    Default how do I get this output?

     0 1 2 3 4 5 6 7 8 9 10 11 
    1 2 3 4 5 6 7 8 9 10 11 12
    2 3 4 5 6 7 8 9 10 11 12
    etc.
    This is what I have so far
     public static void printAdditionTable () {  
           for (int rows=0; rows<=11; rows++){
            printRow (rows);
                }	
          }
          public static void printRow(int i) {
              for(int num=i;num<12; num++)
                {
                     System.out.print(num +" ");
                }
     
                System.out.println();
                 }
    I do not know how to get my first row to only have 0-11 and not 0-12

    Can you post what the code currently outputs
    and also what you want the code to output.
    If you don't understand my answer, don't ignore it, ask a question.

    Is this what you want?

    The first line prints 12 numbers
    The second line prints some numbers, the last number is 12
    the third line prints some numbers , the last number is 12
    the next line prints some numbers, the last number is 12

    Looks like the printing should stop for two cases. Can you see them?

    yeah, and no
    Wait, I might have it
    public static void printAdditionTable () {  
           for (int rows=0; rows<=11; rows++){
            printRow (rows);
                }	
          }
          public static void printRow(int i) {
              for(int num=i;num<=12; num++)
                {
                     System.out.print(num +" ");
                }
     
                System.out.println();
                 }
