一个Java方法覆盖的小问题

 1 class SuperClass{
 2     
 3 public SuperClass() {
 4     System.out.println("superclass ");
 5     show();
 6 }
 7 public void show() {
 8     System.out.println("super class show !");
 9 }
10 }
11 class Subclass extends SuperClass{
12     
13     public Subclass() {
14         super();
15         super.show();
16         System.out.println("subclass ");
17         show();
18     }
19     public void show(){
20         
21         System.out.println("sub class  show !");
22     }
23 
24 }
25 public class Test {
26 public static void main(String[] args) {
27     Subclass sub = new Subclass();
28 }
29 }

为什么这个结果?????
