 *         The java.io API defines two sets of classes for reading and writing
 *         streams: those with Stream in their name and those with Reader /
 *         Writer in their name.
 * 
 *         Differences between Streams and Readers/Writers 
 *         1. The stream classes are used for inputting and outputting all 
 *         types of binary or byte data. 
 *         2. The reader and writer classes are used for inputting and
 *         outputting only character and String data.
