Fields can be hidden, but not overridden

class SuperShow {

public String str = "SuperStr";

public void show() {

System.out.println("Super.show: " + str); } }

class ExtendShow extends SuperShow {

public String str = "ExtendStr";

public void show() {

System.out.println("Extend.show: " + str); }

public static void main(String[] args) {

ExtendShow ext = new ExtendShow();

SuperShow sup = ext;

sup.show();

ext.show();

System.out.println(" sup.str = " + sup.str);

System.out.println(" ext.str = " + ext.str); }}

What will the output be ?
