推荐答案

我认为这个问题是，你的编译器设置被设置为Java 1.5，而不是Java的1.6。由于Java 1.6注释@Override不仅是可能的，用于从超类继承的方法也为从接口实现的方法。但是，如果你的编译器仍设置为1.5的问题是，他会检查，如果你从一个超类覆盖的方法。在你的榜样，这是不是因为你实现从接口的方法的情况。

I think the problem is that you're compiler settings are set to Java 1.5 instead of Java 1.6. Since Java 1.6 the annotation @Override is not only possible for inherited methods from a superclass but also for implemented methods from an interface. But if your compiler is still set to 1.5 the problem is that he will check if you're overwriting a method from a super class. In your example this is not the case since you're implementing a method from an interface.

作为一个侧面说明这将是很好的遵循 Java命名约定的中您的code。因此所有的类开头的大写字母。

As a side note it would be good to follow Java Naming Conventions in your code. So all classes begin with an upper case letter.
