java for循环乘法表

以下是使用Java的嵌套for循环打印乘法表的两种方法：

方法一：

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();
}

方法二：

for (int i = 1; i <= 9; i++) {
    for (int j = 1; j <= 9; j++) {
        if (j <= i) {
            System.out.print(j + "*" + i + "=" + (i * j) + "\t");
        }
        if (j == 9) {
            System.out.println();
        }
    }
}

这两种方法的区别在于第二个嵌套的for循环的条件判断和插入换行的时机。方法一的第二个for循环语句在j=i的时候就判断运行最后一次循环，然后在此循环结束时插入换行。方法二的第二个for循环语句会一直循环到j=9，在j=9时插入换行再退出循环。\[1\]\[2\]\[3\]
