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");
