Class Test implements Runnable
{
public void one(){
{
System.out.println("Thread start");
Thread tt = new Thread(this);
tt.start();
}
}
--------------------------------------------
I want to change the above code to this:
Class Test implements Runnable
{
public void one(){
{
System.out.println("Thread start");
MyThread tt = new MyThread(this);
tt.start();
}
}

the MyThread isn't the instace of Thread!! ,but it has the start method!
class MyThread
{
MyThread(Runnable _runnable)
{
}

public void start()
{
}
}
