ADDITIONAL SYSTEM INFORMATION :
i will send a sample of priority based program.you can check it which is not give output according to given priority in code....


class A extends Thread
{
int i;
public void run()
{
for(i=1;i<=5;i++)
System.out.println("i="+i);
System.out.println("Exit from Class A");
}
}
class B extends Thread
{
int j;
public void run()
{
for(j=1;j<=5;j++)
System.out.println("j="+j);
System.out.println("Exit from Class B");
}
}
class C extends Thread
{
int k;
public void run()
{
for(k=1;k<=5;k++)
System.out.println("k="+k);
System.out.println("Exit from Class C");
}
}

class mthread
{
public static void main(String args[])
{
A x=new A();
B y=new B();
C z=new C();

z.setPriority(Thread.MAX_PRIORITY); //not work bcz it depend on jvm not on u
y.setPriority(x.getPriority()+1);
x.setPriority(Thread.MIN_PRIORITY);

System.out.println("Started Thread A");
x.start();
System.out.println("Started Thread B");
y.start();
System.out.println("Started Thread C");
z.start();
}
}




A DESCRIPTION OF THE PROBLEM :
setPriority() method in java is not work according to user.beacuse JVM and then OS determine the priority of the thread in a program that's why user cannot able to get output according to them.then why java provide setPriority() method if this method not works properly. So I hope JAVA team action on it and resolve as soon as possiible.Thnakyou
