Java Concurrency Tutorial

Java concurrency is an essential topic in Java programming. It deals with the execution of multiple threads simultaneously within a single process. This tutorial will help you understand the basics of Java concurrency, including thread creation, synchronization, and concurrent programming patterns.

Thread Creation

In Java, there are two ways to create a new thread:

1. Extending the Thread class: This is the traditional way to create a thread in Java.
2. Implementing the Runnable interface: This is a more flexible and recommended approach.

Here is an example of extending the Thread class:

public class MyThread extends Thread {
    @Override
    public void run() {
        // Code to be executed in the thread
    }
}

And here is an example of implementing the Runnable interface:

public class MyRunnable implements Runnable {
    @Override
    public void run() {
        // Code to be executed in the thread
    }
}

Synchronization

Synchronization is used to control access to shared resources by multiple threads. It ensures that only one thread can access a shared resource at a time.

Here is an example of synchronized method:

public class Counter {
    private int count = 0;

    public synchronized void increment() {
        count++;
    }
}

Concurrent Programming Patterns

Java provides several concurrent programming patterns, such as:

• Executor Framework: This framework simplifies the execution of asynchronous tasks.
• Concurrent Collections: These are thread-safe collections provided by the Java Collections Framework.
• Atomic Variables: These are variables that provide atomic operations on single variables.
