    Default changing character repetition

    is it possible to use two arguments in a recursive method to change the indentation & the amount of repetition of a character without using a loop?

    If the recursive method was called twice, here's an example output of two lines if both arguments of the method were changed:

    gggggg

    I'm not really sure what you mean by this.

    In theory, anything you can do with a loop you can do with recursion, and vice versa. So the answer is probably yes. Is something like this what you're asking about?

    printRecursive(characters: integer, indent: integer)
    1. if indent > 0
    2.   then print indentation symbol
    3.   printRecursive(characters, indent - 1)
    4. else if characters > 0 
    5.   then print character symbol
    6.   printRecursive(characters - 1, 0)

    The translation to Java is pretty straightforward. Let me know if this helps answer your question.
