int a=5;                                                int a=5;

int b=++a;                                           int b=a++;  

System.out.println("a:"+a);                   System.out.println("a:"+a);

System.out.println("b:"+b);                  System.out.println("b:"+b);

這第二個答案是不是下面的寫錯了應該a 跟 b都是五才對
