用Java双重循环打印九九乘法表

Sure, here's the Java code to print the multiplication table:

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();
}

This will output the multiplication table from 1x1 to 9x9.
