Java中子类为什么访问父类的字段而不是自己的？

Question

class Parent {
    int money = 10000;
    int getMoney() {
        return money;
    }
}

class Child extends Parent {
    int money = 5000;
}

public class Test {

    public static void main(String[] args) {

        Child c = new Child();
        System.out.println(c.getMoney());
    }
}

The output is 10000. Also if I edit the getter to say return this.money I get the same result.

So why does Java take superclass's field but not the caller's ( Child ). I know Python more and it shouldn't be like this in Python.

Answer 1

You can't override variables in Java. The method is in the Parent class which means that money will access the variable in the Parent class also.

The thing that can be done in Java is hiding as opposed to overriding. If you declared the getter in the Child class then it would print 5000 as the Parent money variable has been hidden.

To address your edit about using this , it won't change anything. By referencing a variable in a class, you're already implicitly referring to this .
