Course Description

BEST in Class course for programmers to learn multitasking, MultiThreading and Parallel programming paradigm.

Objective :

Computers can execute more than one statements at a time this is called parallel processing. These days when there are multi core processors are easily available programmers should defiantly take advantage of parallel programming for scalable and highly performing and responsive application. This is only possible using Multi Threading programming.

Multi threading programming comes with certain complexities and sometimes difficult to program. This objective of this course is make to enable -

  1. Basic Multi Threading

  2. Advanced Multi threading

  3. Multi Processing

  4. Concurrent Collections

  5. Parallel algorithms.

  6. Asynchronous Programming using Completed Future

  7. Parallel Streams for Faster processing of Collections.

If you are able to learn these concepts - you will be able to create applications, ready to scale and highly responsive.


We will start from very basics and will deep dive into the very advanced concepts.

We will start from basics by understanding -

Introduction To Multitasking and Multihreading

Creating Thread and Understanding Its Life

Threading API

Then we will move further to challenges associated with -

Concurrency Challenges

Concurrency Challenges &  Race Conditions

Further we will discuss into solutions to the challenges

Achieving Mutual Exclusion or Solving he challenges

Liveness Problems

The we will move into some related concepts

Daemon Threads

Further in the discussion we will move to some advanced concepts related to MultiThreading -

Advanced Multithreading

             Thread Groups

             Thread Pool and Executors

             Thread Local

              Callable and Future

The we will discuss Concurrent Collections and Concurrent Utilities

            Need of Concurrent Collections

            Concurrent Modification Exception

            How Concurrent Collection Solved the problems

            ConncurentHashMap Hierarchy and Methods

            ConncurentHashMap internal Implementation

            ConncurentHashMap in Multithreading Environment Program Demo

            CopyonWrite ArrayList

            CopyOnWriteArrayList - Constructors and Methods

            CopyOnWriteArraySet

            Count Down Lache

            Cyclic Barrier

            Blocking Queue

             Exchangers

             Semphores

Then  we will write and solve some Algorithms using parallel processing

             Multi Processing and Parrlel Comutin Algorithums

             Implementing a Multithreading Chat Serer

We will also Discuss CompletableFuture is used for asynchronous programming in Java.


Hope you will enjoy the journey - please don't forgot to ask questions in Q&A and we will respond as quickly as possible.

Last but not least - you got an option to return back the course within 30 days it you find it does not fulfill your needs

See you in the Course and Happy Learning

Lengthy course, yet if you are serious about learning, it's a course that has left nothing untaught in the space of multi-threading in Java. Very detailed, well-structured, never getting bored. I'm binge watching it to learn many things I never knew until now. One feedback is that it would be great if the entire course could be made more practical/engaging by teaching the same projects via a mini project, that way it helps the students to gain an insight into the practical situation where the concepts can be applied. BTW, I'm currently an SDE at Amazon.

I liked the explanations very much. I am just not giving a 5 because think she could just copy/paste existing methods that are similar, instead of writing again from scratch. Also, I found some tests a little confusing.

The course only contain 3 hours worth of content. Rest of the time we are waiting for the instructor to write the code with slow typing speed and fixing typos.

very very very good course for Multi-Threading concepts and practical approaches...by taking this course I overcame the fear of Threads and found this one of the most interesting concepts in Java...thanks for creating such a wonderful course!!!

Excellent. Perfect. Like usual. Complete. Pedagogical too. I love this course. Greetings from France.

Audio quality is very poor in some videos. Especially in sleep() method video, could not hear anything. Without headphones, couldn't hear. Instructor is very lazy to type something. Keeps editing on previously copied statements and wasting time for editing those statements. Makes me feel like sitting on NPTEL classes.

pros 1. Course is good for beginner 2. author examples are good 3. appendix section is great 4. topic coverage is good cons 1. u need to play video in speed 1:25 else it will look like slow motion. I think they intentionally increase the length of course. 2. code samples and PPTs should be on GitHub or bitbuket or dirve. 3. algorithms sections should be better. :)

Very Detailed Course, Good Content. Although, it takes some time to complete a course like this long. But Its good that you can find everything in one place for one Topic. Thank you for putting the efforts.

By Nupur on 10/4/2019

The content of this course is exceptionally interesting and easy to understand. I found this course very well structured which helped me overcome my fear of difficult topics. This course gives me a very clear understanding about Multithreading so I like to go through again and again. Good Job!

By Sonal on 8/23/2019

This is an Excellent Course on Multithreading, detailed and clear explanation on basic to advance multithreading.
