String line = console.readLine() StringTokenizer st = new StringTokenizer(line) st.hasMoreTokens() true String token = st.nextToken() process the token somehow false tokenizer is empty (but line is untouched)

String line = console.readLine() StringTokenizer st = new StringTokenizer(line) st.hasMoreTokens() true String token = st.nextToken() process the token somehow false thus st = new StringTokenizer(line) allows us to reprocess the string (if we need to)
