    Default Help make addition table from stopping once it reaches 12

    This is what I'm trying to do:Write a static void method called printAdditionTable that prints a two dimensional addition table for the numbers 0 to 12. Use a helper method that takes an integer parameter and prints one row of the table to demonstrate your knowledge of encapsulation. Use for loops in your methods.


          public static void printAdditionTable (int i) {
     
    	int tablenum = i;
            int rows;
     
    	for (rows = 0; rows<=12; ++rows) {
                    int columns;
     
    		for (columns = 0; columns<=12; columns++) {
     
    			System.out.print  (tablenum + " ");  
     			tablenum+=1;
     
    			if (columns==12) {
    				tablenum = rows;
    				System.out.println();
     			} 
    		}
     
    	} 
    }

    The problems are that the first row is repeated and the numbers do not stop at 12 for the rest of the rows.

    the numbers do not stop at 12
    Where are there statements in the code to stop the numbers at 12?


    what value is passed to the method as its arg?


    What do you want the code to print out?
    If you don't understand my answer, don't ignore it, ask a question.
