创建java类中类出现is not an enclosing class
来源:互联网 发布:java相关网络协议卡死 编辑:程序博客网 时间:2024/06/14 18:34
public class A { public class B { } };
需要实例B类时,按照正逻辑是,A.B ab = new A.B();
那么编译器就会出现一个错误--"is not an enclosing class"
再翻看相关的java代码,发现原来写法出错了!正确的做法是
A a = new A();A.B ab = a.new B();
没有静态(static)的类中类不能使用外部类进行.操作,必须用实例来进行实例化类中类.
