访问已隐藏在第三个扩展类中的间接超类变量

问题描述

假设我有以下代码：

    class A {
    int a = 1; 
    }

    class B extends A {
    int a = 2; 
    }

    class C extends B {
    int a = 3;

    void print_it() {
    int a = 4;  // Local variable "a" to the " print_it " method

    System.out.println(a);       //Should be 4

    System.out.println(this.a);  //Should be 3

    System.out.println(super.a); //Should be 2

    System.out.println("HOW DO I PRINT \" a \" OF THE \" CLASS A      \" ");      //I need to print 1  
    }

    public static void main(String[] argue) {
    C obj = new C();               
    obj.print_it();
    } 
    }

如何访问类中的a一个间接继承到C类。我知道我可以创建一个A类的对象，我也知道我可以在B类中创建一个方法来返回super.a（a变量A类，当然如果它是静态的，我可以像Aa那样访问它。

How can i access "a" of the "class A" indirectly inherited to "class C".I know i can create an object of the " class A ", i also know i can create a method in "class B" to return "super.a" ( "a" variable of the "class A"), of course if it were static i could have accessed it like "A.a".

如果有任何其他方法可以直接访问它我。

If there is any other method to access it directly kindly enlighten me.

（提前感谢）。

推荐答案

转换为A然后访问变量：

Cast to A and then access the variable:

((A)this).a
