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:

Answer 1

I'm using the following function. I think it is faster in performance.

public static String capitalize(String text){
    String c = (text != null)? text.trim() : "";
    String[] words = c.split(" ");
    String result = "";
    for(String w : words){
        result += (w.length() > 1? w.substring(0, 1).toUpperCase(Locale.US) + w.substring(1, w.length()).toLowerCase(Locale.US) : w) + " ";
    }
    return result.trim();
}
