打印九九乘法表算法-java

递归实现：

private static void multiTable(int n) {    if (n == 1) {        System.out.println("1*1=1");    } else {        // 把递归调用放在输出之前，保证乘法表是正的        multiTable(n - 1);        for (int i = 1; i <= n; i++) {            System.out.print(i + "*" + n + "=" + i * n + "\t");        }        System.out.println();    }}

循环实现：

// 循环实现一System.out.println("循环实现一");for (int i = 1; i <= 9; i++) {    for (int j = 1; j <= i; j++) {        System.out.print(j + "*" + i + "=" + j*i + "\t");    }    System.out.println();}// 循环实现二System.out.println("循环实现二");int i = 1, j = 1;while (i <= 9) {    System.out.print(j + "*" + i + "=" + j*i + "\t");    j++;    if (j > i) {        j = 1;        i++;        System.out.println();    }}
