Question

I have a string containing many words.
The words has to be displayed based on the positions.

Example,

   String str = "Australia Canberra Adellide ";

The above string should be,

Australia should start at 0 and end at 20

Canberra should start at 20 and end at 30

Adellide should start at 30 and end at 50

This i will be displaying in a jtextarea

Are there any formatter available in java? or padding should be used?

Answer 1

You can pad strings with String.format() with the %-ns format specifier.

String s = String.format("%-20s%-10s%-20s","Hello","to","you.");
// "Hello               to        you.                "

If you want to intersperse letters between individual letters, your best bet is probably a simple regular expression (i.e., s.replaceAll(".", "$0 ")).
