Write a java program to implement thread life cycle.

A.java

public class A extends Thread {
public void run()
{
System.out.println("Thread A");
System.out.println("i in Thread A ");
for(int i=1;i<=5;i++)
{
System.out.println("i = " + i);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println("Thread A Completed.");
}
}

B.java

public class B extends Thread {

public void run()
{
System.out.println("Thread B");
System.out.println("i in Thread B ");
for(int i=1;i<=5;i++)
{
System.out.println("i = " + i);
}
System.out.println("Thread B Completed.");
}
}

Main.java

public class Main {

public static void main(String[] args) {

//life cycle of Thread
// Thread's New State
A threadA = new A();
B threadB = new B();
// Both the above threads are in runnable state

//Running state of thread A & B
threadA.start();

//Move control to another thread
threadA.yield();
//Bolcked State of thread B
try {
threadA.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
threadB.start();
System.out.println("Main Thread End");
}
}
