Java一行代码打印乘法口诀表 打印乘法口诀

突然看到一行python代码打印九九乘法口诀表。
那Java也(伪)实现一下吧 - , -

public class MultiTableSingleLine {
    public static void main(String[] args) {
        for (int i = 1; i <= 9; i++) for (int j = 1; j <= i; j++) System.out.print(String.format("%d x %d = %d", j, i, j * i) + ((j == i) ? "n" : "t"));
    }
}

输出:

1 x 1 = 1
1 x 2 = 2	2 x 2 = 4
1 x 3 = 3	2 x 3 = 6	3 x 3 = 9
1 x 4 = 4	2 x 4 = 8	3 x 4 = 12	4 x 4 = 16
1 x 5 = 5	2 x 5 = 10	3 x 5 = 15	4 x 5 = 20	5 x 5 = 25
1 x 6 = 6	2 x 6 = 12	3 x 6 = 18	4 x 6 = 24	5 x 6 = 30	6 x 6 = 36
1 x 7 = 7	2 x 7 = 14	3 x 7 = 21	4 x 7 = 28	5 x 7 = 35	6 x 7 = 42	7 x 7 = 49
1 x 8 = 8	2 x 8 = 16	3 x 8 = 24	4 x 8 = 32	5 x 8 = 40	6 x 8 = 48	7 x 8 = 56	8 x 8 = 64
1 x 9 = 9	2 x 9 = 18	3 x 9 = 27	4 x 9 = 36	5 x 9 = 45	6 x 9 = 54	7 x 9 = 63	8 x 9 = 72	9 x 9 = 81

喵喵喵。
-。-!
估计这篇文章会石沉大海,但还是把正经的写法展示一下吧。

public class MultTable {
    public static void main(String[] args) {
        for (int i = 1; i <= 9; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.printf("%d x %d = %dt", j, i, j * i);
            }
            System.out.println();
        }
    }
}
