用java输出九九乘法表，每个表达式的乘法结果长度为3

下面是用Java输出九九乘法表，每个表达式的乘法结果长度为3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++) {
                int result = i * j;
                String resultStr = String.format("%3d", result);
                System.out.print(j + " x " + i + " = " + resultStr + "  ");
            }
            System.out.println();
        }
    }
}
