How to print out specific length of spacing between numbers?

Question

I want to be organize with the output so I want to do something like this

   1   2   3   4   5
........
  91  92  93  94  95
........
 101 102 103 104 105
etc....

So I was trying to figure out how to line them up with the correct amount of spacing between each number.

my first attempt is doing everything manually like this

System.out.print("  " + counter);

using a loop

show us your attempt first – Raman Shrivastava Sep 07 '15 at 21:22 — Raman Shrivastava, Sep 07 '15 at 21:22
btw check for the java's `printf()` method – Raman Shrivastava Sep 07 '15 at 21:24 — Raman Shrivastava, Sep 07 '15 at 21:24

You can use System.out.format using %<width>d where you replace <width> with the width you require (make sure everything fits in!):

System.out.format("%4d", number); // align to width of 4

To add newlines use %n:

System.out.format("%4d%n", 1);
System.out.format("%4d%n", 12);
System.out.format("%4d%n", 123);

Are you sure there isn't a percent sign missing somewhere? – Clashsoft Sep 07 '15 at 21:30

That should be `%4d` – David Conrad Sep 07 '15 at 21:31
nice, been programming java for half a year, i didn't know how to adjust the width in java. I know how in c++. %4d is correct, I just tested thanks! – user3345335 Sep 07 '15 at 21:54
