interface A {
int x = 0;
}
class B {
int x =1;
}
class C extends B implements A {
public void pX() {
System.out.println(x);
}
public static void main(String[] args) {
new C().pX();
}
} 请写出你的想法，如果你认为对或者错，那么请看下面的代码是对错呢？
interface Playable
{
void play();
}
interface Bounceable {
void play();
}
interface Rollable extends Playable, Bounceable {
Ball ball = new Ball("PingPang");
}
class Ball implements Rollable {
private String name;
public String getName() {
return name;
}
public Ball(String name) {
this.name = name;
}
public void play() {
ball = new Ball("Football");
System.out.println(ball.getName());
}
}
