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

The following method converts all the letters into upper/lower case, depending on their position near a space or other special chars.

public static String capitalizeString(String string) {
  char[] chars = string.toLowerCase().toCharArray();
  boolean found = false;
  for (int i = 0; i < chars.length; i++) {
    if (!found && Character.isLetter(chars[i])) {
      chars[i] = Character.toUpperCase(chars[i]);
      found = true;
    } else if (Character.isWhitespace(chars[i]) || chars[i]=='.' || chars[i]=='\'') { // You can add other chars here
      found = false;
    }
  }
  return String.valueOf(chars);
}
