public class Bground extends Thread{
public static void main(String argv[]){
Bground b = new Bground();
b.run();
}
public void start(){
for (int i = 0; i <10; i++){
System.out.println("Value of i = " + i);
}
}
}
这里类Bground继承了Thread 却没实现Thread类的run方法，应该编译器出错才对啊！？可是为什么在电脑上运行却是对的！？

run() is defined in Thread class, if b not override run(), b.run() will call run() inherited from Thread, and do nothing.
