class WordContainsException extends Exception { //Parameterless Constructor public WordContainsException() {}

  //Constructor that accepts a message
  public WordContainsException(String message)
  {
     super(message);
  }

}

Usage:

try { if(word.contains(" ")) { throw new WordContainsException(); } } catch(WordContainsException ex) { //Process message however you would like }
