    Default Nested loops

    I need to use a nested loop to print the following output but an unsure how to do it with the two zeros printing after the 9. Any help appreciated. Need to print:
    1122334455667788990011223344556677889900

    Thanks. This is a method that I wrote, but I had to print the zeros as literals in a separate print statement. I know that there must be a better algorithm.

    public static void drawNumbers(){
    		for (int line = 1; line <= 2; line++){
    			for (int i =1; i <= 9; i++){
    				for (int j =1; j<=2; j++){
    					System.out.print(i);
    				}
    			}	
    		System.out.print("00");
    		}
    	}

    I don't see any comments in the code that describes the steps the code is trying to take to solve the problem.
    Can you add some comments saying what the different parts of the code are trying to do?
    If you don't understand my answer, don't ignore it, ask a question.

    Have you heard of the remainder or modulus operator? I think that combined with one loop will accomplish the task.
