message like string[] args from main() methods
String message;
while ((message = in.readUTF()) != null) {
//String[] array = message; -- gives error incompatible types
System.out.print("* Message from peer: " + message + "\n");
}
How can I split the message so i could use like
if (message[0].equals("hi")) ..
else if (message[2].equals("hey")) ..

I don't understand your question. Does message contain a number of words that you want to split into an array of words? If so (and the words are separated by a space character) you can do that using the split method eg:String[] words = message.split(" ");

StringTokenizer st = new StringTokenizer(yourString," ");
//where second string parameter is your devider criteria
while(st.hasMoreTokens()){
System.out.println(st.nextToken());
}
this example will devide yourString to pieces jumping over each " " symbol. Beware that if u have 2 spaces together (" ") in yourString for ex. st.nextToken() will consider them as 2 separate spaces, and since we've put 1 space as a divider criteria it will give u an empty string between the spaces as a token.
Id recommend eliminating all more-than-one spaces between words in your string (dont forget to trim it) and only then apply the tokenizer.

Sun have recommended that String.split(..) or Scanner should be used in preference to StringTokenizer. It hasn't been deprecated, but it is effectively superceded.
A language that doesn't affect the way you think about programming is not worth knowing...
