Make String first letter capital in java

Question

As of now I'm using this code to make my first letter in a string capital

String output = input.substring(0, 1).toUpperCase() + input.substring(1); 

This seems very dirty to me ..is there any direct or elegant way..

Answer 1

How about this:

String output = Character.toUpperCase(input.charAt(0)) + input.substring(1); 

I can't think of anything cleaner without using external libraries, but this is definitely better than what you currently have.

Answer 2

You should have a look at StringUtils class from Apache Commons Lang lib - it has method .capitalize()

Description from the lib:

Capitalizes a String changing the first letter to title case as per Character.toTitleCase(char). No other letters are changed.
