According to the Java.sun site:

Package java.io "Provides for system input and output through data streams, serialization and the file system. "

The reason it is imported is so that the BufferedReader and InputStreamReader can be used.

BufferedReader "Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines."

InputStreamReader is "a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset."

For more info go to the java.sun site yourself or go directly to

http://java.sun.com/j2se/1.4.2/docs/api/java/io/package-summary.html
