0121 有关接口的使用练习

public interface IDo { //创建接口

    public void  cpu(int s) ; //定义一个带参数的 方法
    
    public boolean zuzhuang();//定义一个布尔型变量
    
}

 

public class diannao implements IDo { //创建一个类实现定义的接口

    @Override                      
    public void cpu(int s) {
        System.out.println("cpu:"+s);
    }

    @Override
    public boolean zuzhuang() {
        System.out.println("组装成功");
        return true;
    }

 

public class zuoye {

private IDo diannao;
    
    public IDo getdiannao() {
        return diannao;
    }

    public void setDo(IDo diannao) {
        this.diannao = diannao;
    }
    
    
    int  cpu ;
    
    boolean cpu()
    {

    }

    }
public static void main(String[] args) {
