java程序写九九乘法口诀表

以下是一个用Java编写的九九乘法口诀表的程序：

public class MultiplicationTable {
    public static void main(String[] args) {
        for (int i = 1; i <= 9; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print(j + " × " + i + " = " + (i * j) + "\t");
            }
            System.out.println();
        }
    }
}

运行上述代码，将输出九九乘法口诀表。

用java 写一个乘法口诀表

下面是用Java实现乘法口诀表的代码：

public class MultiplicationTable {
    public static void main(String[] args) {
        for (int i = 1; i <= 9; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print(j + " x " + i + " = " + (i * j) + "\t");
            }
            System.out.println();
        }
    }
}

运行程序后，会输出以下乘法口诀表：

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	

用Java程序编写乘法口诀表

在Java中，编写乘法口诀表的简单程序可以利用for循环和数组来实现。以下是一个基本的例子：

public class MultiplicationTable {
    public static void main(String[] args) {
        int start = 1;
        int end = 9; // 可根据需要修改范围

        for (int i = start; i <= end; i++) {
            for (int j = start; j <= end; j++) {
                System.out.print(i + " * " + j + " = " + (i * j) + "\t");
            }
            System.out.println(); // 换行
        }
    }
}

在这个程序中，外层循环遍历乘数，内层循环遍历被乘数，每次循环都会打印出当前乘积。`System.out.print()` 和 `System.out.println()` 分别用于在同一行显示结果和换行，形成乘法口诀表的格式。
