    Default aligning help

    System.out.print("\nList 2 : ");
    for (i = 0 ; i<list.length ; i++){
        list2 [i] =(int)(99*Math.random()+1);
       System.out.printf(list2[i], " %2d");
    }


    i have this code... i want to align numbers

    it gives 10 random numbers,, i have 2 lists so for example..

    2 3 20 39 1 90 88 58 2 10
    12 23 8 12 54 2 9 1 58 2

    2 3 20 39 1 90 88 58 2 10

    Not very good with print f. Try removing that space in " %2d"
    and changing it to "%2d".

    You could also just have for each list:

    System.out.print("\nList 2 : ");
    for (i = 0 ; i<list.length ; i++){
    list2 [i] =(int)(99*Math.random()+1);
    System.out.print(list2[i] + " ");
    }

    That should work, but I'm not sure.

    it doesnt work because if a number with 1 digit comes up then the alignment will be all messed up... need help my instructor specifically told us to watch out for the alignments...

    i think its printf because i want to assign the integer with only 2 places so 1 digit numbers will be inputed like 02 or 01 but the zeros will not be outputted...

    and yeah the code you gave me that was my first try btw hehe

    You're right. printf is the way to go. Read this API for the formatting codes:
