Question

I need to create these patterns in java according to however many lines the user enters:

1
12
123
1234
12345

54321
4321
321
21
1


     1
    21
   321
  4321
 54321

I can do the first two but I cannot do the third.
Here is the code for the second:

public static void displayPatternII (int lines) {

    for (int i = 1; i <= lines; i++){
        for (int j = lines + 1 - i; j > 0; j--)
            System.out.print (j + " ");
        System.out.println();
    }
}

Answer 1

 public static void displayPatternIII (int lines) {

    for (int i = 1; i <= lines; i++){
      System.out.print(" ");
        for (int j = lines; j > 0; j--)
            System.out.print (j > i ? " " : j);
        System.out.println();
    }
}
