Is there a simple way to split a String of words in Java?? e.g. "Hello World? How are you?"
into an array of strings with each element in the array representing one word. Such that the above sentence would be:

   answer[0] = "Hello"
   answer[1] = "World?"
   answer[2] = "How"
   answer[3] = "are"
   answer[4] = "you?"

essentially i need a function that takes the string and returns the array.

Thanks alot.

Try this:

String answer[] = new String[5];

StringTokenizer tokens = new StringTokenizer("Hello World? How are you?");

for(int i =0;i<answer.length;i++){
  answer[i] = tokens.nextToken();
}

Or if you are using Java 1.4

String question = "Hello World? How are you?";
String[] answer = question.split("\\s+");
