Streching String to fixed length in Java

[RageAx]

I want to create an output for my app that is always of fixed length. For example,  I have Strings of numbers that look like this: 

01 23 456
789 012 3 4
56 78 9 0 12
34 56 789

 

And I want to change it so it will always look like it's fixed length (like in Word when the text is filled with whitespaces to fill the page):

01   23  456
789  012 3 4
56 78 9 0 12
34   56  789 

 

Any help would be appreciated.

There isn't one correct way because there's more than one way to align the text within each line, but this is how i would approach this.

 

1) pick a max width

2) for each line:
            calculate the total number of white space elements, and divide by (n-1), where n is the number of non-white space groups
            write the non-whitespace groups, and put a number of white spaces between each group using the number above

There are edge cases to consider, (like even/odd line length, a line of all whitespace, a single non-whitespace group, etc.), but that's the general concept.

 

EDIT: actually it'd be simpler to just take the max line length, subtract the length of non-whitespaces, instead of directly counting whitespaces. It's early, I just got to work, and I haven't had any coffee, so there lol.
