Java in a Nutshell, 5th Edition [Electronic resources]

This class is a character input stream that uses a character array as the source of the characters it returns. You create a CharArrayReader by specifying the character array (or portion of an array) it is to read from. CharArrayReader defines the usual Reader methods and supports the mark( ) and reset( ) methods. Note that the character array you pass to the CharArrayReader( ) constructor is not copied. This means that changes you make to the elements of the array after you create the input stream affect the values read from the array. CharArrayReader is the character-array analog of ByteArrayInputStream and is similar to StringReader.
