Creating Multiple Threads In Java

Previously we have discussed about

Choosing Best Approach Among Implementing Runnable Interface or entends Thread Class.

Till now we have been using only two threads: the main thread and one child thread.

We can use as many threads as we want, But now we are using three threads in below example.

Example of Creating Multiple Threads:

class NewThread implements Runnable{

String name;

Thread t;

public NewThread(String threadName) {

name = threadName;

t = new Thread(this,name);

}

@Override

public void run() {

try {

for(int i=0;i<5;i++){

System.out.println(name+" : "+i);

Thread.sleep(1000);

}

} catch (Exception e) {

e.printStackTrace();

}

System.out.println(name +" Exit.");

}

}

public class Test {

public static void main(String[] args) {

NewThread t = new NewThread("One");

NewThread t1 = new NewThread("Two");

NewThread t2 = new NewThread("Three");

t.run();

t1.run();

t2.run();

try {

Thread.sleep(10000);

} catch (Exception e) {

e.printStackTrace();

}

System.out.println("Main thread exiting.");

}

}

Program Output:

One : 0
One : 1
One : 2
One : 3
One : 4
One Exit.
Two : 0
Two : 1
Two : 2
Two : 3
Two : 4
Two Exit.
Three : 0
Three : 1
Three : 2
Three : 3
Three : 4
Three Exit.
Main thread exiting.
