Capitalize First Char of Each Word in a String Java

What would be the easiest way to write a function that makes the following String transformations; here are some examples:

 - hello --> Hello
 - hello world --> Hello World

I just have some tags in the Db, and I wan to ensure that have consistent case; I know of course this could be done in the traditional sense, but I’m just interested to know if there are more convenient/reliable functions that could help to accomplish this.

You can use capitalize or capitalizeFully in Apache Commons Lang class WordUtils (org.apache.commons.lang).

public static java.lang.String capitalize(java.lang.String str)

Capitalizes all the whitespace separated words in a String. Only the first letter of each word is changed. To convert the rest of each word to lowercase at the same time, use capitalizeFully(String).

public static java.lang.String capitalizeFully(java.lang.String str)

Converts all the whitespace separated words in a String into capitalized words, that is each word is made up of a titlecase character and then a series of lowercase characters.
