//This is a sample program which shows how to input(read) characters from 
//console. As you can see that it uses class InputStreamReader which is from 
//package java.io.*. It then creates an object of this class. The parameter
//System.in in the constructor signifies that this object will read characters
//from keyboard. The nonstatic method read() reads one character from console 
//and returns its unicode. Please go through the code and understand it.
//For inputing integers or other primitive types, see the file
//Interactive_reading_integers.java
