Hello all , I am a newbie in java .Learning core java concepts and i
got confused with this piece of code . The output of code is "Extends
Super" . First time it prints Extends because of overriding but why it
prints " super" later.

Thanks in advance.

Code goes as follow

class SuperShow{
public String str ="Super";
public void show(){
System.out.println(str);
}}
class ExtendsShow extends SuperShow{
 public String str = "Extend";
 public void show(){
 System.out.println(str);}
 public static void main(String[]args){
 ExtendsShow ext = new ExtendsShow();
 SuperShow sup = ext;
 sup.show();
 //ext.show();
 System.out.println(sup.str);
 //System.out.println( ext.str);
 }}
