Manage Threading with PRIORITY in java

class A extends Thread
{
public void run()
{
System.out.println("Thread A Started");
for(int i=1;i<=4;i++)
{
System.out.println("\tForm Thread A : i="+i);
}
System.out.println("Exit From A");
}
}


class B extends Thread
{
public void run()
{
System.out.println("Thread B Started");
for(int j=1;j<=4;j++)
{
System.out.println("\tForm Thread B : j="+j);
}
System.out.println("Exit From B");
}
}


class C extends Thread
{
public void run()
{
System.out.println("Thread K Started");
for(int k=1;k<=4;k++)
{
System.out.println("\tForm Thread C : k="+k);
}
System.out.println("Exit From C");
}
}
