HelloName.java is a standalone program that asks for the name on the standard output (screen), 
reads the string given in standard input (keyboard), and writes a kind greeting to the user.

== the article ==
HelloName.java is the simplest estension of [[HelloWorld.java]]. 

It uses ''java.io.InputStreamReader'' to read characters from the ''System.in'' 
and inserts them into a ''java.io.BufferedReader'' so all the inserted character are then available as a ''java.lang.String'' for easier processing. 

The ''InputStreamReader'' gets [[constructors|initialized]] with a ''InputStream'' which in this case is the standard input ''System.in''. It is then wrapped into the ''BufferedReader'' which reads and inserts into a buffer the inserted characters. 

the ''bufferedReader.readLine();'' is then used to retrieve the first line (the characters pressed before the return).
