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);
}

This should help you.

WordUtils.capitalize(str) (from apache commons-lang)

(Note: if you need "fOO BAr" to become "Foo Bar", then use capitalizeFully(..) instead)

or you can also do it as,

         String str="hello how are you".trim();
         String[] arr = str.split(" ");
         StringBuffer sb = new StringBuffer();

         for (int i = 0; i < arr.length; i++) {
             sb.append(Character.toUpperCase(arr[i].charAt(0)))
                 .append(arr[i].substring(1)).append(" ");
         }

         System.out.print(sb.toString());

WordUtils.capitalize(str) in apache commons should do the trick http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/text/WordUtils.html#capitalize(java.lang.String)
