java学习笔记2:对象的"引用"之二

还是对象引用的代码,嘿嘿:

class  Letter{
         char  c;
}

public   class  PassObject{
         static   void  f(Letter y)
        {
                y.c = ' z ' ;
        }
         public   static   void  main(String[] args)
        {
                Letter x = new  Letter();
                x.c = ' a ' ;
                System.out.println( " 1: x.c= " + x.c);
                f(x);
                System.out.println( " 2: x.c= " + x.c);
        }
}

结果是什么呢,"猜"好的就看下面的答案好了
