and the core Java tutorials sit at the end of the syllabus instead of the start
- One reviewer found the practice site for network mocking offline, and the description is heavy on sales talk
What students say
Uday MehrotraThis is a very well-structured and comprehensive course on Selenium WebDriver with Java. It covers everything from basics to advanced concepts, including TestNG, framework design (POM), data-driven testing, and Selenium DevTools.
