shark.zd.接口与抽象函数

源码如下（参考JAVA编程百例）

 

package shark.zd.接口和抽象函数;
interface player{
    int flag=1;
    void play();
    void pause();
    void stop();
    
    
}
abstract class playing{
    public void display(Object sPara){
        
        System.out.println(sPara);
    }
    
    abstract void winRun();
    
    
}
public class newplay extends playing implements player{


    void winRun() {
        // TODO Auto-generated method stub

        display("winrun");
    }

    public void pause() {
        // TODO Auto-generated method stub

        display("pause");
    }

    public void play() {
        // TODO Auto-generated method stub

        display("play");
        
    }

    public void stop() {
        // TODO Auto-generated method stub

        display("stop");
    }
    public static void main(String[] arges){
        
        newplay ov = new newplay();
        ov.winRun();
        ov.pause();
        ov.play();
        ov.stop();
        
    }

}
