Here is a small "Hello world" type program I wrote.

I hope it helps

Hi Myke,

Try this.

/**
 * Read a string from the console, terminating input with a newline.
 * @return The input string (null if exception).
 */
public static String readString() {
    int ch = 0;
    String  r = "";
    boolean done = false;

    while (!done) {
        try {
            ch = System.in.read();
            if (ch < 0 || (char)ch == '\n')
                done = true;
            else if ( (char) ch != '\r')    // ignore cr
                r = r + (char) ch;
         }
         catch(java.io.IOException e) {
             done = true;
             return null;
        }
    }
    return r;
}


Cheers,
Glenn.

For that, you need to wrap a BufferedReader around System.in . Now system.in
reads raw bytes, not characters (remember, characters in java are 2-byte
unicode values), so you need to wrap system.in in a InputStreamReader first.
This means that if a person is in Japan and types in JIS keyboard escape
codes, the reader will correctly convert to japanese unicode characters.
Enter a period on a line by itself to exit the loop.

import java.io.*;

public class go {
 public static void main(String[] av) throws IOException {
  BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

  String ln;
  do {
   ln = br.readLine();
   System.out.println(">>>" + ln + "<<<");
  } while(!".".equals(ln));
 }
}
