How to capitalize the first character of each word in a string

Question

Is there a function built into Java that capitalizes the first character of each word in a String, and does not affect the others?

Examples:

• jon

Answer 1

public static String toTitleCase(String word){
    return Character.toUpperCase(word.charAt(0)) + word.substring(1);
}

public static void main(String[] args){
    String phrase = "this is to be title cased";
    String[] splitPhrase = phrase.split(" ");
    String result = "";

    for(String word: splitPhrase){
        result += toTitleCase(word) + " ";
    }
    System.out.println(result.trim());
}
