This class is a character input stream that uses a String object as the source of the characters it returns. When you create a StringReader, you must specify the String to read from. StringReader defines the normal Reader methods and supports mark( ) and reset( ). If reset( ) is called before mark( ) has been called, the stream is reset to the beginning of the specified string. StringReader is a character stream analog to StringBufferInputStream, which is deprecated as of Java 1.1. StringReader is also similar to CharArrayReader.
