请编写程序，用java输出 n×n 的乘法口诀表

以下是用Java编写的输出n×n乘法口诀表的程序：

import java.util.Scanner;

public class MultiplicationTable {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入n的值：");
        int n = scanner.nextInt();

        // 输出乘法口诀表
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n; j++) {
                System.out.print(i + "×" + j + "=" + i*j + "\t");
            }
            System.out.println();
        }
    }
}

运行程序后，输入n的值，即可输出对应的n×n乘法口诀表。

请编写程序，用java输出 n×n 的乘法口诀表 注：乘号为小写字母x；乘积域宽2格(右对齐)；两列之间空1格；行末没有空格。

public class MultiplicationTable {
    public static void main(String[] args) {
        int n = 9; // 乘法口诀表的大小
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n; j++) {
                System.out.printf("%d x %d = %2d ", i, j, i * j);
                if (j == n) {
                    System.out.println();
                } else {
                    System.out.print(" ");
                }
            }
        }
    }
}

运行结果：

1 x 1 =  1  1 x 2 =  2  1 x 3 =  3  1 x 4 =  4  1 x 5 =  5  1 x 6 =  6  1 x 7 =  7  1 x 8 =  8  1 x 9 =  9

在Eclipse或IDEA环境下编写按1×1=1\n 1×2=2\t 2×2=4...格式输出乘法口诀表的程序NineMultiplication，其中，每行的多个乘法公式之间用‘\t’分割

在Eclipse或IntelliJ IDEA中，你可以创建一个名为`NineMultiplication.java`的Java程序来生成并打印九九乘法表，按照指定格式。下面是一个简单的实现：

public class NineMultiplication {

    public static void printMultiplicationTable() {
        for (int i = 1; i <= 9; i++) {  // 循环从1到9，即九九乘法表
            for (int j = 1; j <= i; j++) {  // 内循环遍历当前行的所有数字
                System.out.print(i + "×" + j + "=" + i*j + "\t");  // 输出乘法公式并用'\t'分隔
            }
            System.out.println();  // 每行结束后换行
        }
    }

    public static void main(String[] args) {
        printMultiplicationTable();
    }
}

当你运行这个程序时，会看到1到9的乘法口诀表以指定的格式打印出来。
