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.
