创建静态内部类的对象
public class A {
public static class B {
public void fun() {
System.out.println("OK");
}
}

public static void main(String[] args) {
A a = new A();
A.B ab = new A.B();
//A.B b = a.new B();//为什么这样不行
//A.B b = new A().new B();//为什么这样不行
}
}


[解决办法]

Java code

public class A {    public static class B {        public void fun() {            System.out.println("OK");        }    }    public class C {        public void fun() {            System.out.println("OK");        }    }    public static void main(String[] args) {        A a = new A();        A.B ab = new A.B();        A.C b = a.new C();//成功        A.C c = new A().new C();//成功    }}
