在编译一个例子时,结果编译时出现:
No enclosing instance of type test8 is accessible. Must qualify the allocation with an enclosing instance of type W (e.g. x.new A() where x is an instance of W).
(W为文件名)
根据提示,没有可访问的内部类W的实例,必须分配一个合适的内部类W的实例(如x.new A(),x必须是W的实例。)
但是我已经实例化了这个类,为什么还不行呢。
经过查询相关资料。原来我写的内部类是动态的,也就是开头以public class开头,或者默认的为动态的。而主程序是public static class main。在Java中,类中的静态方法不能直接调用动态方法。只有将某个内部类修饰为静态类,然后才能够在静态类中调用该类的成员变量与成员方法。所以解决办法是将public class改为public static class.
