How do I get this to output 12 strings per line

[Louie LaRue]

This is a program that randomizies the strings in the array 20 times
and outputs them in a single line. How do I make it output 12 strings
per line?

thanks, Lane

The fact that the array of strings is randomized is irrelevant for your
question. If someone gave you a list of strings and told you to write them
down (e.g. on a piece of paper) such that there were 12 strings per line,
how would you do it as a human?

No need to say so, just be patient and watch carefully!

for (int i=0; i<result.length; i++)
System.out.print (result);

At this point I'd insert a statement involving i, 12, the modulo
function and the println() method.

Hi,

Something like this will work:

for (int i=0; i<result.length; i++){
System.out.print (result);
if (i%12 == 11){
System.out.println("");
}
}

Note a few important things about this code:

1) You need curly braces around the code inside your FOR loop because
you are doing more than one thing i.e. have more than one statement
ended with a ";". I always use curly braces on my FORs, IFs etc even if
I am only doing one thing. That way I can always put in extra lines
like output lines without having to worry about the braces.

2) "i%12" means get the remainder from dividing i by 12. If i=0, i%12
will be 0. If i=12, i%12 will be 0... but if i=11, i%12 will be 11.
This means execute what is inside the IF every 12th time around..

Thank you very much Robert. This works but every fourth line it prints
17 strings per line. It works good enough for my purposes though. I
appreciate it very much.
