Java思考题——给定一个年份，让你判断出来该年对应天干地支纪年法的名称及生肖（三种方法实现）

代码实现

//测试主方法
public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("输入想要查询生肖的年份：");
        int year=input.nextInt();
        TDyear(year);
        TDyearArray(year);
        TDyearArrayList(year);
  }

//方法一：用简单清晰明了的switch语句实现
public static void TDyear(int year){
        int T=(year-3)%10;
        int D=(year-3)%12;

        switch(T){
            case 1:System.out.print("甲");break;
            case 2:System.out.print("乙");break;
            case 3:System.out.print("丙");break;
            case 4:System.out.print("丁");break;
            case 5:System.out.print("戊");break;
            case 6:System.out.print("己");break;
            case 7:System.out.print("庚");break;
            case 8:System.out.print("辛");break;
            case 9:System.out.print("壬");break;
            case 0:System.out.print("癸");break;
        }

        switch(D){
            case 1:System.out.println("子鼠年");break;
            case 2:System.out.println("丑牛年");break;
            case 3:System.out.println("寅虎年");break;
            case 4:System.out.println("卯兔年");break;
            case 5:System.out.println("辰龙年");break;
            case 6:System.out.println("巳蛇年");break;
            case 7:System.out.println("午马年");break;
            case 8:System.out.println("未羊年");break;
            case 9:System.out.println("申猴年");break;
            case 10:System.out.println("酉鸡年");break;
            case 11:System.out.println("戌狗年");break;
            case 0: System.out.println("亥猪年");break;
        }

    }

//方法二：用字符串数组进行改进
public static void TDyearArray(int year){
        int T=(year-3)%10;
        int D=(year-3)%12;

        String[] TT={"癸","甲","乙","丙","丁","戊","己","庚","辛","壬"};
        String[] DD={"亥猪年","子鼠年","丑牛年","寅虎年","卯兔年","辰龙年","巳蛇年","午马年","未羊年","申猴年","酉鸡年","戌狗年"};
        System.out.println(TT[T]+DD[D]);
    }

//方法三：用ArrayList集合进行修改
public static void TDyearArrayList(int year){

        int T=(year-3)%10;
        int D=(year-3)%12;

        ArrayList<String> list1 = new ArrayList<>();
        ArrayList<String> list2 = new ArrayList<>();

        list1.add("癸");
        list1.add("甲");
        list1.add("乙");
        list1.add("丙");
        list1.add("丁");
        list1.add("戊");
        list1.add("己");
        list1.add("庚");
        list1.add("辛");
        list1.add("壬");

        list2.add("亥猪年");
        list2.add("子鼠年");
        list2.add("丑牛年");
        list2.add("寅虎年");
        list2.add("卯兔年");
        list2.add("辰龙年");
        list2.add("巳蛇年");
        list2.add("午马年");
        list2.add("未羊年");
        list2.add("申猴年");
        list2.add("酉鸡年");
        list2.add("戌狗年");
        System.out.println(list1.get(T)+list2.get(D));
     }
