请使用Java写一个九九乘法表

好的，下面是Java代码实现九九乘法表：

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) + "  ");
            }
            System.out.println();
        }
    }
}

输出结果如下：

1 × 1 = 1  
1 × 2 = 2  2 × 2 = 4  
1 × 3 = 3  2 × 3 = 6  3 × 3 = 9  
1 × 4 = 4  2 × 4 = 8  3 × 4 = 12  4 × 4 = 16  
1 × 5 = 5  2 × 5 = 10  3 × 5 = 15  4 × 5 = 20  5 × 5 = 25  
1 × 6 = 6  2 × 6 = 12  3 × 6 = 18  4 × 6 = 24  5 × 6 = 30  6 × 6 = 36  
1 × 7 = 7  2 × 7 = 14  3 × 7 = 21  4 × 7 = 28  5 × 7 = 35  6 × 7 = 42  7 × 7 = 49  
1 × 8 = 8  2 × 8 = 16  3 × 8 = 24  4 × 8 = 32  5 × 8 = 40  6 × 8 = 48  7 × 8 = 56  8 × 8 = 64  
1 × 9 = 9  2 × 9 = 18  3 × 9 = 27  4 × 9 = 36  5 × 9 = 45  6 × 9 = 54  7 × 9 = 63  8 × 9 = 72  9 × 9 = 81
