Slip 12 - B) Write a program in java which will show lifecycle (creation, sleep, and dead) of a thread. Program should print randomly the name of thread and value of sleep time. The name of the thread should be hard coded through constructor. The sleep time of a thread will be a random integer in the range 0 to 4999.

Solution:

import java.util.*;

 

class DemoThread extends Thread

{

DemoThread(String nm)

{

super(nm);

}

public void run()

{

}

}

public class Slip12_q2

{

public static void main(String args[]) throws InterruptedException

{

DemoThread t1=new DemoThread("EnumTech");

System.out.println(t1.getState());

t1.start();

System.out.println(t1.getState());

System.out.println("Thread is running");

System.out.println(t1.getName());

Random r=new Random();

int s=r.nextInt(5000);

System.out.println("Thread will sleeping for " + s + "millisecs"); 

try

{

t1.sleep(s);

}

catch(InterruptedException ie)

{

}

t1.join();

System.out.println("Thread is no more");

System.out.println(t1.getState());

}

}
