Write a program in java for creating multiple threads?

Answer 1

class NewThread implements Runnable { String name; Thread t; NewThread(String threadname) { name=threadname; t=new Thread(this,name); System.out.println("New Thread:"+t); t.start(); } public void run() { try { for(int i=5;i>0;i--) { System.out.println(name+ ":"+i); Thread.sleep(1000); } } catch(InterruptedException e) { System.out.println(name+" Interrupted"); } System.out.println(name+" exiting"); } } class MultiThreadDemo { public staticvoid main(String[] args) { new NewThread("One"); new NewThread("Two"); new NewThread("Three"); try { Thread.sleep(10000); } catch(InterruptedException e) { System.out.println("Main Thread Interrupted"); } System.out.println("Main Thread Exiting"); } }

Output:

New Thread :Thread[One,5,main]

New Thread : Thread[Two,5,main]

One:5

Two:5

New Thread : Thread[Three,5,main]

Three:5

One:4

Three:4

Two:4

One:3

Three:3

Two:3

One:2

Three:2

Two:2

One:1

Three:1

Two:1

One exiting

Three exiting

Two exiting

Main Thread Exiting
