    Default How do I print my 2d array?

    I am making a hotel booking system and can only take bookings in the month of April. I am having trouble creating the booking calendar and am using a 2d array for the month April I am not sure if this is a good way or not if so could somebody advise me. I want to print the array out so it has the dates like so:

    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


    Here is my code:

    /*

    * and open the template in the editor.
    */
    package ofi;

    /**
    *
    * @author Adam2_000
    */
    public class BookingCalendar {


    public static void main(String[] args) {


    int[][] april = new int[5][7];

    //First Row

    april[0][0] = 1;
    april[0][1] = 2;
    april[0][2] = 3;
    april[0][3] = 4;
    april[0][4] = 5;
    april[0][5] = 6;
    april[0][6] = 7;

    //Second Row

    april[1][0] = 8;
    april[1][1] = 9;
    april[1][2] = 10;
    april[1][3] = 11;
    april[1][4] = 12;
    april[1][5] = 13;
    april[1][6] = 14;

    //Third Row

    april[2][0] = 15;
    april[2][1] = 16;
    april[2][2] = 17;
    april[2][3] = 18;
    april[2][4] = 19;
    april[2][5] = 20;
    april[2][6] = 21;

    //Fourth Row

    april[3][0] = 22;
    april[3][1] = 23;
    april[3][2] = 24;
    april[3][3] = 25;
    april[3][4] = 26;
    april[3][5] = 27;
    april[3][6] = 28;

    //Fifth Row

    april[4][0] = 29;
    april[4][1] = 30;



    System.out.print(april);
    }
    }

    Default Re: How do I print my 2d array?

    So you want to print a month. "like this" you say...

    Well then what you really want to do is print the weeks of the month

    Except that is not good enough, what you really want to do is print the days.

    Except that is not good enough, what you really want to do is print up to 7 days on a row, and if there are more than 7 days make a new row.

    So while there are less than 7 days on the current row, and there are days in the month left to print, print a day on the current row.
