編譯器報(bào)錯(cuò)
package moblie;
public abstract class Telephone {
public abstract void call();
public abstract void message();
}
package moblie;
public class Cellphone extends Telephone {
@Override
public void call() {
// TODO Auto-generated method stub
System.out.println("通過(guò)鍵盤打電話");
}
@Override
public void message() {
// TODO Auto-generated method stub
System.out.println("通過(guò)鍵盤發(fā)短信");
}
}
這是我全部代碼 但是編譯器報(bào)錯(cuò) 說(shuō)
The method call() of type Cellphone must override or implement a supertype method
怎么回事？
