Thread: How do you align?

Hello, I wrote a program to generate the times tables. Now it works and everything but it is not aligned as in all the units, tens etc are not ordered. Basically, instead of:

1 2 3 4 5 6 7 8 9
2 4 6 8 10 12 14 16 18
3 6 9 12 15 18 21 24 27
4 8 12 16 20 24 28 32 36
5 10 15 20 25 30 35 40 45
6 12 18 24 30 36 42 48 54
7 14 21 28 35 42 49 56 63
8 16 24 32 40 48 56 64 72
9 18 27 36 45 54 63 72 81

I'm getting:

1 2 3 4 5 6 7 8 9
2 4 6 8 10 12 14 16 18
3 6 9 12 15 18 21 24 27
4 8 12 16 20 24 28 32 36
5 10 15 20 25 30 35 40 45
6 12 18 24 30 36 42 48 54
7 14 21 28 35 42 49 56 63
8 16 24 32 40 48 56 64 72
9 18 27 36 45 54 63 72 81

edit: damn it, it doesn't show here, but you get the gist I hope

Have a look at what "\t" does in a String(or System.out)

can you tell me where to look

In between numbers you will be printing a " ", have a look what happens if you print a "\t" instead

Not quite, see attached for what i want

The most simple way would be to have a set number of spaces between each number. remove spaces based on the number of characters (e.g. 27 is 2).

Otherwise you can use the Formatter class, there is quite a good tutorial:
Henrik Bengtsson's Java printf, sprintf, fprintf (scanf, sscanf and fprintf)
