/*
 * This example shows how to use BufferedReader. In Culwin's textbook 
 * and in our lecture, we have used DataInputStream for our readLine()
 * method. That is
 *   DataInputStream in = new DataInputStream(System.in)
 * This method has been deprecated in the newer versions of Java.
 * In newer version of Java, the readLine() method comes from
 * BufferedReader. This is an example of how to use it.
 * The BufferedReader is available in JDK 1.1. Our current J++ does
 * not support this.
 *
 * This version uses try/catch clause.
