In this article we will learn to implement a Java program to demonstrate life cycle of a thread. A Java program is provided below to illustrate life cycle of a thread.

 

Program is as follows:

import java.util.*;
class ChildThread implements Runnable
{
	Thread t;
	ChildThread()
	{
		t = new Thread(this);
		System.out.println("Thread is in new state");
		t.start();
	}
	public void run()
	{
		System.out.println("Thread is in runnable state");
		Scanner s = new Scanner(System.in);
		System.out.println("Thread entering blocked state");
		System.out.print("Enter a string: ");
		String str = s.next();
		for(int i = 1; i <= 3; i++)
		{
			try
			{
				System.out.println("Thread suspended");
				t.sleep(1000);
				System.out.println("Thread is running");
			}
			catch(InterruptedException e)
			{
				System.out.println("Thread interrupted");
			}
			System.out.println("Thread terminated");
			t.stop();
		}
	}
}
class Driver
{
	public static void main(String[] args)
	{
		new ChildThread();
	}
}

 

Output of the above program is as follows:

Thread is in new state
Thread is in runnable state
Thread entering blocked state
Enter a string: hai
Thread suspended
Thread is running
Thread terminated
