Run method in Thread subclass

Question

run method of Base calss is executing when I run this code. If I remove Base.run() it Test1.run() is getting executed. can anybody explain why.?
class Base extends Thread{
public native String getTime();
     Base(Runnable r)
          super(r);
     public void run()
          System.err.println("In Base");
public class Test1 implements Runnable {
boolean bStop;
public static void main(String argv[]){
     Test1 m = new Test1();
     m.go();
public void go(){
     Base ts = new Base(this);
     ts.start();
public void run(){
          System.out.println(" in Test1");
}

Answer 1

What you have done is very odd, and wrong. Why do you have a subclass to thread that overrides the run method?
This is what the default implementation for the run method in the Thread class looks like:
    public void run() {
        if (target != null) {
            target.run();
    }Where target is the runnable that you passed into the constructor. Your implementation of run does not invoke that runnable.
