regarding Threads

[Ushach]

hi all,
my sample code is like this.

public Classs X
{
int n[]=new int[10];
public void Xdes()
{
Z z=new Z();
z.Zdes(n);
}
public class Z
{
public void Zdes(n)
{
//3loops which iterare nearly 10000 time
}
}

I want to call the method Zdes(n) by using run() method of thread class.
I have wriiten the code as

public class Xdes() implements Runnable
{
int n[]=new int[10];
Z z=new Z();
t=new Thread(this,"H");
t.start();
}
public void run()
{
z.Zdes(n);
}

But it is giving me Exception.How to avoid that?
Is there any other way to write this code.
Main idea is code in Zdes(n) should be added to a thread.

What is the exact Exception that's being thrown? btw you'd better give your
classes and methods descriptive names for readability reasons.

kind regards,

Jos
