    i did it by this method

    public class Solution {
        public static void main(String[] args) {
            //write your code here
            int j = 1;
     
            for (int i = 1; i < 11; i++) {
                System.out.print(i * j + " ");
                if (i == 10) {
                    System.out.println("");
                    j++;
                    break;
                }
            }
            for (int i = 1; i < 11; i++) {
                System.out.print(i * j + " ");
                if (i == 10) {
                    System.out.println("");
                    j++;
                    break;
     
                }
            }
            for (int i = 1; i < 11; i++) {
                System.out.print(i * j + " ");
                if (i == 10) {

                    j++;
                    break;
                }
            }

                }
            }
        }


    Can someone tell me how i could have done this better.

    I am trying to get my head around these loops, making it start on another line was really hard.

    The other question i just could not get to work was implementing the numbers into an array. can you do that in java like append into the array and use the loop to add values

    thanks

    Sam

    Looking at the output, it looks like the numbers at the start of each row are incremented by 1.
    The contents of the columns are incremented by the number of the row.
    So the whole thing could be in one set of nested loops.
    Increment the row number by one.
    Increment the contents of each column in a row by the row number.
    If you don't understand my answer, don't ignore it, ask a question.
