Java program to implement thread priorities.

{

public void run ()

{

System.out.println (" Thread A started");

for (int i = 1; i < 5; i++)

System.out.println ("Exit from Thread A");

}} class B extends Thread

{

public void run ()

{

System.out.println (" Thread B started");

for (int i = 1; i < 5; i++)

System.out.println (" Thread B : i = " i);

System.out.println ("Exit from Thread B");

}} class C extends Thread

{

public void run ()

{

System.out.println (" Thread C started");

for (int i = 1; i < 5; i++)

System.out.println (" Thread C : i = " i);

System.out.println ("Exit from Thread C");

}} class ThreadPriority

{

public static void main (String args[])

{

A threadA = new A ();
