Define the concepts of threads.

Answer 1

The Java language includes a powerful threading facility built into the language. You can use

the threading facility to:

· Increase the responsiveness of GUI applications

· Take advantage of multiprocessor systems

· Simplify program logic when there are multiple independent entities

· Perform blocking I/O without blocking the entire program

You can create Threads in Java using two ways - Implementing the Runnable Interface or by Extending the Thread class

A Sample Thread program:

public class TwoThreads {

public static class Thread1 extends Thread {

public void run() {

System.out.println("A");

System.out.println("B");

}

}

public static class Thread2 extends Thread {

public void run() {

System.out.println("1");

System.out.println("2");

}

}

public static void main(String[] args) {

new Thread1().start();

new Thread2().start();

}

}
