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(); } } }
