输入一个年份，输出框就能显示这一年是什么生肖

public class test {    public static void main(String[] args) {        Animal.zodiac(1910);    }}class Animal{    public static void zodiac(int num)    {    //默认一个年份，从这年开始算起        int x =1900;        int tmp=(num-x)%12;        switch(tmp)        {        case 0:            System.out.println("鼠");            break;        case 1:            System.out.println("牛");            break;        case 2:            System.out.println("虎");            break;        case 3:            System.out.println("兔");            break;        case 4:            System.out.println("龙");            break;        case 5:            System.out.println("蛇");            break;        case 6:            System.out.println("马");            break;        case 7:            System.out.println("羊");            break;        case 8:            System.out.println("猴");            break;        case 9:            System.out.println("鸡");            break;        case 10:            System.out.println("狗");            break;        case 11:            System.out.println("猪");            break;        }    }}
