java匿名类可以访问外部类的私有成员。 为什么此代码无法访问私有数据成员？

Question

I want to access private member of a class by anonymous class created in a different class. I am new to java, kindly please explain this and tell what i am doing wrong.

class movie{
    private String moviename="bahubali";
    void display(){
        System.out.println(moviename);
   }
}

public class InnerClass{ //main class

    public static void main(String[] args) {
        movie anonymous=new movie() {
            void display() {
                System.out.println(moviename+" in anonymous class");
            }
        };
    
        anonymous.display();
    }
}

Answer 1

Your anonymous class inherits from the class movie (you should make it Movie instead btw. to comply with Java standards).

Inheriting classes are granted access to protected members, not to private members.

So the fix in this case should be changing

private String moviename="bahubali";

to

protected String moviename="bahubali";

.
