偶然看到这样一道题目，用最简单最直接的方式随手写了一遍，代码就要敲着玩。。。

public class Test {

    public static void main(String[] args) {
        SimpleDateFormat sd = new SimpleDateFormat("HHmm");
        String time = sd.format(new Date());
        int first = Integer.parseInt(time.substring(0,1));
        int second = Integer.parseInt(time.substring(1,2));
        int third = Integer.parseInt(time.substring(2,3));
        int forth = Integer.parseInt(time.substring(3));
        System.out.println(printOne(first)+" "+printOne(second)+"  "+printOne(third)+" "+printOne(forth));
        System.out.println(printTwo(first)+" "+printTwo(second)+" ."+printTwo(third)+" "+printTwo(forth));
        System.out.println(printThree(first)+" "+printThree(second)+"  "+printThree(third)+" "+printThree(forth));
        System.out.println(printFour(first)+" "+printFour(second)+" ."+printFour(third)+" "+printFour(forth));
        System.out.println(printFive(first)+" "+printFive(second)+"  "+printFive(third)+" "+printFive(forth));
    }

    public static String printOne(int i){
        String str = "";
        if (i == 1 || i == 4){
            str = "    ";
        }else{
            str = " -- ";
        }
        return str;
    }

    public static String printTwo(int i){
        String str = "";
        if (i == 1 || i == 2 || i == 3 || i == 7){
            str = "   |";
        }else if (i == 0 || i == 4 || i == 8 || i == 9){
            str = "|  |";
        }else{
            str = "|   ";
        }
        return str;
    }

    public static String printThree(int i){
        String str = "";
        if (i == 0 || i == 1 || i == 7){
            str = "    ";
        }else{
            str = " -- ";
        }
        return str;
    }

    public static String printFour(int i){
        String str = "";
        if (i == 2){
            str = "|   ";
        }else if (i == 0 || i == 6 || i == 8){
            str = "|  |";
        }else{
            str = "   |";
        }
        return str;
    }

    public static String printFive(int i){
        String str = "";
        if (i == 1 || i == 4 || i == 7){
            str = "    ";
        }else{
            str = " -- ";
        }
        return str;
    }

}

确实比较丑了。。。
