Hi dogma992, just as alpha said, what are the errors, post them and we'll see what we can do, and next time please use code tags.

If you mean line up the output in the console, use the \t character (tab) and it should do the trick. Hope this helps.

Example:

System.out.println ("djsdfgklsbd \t\t\t\t X");
System.out.println ("djsdfklsbd \t\t\t\t X");
System.out.println ("djsdfggklsbd \t\t\t\t X");

In the above example, even if the strings's lengths are different, the X's will be lined up.
