If, instead, you want to “roll your own” code (why?!), in JDK 1.0.2 java.io.DataInputStream in = new java.io.DataInputStream(System.in); String s = in.readLine(); One way in JDK 1.1: java.io.BufferedReader in = new java.io.BufferedReader( new InputStreamReader(System.in)); String s = in.readLine(); Once you have the token in a String, it is easy to parse it into one of the other types, as shown earlier in the FAQ. Yes, it is bone-headed, as it makes the simplest case of ke
