书上说用接口的方式比用继承的方式好，因为是初学还没体会到，想问一下如何把下面的代码
改成接口的方式。
public class setPriority{
public static void main(String args[]){
MyThread t1 = new MyThread3("t1");
MyThread t1 = new MyThread3("t2");
t1.start();
t2.start();
}
}
class MyThread3 extend Thread{
MyTherad3(String s){super(s);}
public void run(){
for (int i=1;i<100;i++){
System.out.println(getName()+":"+i);
if(i%10==0){
yield();
}
}
}
}
------解决方案--------------------
在你原有的类上加了些代码
- Java code
public class setPriority{ public static void main(String args[]){ MyThread3 t1 = new MyThread3("t1"); MyThread3 t2 = new MyThread3("t2"); t1.start(); t2.start(); Thread t3 = new Thread(new MyThread4());//以MyThread4类的实例作为参数 t3.start(); } } class MyThread3 extends Thread{ MyThread3(String s){ super(s); } public void run(){ for (int i=1;i <100;i++){ System.out.println(getName()+":"+i); if(i%10==0){ yield(); } } } }class MyThread4 implements Runnable{ //实现Runnable接口 public void run(){ //some codes }}
