Identifying capital letters in strings

Question

I need to read a string (in this case a sentence) and identify any 'words' in the sentence (excluding the first word of the sentence) that begin with capital letters OR are entirely made up of capital letters. I guess I use string tokenizer to braek the string into individual words, but how do I then 'spot' capital letters (either beginnig words or all through the word)?

Here's the script that completes the task you describe (that is, to the best of my knowledge based upon your description). Enjoy!

(Note - create a CapsLetters object and call testString; for instance:
CapsLetters myCaps = new CapsLetters();
boolean result = myCaps.testString("Hello There");
class CapsLetters{
     String caps[] = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"};
     String notCaps[] = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"};
     public boolean testString(String sentence){
          StringTokenizer sentenceWords = new StringTokenizer(sentence, " ");
          String tempStr;
          if (sentenceWords.hasMoreElements()){tempStr = sentenceWords.nextToken();}
          boolean validSentence = true;
          boolean allCaps = true;
          boolean firstCap = false;
          boolean otherCaps = false;
          while (sentenceWords.hasMoreTokens()){
               tempStr = sentenceWords.nextToken();
               allCaps = true;
               firstCap = false;
               otherCaps = false;
               int noCapsInc = 0;
               for (int i = 0; i < tempStr.length(); i++){
                    System.out.println(isCaps(tempStr.charAt(i)));
                    if (isCaps(tempStr.charAt(i))){
                         if (i == 0){
                              firstCap = true;
                         else{
                              otherCaps = true;
                    else{
                         allCaps = false;
                         noCapsInc++;
               if ((allCaps == false && otherCaps == true) || noCapsInc == tempStr.length()){
                    validSentence = false;
          return validSentence;
     public boolean isCaps(char letter){
          String letterStr = "" + letter;
          boolean capFound = false;
          for (int j = 0; j < caps.length; j++){
               if (caps[j].equals(letterStr)){
                    capFound = true;
     return capFound;
}
