    In this video, we will introduce the course and discuss what you will learn about multithreading in Java.


    What is Java multithreading and why is it important?

    Java multithreading allows a program to execute multiple threads concurrently, improving performance and responsiveness. It is essential for applications requiring parallel processing or handling multiple tasks simultaneously.

    What is the difference between a thread and a process in Java?

    A thread is a lightweight unit of execution within a process. Multiple threads share the same memory space of a process, making communication easier and resource usage more efficient compared to multiple processes.

Requirements

  • No prior knowledge is required about Java Multithreading
  • Basic Java skills are required
  • A computer with a 64-bit operating system
  • We preferred MacOS (64-bit) but this is not mandatory. You can prefer to use other Operating Systems.
  • We preferred IntelliJ which is a powerful and advanced text editor with a lot of plug-ins and tools
  • Nothing else! It’s just you, your computer, and your ambition to get started today

Description

Hello there,

Welcome to the "Java Multithreading and Concurrency from Basics to Advanced" course.

Java Multithreading, Java Concurrency and Parallelism with real-world projects, best practices and performance tuning


Multithreading is an essential concept in modern programming, enabling applications to execute multiple tasks simultaneously. Java provides robust multithreading capabilities, allowing developers to write efficient, responsive, and scalable software. Whether you are developing backend systems, real-time applications, or high-performance computing solutions, mastering multithreading will elevate your Java programming skills to the next level. So with this course, learn how to leverage Java’s powerful multithreading and concurrency features to build scalable, high-performance applications.


In this course, we aim to help you understand Java’s multithreading model and concurrency utilities so you can write thread-safe and efficient applications.


Today’s applications require high performance and responsiveness. Whether you are working with large-scale enterprise applications, financial systems, or real-time messaging applications, understanding threads, synchronization, and concurrent programming is critical.


Also, this course is project-based and we will do more than 20 coding exercises.


In this course you will learn;

  • Introduction to threads and multithreading

  • Thread creation using Thread and Runnable

  • Thread management and lifecycle

  • Synchronization techniques (synchronized, volatile, Lock API)

  • Advanced locking mechanisms (ReentrantLock, ReadWriteLock)

  • Java’s high-level concurrency APIs (ExecutorService, Future, Callable)

  • Thread coordination (wait(), notify(), condition variables)

  • Working with thread-safe collections and blocking queues

  • Performance optimization, avoiding deadlocks, and scaling applications

  • Real-world multithreading case studies (Web server, Producer-Consumer, Chat system)

With multithreading, you can:
- Improve application performance by utilizing multiple CPU cores
- Build responsive applications that don’t freeze during long-running tasks
- Ensure thread safety and prevent issues like race conditions and deadlocks
- Master Java’s high-level concurrency APIs and parallel computing techniques



What is Multithreading in Java?

Multithreading in Java is an act of executing a complex process using virtual processing entities independent of each other. These entities are called threads. Threads in Java are virtual and share the same memory location of the process. As the threads are virtual, they exhibit a safer way of executing a process.


What is a Thread in Java?

A thread is the smallest segment of an entire process. A thread is an independent, virtual and sequential control flow within a process. In process execution, it involves a collection of threads, and each thread shares the same memory. Each thread performs the job independently of another thread.


Multithreading vs. multitasking vs. multiprocessing

Multithreading differs from Multitasking and multiprocessing. However, multitasking and multiprocessing are related to multithreading in the following ways:

  • Multitasking is a computer's ability to execute two or more concurrent programs. Multithreading makes multitasking possible when it breaks programs into smaller, executable threads. Each thread has the programming elements needed to execute the main program, and the computer executes each thread one at a time.

  • Multiprocessing uses more than one CPU to speed up overall processing and supports multitasking.
