请大神们帮我看看是哪里错了，谢谢！
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() {
System.out.println();
// TODO Auto-generated method stub
}
@Override
public void message() {
// TODO Auto-generated method stub
}
}
错误显示为：
Multiple markers at this line
- The method call() of type CellPhone must
override or implement a supertype method
- implements com.imooc.Telphone.call
