You can also make loops that decrements its index. That's basically what you need to add.for (int i = 1; i <= height; i++) {
    // This loops generate numbers from i to i+(i-1)
    for (int j = 0; j < i; j++) {
        System.out.print(i + j);
    // Here you need to print numbers in decreasing order
    // so find starting value, and stop condition
    System.out.println();
another problem is , how do u get 0 after 9 instead
of 10?
eg, 67890109876The modulo operator will make it (it divides one operand by another and returns the remainder as its result will make it.)
