Question

I having a class named Shape which has two subclasses Shape1 and Shape2. In the Shape class I have variables Xpos and Xpos and methods namely:

public int getXpos(){
    return Xpos;
}

public void setXpos(int x){
    this.x = x;
}

// Same thing for y

Now let’s just say in the class Shape, x = 10. Now when I inherit it:

public class Shape1{
    Shape1(){
        xPos = 100;
        // ...
    }
}

and:

public class Shape2{
    Shape2(){
        xPos = 200;
        // ...
    }
}

But when I do Shape1.getX() in another program, I get 10 as a result. Can someone tell me why I’m not getting 100? Is the problem with the ‘this’ keyword?

Answer 1

xPos cannot be static. If it is static the same number will appear twice. (the original shape)
