can method of subclass access private variables of superclass

1public class Base {
2
3    private int x;  // field is private
4
5    protected int getX() {  // define getter
6        return x;
7    }
8
9    protected void setX(int x) {  // define setter
10        this.x = x;
11    }
12}
13//Then you would use it in your child class like this:
14class Child extends Base{
15
16    void foo() {
17        int x = getX(); // we can access the method since it is protected.
18        setX(42);  // this works too.
19    }
20}
