这个问题我看了几天了，都没有找出原因。请帮帮我啊。
class Client implements Callback{
  public void callback(int p){
  System.out.println("callback called with "+p);
  }
  void nooIfaceMath(){
    System.out.println("classes that implement interfaces: "+
    "may also define other members,too.");
  }
}
class TestIface{
  public static void main(String args[]){
  Callback c = new Client();
  c.callback(42);
  }
}
怎么执行不了呢？哪里有错？

执行后的显示，我也看不懂：
E:\mypack\TestIface2.java:1: cannot resolve symbol
symbol : class Callback
location: class AnotherClient
class AnotherClient implements Callback{
^
E:\mypack\TestIface2.java:9: cannot resolve symbol
symbol : class Callback
location: class TestIface2
Callback c = new Client();
^
E:\mypack\Client.java:1: cannot resolve symbol
symbol : class Callback
location: class Client
class Client implements Callback{
^
