Multi-Threading in Java

Multithreading in Java refers to the concurrent execution of multiple threads within a Java program. A thread is the smallest unit of a program that can be executed independently, and multithreading allows you to write programs that can perform multiple tasks simultaneously. Java provides built-in support for multithreading through its java.lang.Thread class and the java.lang.Runnable interface.

Here are some key concepts related to multithreading in Java:

• Thread Class: In Java, you can create and manage threads using the Thread class. You can create a new thread by extending the Thread class and overriding its run() method, which contains the code that will be executed in the new thread.

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

• Runnable Interface: An alternative way to create threads in Java is by implementing the Runnable interface. This interface defines a single run() method, and you can pass a Runnable object to a Thread constructor.

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

// Create a thread using a Runnable
Runnable myRunnable = new MyRunnable();
Thread thread = new Thread(myRunnable);

• Thread Lifecycle: A thread goes…
