Fresh Content

Owners of Java ( Oracles ) are releasing new versions of Java at least twice a year and it’s no secret how technology is advancing at a rapid rate. It’s crucial to stay on top of the latest knowledge. With this course, you will always have a chance to follow the latest trends.

What is Java?

Java is a programming language and platform initially developed by Sun Microsystems and now owned by Oracle. Java is inspired by C and C++ and uses an object-oriented programming model, which means that concepts or things are represented as “objects” that have data fields and methods. One of the biggest advantages of Java is that it runs on a Java Virtual Machine (JVM), meaning that you can execute Java code on any platform that has a JVM, without re-compilation. This is different from C and C++, which require re-compilation for every hardware platform you execute the code on. Java has many other advantages, including automatic memory management. This eliminates hard-to-understand pointers used in languages like C, which can help Java developers write better code in a shorter period of time.

What does it mean that Java is an object-oriented programming language?

Java is an object-oriented programming (OOP) language, which means concepts or things are represented as “objects” that have data fields and methods. In object-oriented programming, models called “objects” represent either a programming entity or an abstract concept. These objects are created and assembled independently of one another but can work with each other in logical ways. Objects are manifestations of classes and can inherit code allowing for code re-use, which can drastically reduce code duplication if used correctly. Additionally, encapsulation, another core OOP concept, allows you to create code with the implementation hidden. Although, in many cases, writing OOP code in Java (and other OOP languages) can take longer than using a procedural language, the benefits obtained with OOP, namely code reusability, encapsulation of data, and readability of code, often result in code that is easier to maintain in the long run.

What is Java used for?

Java is a very versatile language. Several fields use Java, including Android app development, desktop applications that work on many operating systems, server-side applications, and more. The virtual machine required to run Java programs has been ported to numerous operating systems allowing Java to run on virtually all hardware. According to the TIOBE index, Java has consistently been in the top 3 most-used and popular languages since its initial release in the 1990s. Many developers still consider Java the language of choice in areas such as enterprise and application servers, and even in embedded systems development. Many Fortune 500 companies rely on Java to run their core systems and employers often view Java experience on a résumé as favorable due to its popularity.

What certification is best for Java?

Oracle, the owner of the Java programming language, has the Oracle Certified Developer: Java SE 11 Developer program, which is easily the best certification to obtain for Java developers. The main reason why it’s the best certification, is, unlike most other certifications for Java, the Oracle certification is both well known and universally accepted by employers all over the world. The exam is challenging. You also must bring an ID with you to the exam, so you cannot get anyone to take it for you. Certification is really valuable for both the certification holder and for future employers. There are few, if any, other certification programs so universally accepted as Oracle’s Java certification. Thus, getting Java certification is one of the surest ways to give yourself an advantage over other job seekers in the marketplace.

Filling in the blanks, provides a great foundation for concepts I know, and others I need to strengthen. Eclipse ide examples are great as well. Very happy I have enrolled for this course. Instructor is clear, explains concepts well, uses great demos, and cracks the odd funny comment now and then just to make sure we are paying attention lol. :)

By Aishwarya Saxena on 3/26/2024

SIr you have explained really well, the concepts covered and were explained in a very effective way. It helped me alot in clearing my concept. Thank You! please make more courses, with this kind of detailed explainations and concepts. Thanks again

By Yaseen Hassan on 10/26/2023

While going through this course, there's no thorough explanation on a lot of the topics/study material. He is just talking through the steps while he codes. We need to be able to understand in depth why and what you are writing. At times left very frustrated with what im watching while hes just going through the motions.

By Amarilys Otero Ayala on 7/7/2023

Excellent course! I really love the explanation of handling exceptions. Is a good course for refreshing some concepts and also for those who are new to Java.

By Ryan Pochmara on 8/24/2022

This course covered what I needed at a great pace. You are able to jump right in, but not too fast that you miss any of the presented concepts. The exercises presented are clear and non-confusing. There is no trip-ups or gotchas in the course which is in my opinion for an introductory course is great. This is the first Udemy course I was able to complete because of the easiness of it. Thank You, and on to my future in Java programming!

By Sing Ho Joseph Chan on 8/26/2021

The important reason I choose this course is the clear English speaker as instructor. This course is well organised for entry level programmer or a refresher for programming enthusiast. I recommend this course if you are new to programming, but you need to enrol in a higher level course before you can have sufficient knowledge to write real life applications.

By Travis Elsberry on 7/18/2021

Course basically gave a good, lightweight overview of Java along with some examples to aid in understanding the material. Not super in-depth but enough to be dangerous with it.

By Stiorra Z. on 9/6/2020

This is really for beginners level but I think it would be good if more explanation is given because for total beginners it can be not easy to understand well. One thing I like is the shortcuts he taught in the lessons.

By Iqra Khatoon on 6/9/2020

I really have enjoyed learning with Scratch.I was here to garnish my skills of developing in java and I am confident that I really have acheived the same. Thanks!!

By Mduduzi Phakathi on 5/12/2020

A bit slow but I suppose the lecturer is trying to accomodate aspiring java developers. The enum part I did not get. The Arrays,Lists, ArrayList, etc were not done any justice. It is a beginner course and opened my eyes to things you used but generally never bothered to ask why.

still in the beginning so I can't put much commend in here, but so far the explanation was really easy to understand i think

This class is excellent to learn the basics of JAVA in detail.
It gives you a very reasonable understanding of JAVA.
Instructor makes it very easy to follow his well-designed lectures, real life projects and code examples.
Thanks your hard work.
