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

z
