[問題] boxing/unboxing

[seekyou (galagala~￾N )]

  public class Yikes {
1.public static void go(Long n){System.out.println("Long ");}
2.public static void go(Short n){System.out.println("Short  ");}
3.public static void go(int n){System.out.println("int ");}
4.        public static void main(String[] args) {
5.                short y=6;
6.                long z=7;
7.                go(y);
8.                go(z);
9.        }
10.}


這是SCJP模擬試題,output是 int Long

為什麼line 8 有找到對應的方法而印出 Long,而line7就沒有呢?

謝謝指導
