Capitalize words of a string

This is an example of how to capitalize the words of a String. We are using the org.apache.commons.lang3.text.WordUtils Class, that provides operations on Strings that contain words. The Class tries to handle null input gracefully. An exception will not be thrown for a null input. Trying to capitalize the words of a String implies that you should:

• Use capitalize(String str) API method of WordUtils to capitalize all the whitespace separated words in a String.
• Then use the capitalizeFully(String str) method of WordUtils. It 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.

Let’s take a look at the code snippet that follows:  

package com.javacodegeeks.snippets.core;

import org.apache.commons.lang3.text.WordUtils;
 
public class CapitilizeWords {
	
    public static void main(String[] args) {

  
    	// capitalize method capitalizes only the letters after space 

  String string = WordUtils.capitalize("JAVA Programming is COOL");

  System.out.println("Capitilize example 1 = " + string);
 

  // capitalizeFully method capitalizes the letters after space and the rest letters turn to lower case 

  string = WordUtils.capitalizeFully("JAVA Programming is COOL");

  System.out.println("Capitilize example 2 = " + string);
    }
}

Output:

Capitilize example 1 = JAVA Programming Is COOL
Capitilize example 2 = Java Programming Is Cool
