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
}
}
------解决方案--------------------
- 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 }}
