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 .
