Java Multithreading Demystified: Code Examples and Concepts

Multithreading in Java allows multiple threads to execute concurrently. This improves application performance. A thread is a lightweight process, and Java provides the Thread class and Runnable interface to implement multithreading. Each thread runs independently but shares the same memory.

Here’s an example of creating a thread using the Runnable interface:

class MyThread implements Runnable {
    public void run() {
        System.out.println("Thread is running");
    }
}

public class Test {
    public static void main(String[] args) {
        Thread t = new Thread(new MyThread());
        t.start();
    }
}
            

In this example, the `run()` method contains the code executed by the thread. Java also supports thread synchronization to avoid race conditions when multiple threads access shared resources. Use `synchronized` to control thread access to shared blocks of code or methods. Understanding multithreading is crucial for writing efficient Java applications.
