请问是什么地方出错了？
package com.imooc;
public abstract class Telphone {
public abstract void call();
public abstract void message();
}
package com.imooc;
public class CellPhone extends Telphone {
@Override
public void call() {
// TODO Auto-generated method stub
}
@Override
public void message() {
// TODO Auto-generated method stub
}
}错误显示为
Multiple markers at this line
- implements com.imooc.Telphone.message
- The method message() of type CellPhone must
override or implement a supertype method
