    Default How can I produce this output without using the If statement.

    I have to create a calendar for a single month and I'm starting by trying to figure out how to start a new line after every week. However, I'm not aloud to use if statements which sucks because I know how to use them. I can't think of any other way to do this without using a TON of for loops which is not acceptable for the assignment. We haven't covered while loops either so that's also not an option. Only for loops. I don't need to be given code because I'd rather use my own but any kind of help besides that would be appreciated.

    This is what I have if I use an If statement:
    public class Calendar
    {
       public static void main(String[] args)
       {
          drawDates(31);   
       }
       public static void drawDates(int NumberOfDays)
       {
          int x = 1;
          for (int i = 1; i <= NumberOfDays; i++)
          {
             System.out.print(i + " ");
             x++;
             if (x > 7)
             {
                System.out.println();
                x = 1;
             }   
          }
       }
    }

    Output:
    1 2 3 4 5 6 7
    8 9 10 11 12 13 14
    15 16 17 18 19 20 21
    22 23 24 25 26 27 28
    29 30 31

    Look at a nested loop.
    Inner prints days in the current week
    outer prints the newline char
    If you don't understand my answer, don't ignore it, ask a question.

    replace conditional statement with the while loop.
    or
    use for(;x>7; ) instead of if(x>7)
