Name
CharArrayReader
Synopsis
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
.
