Commonly Used Output Methods Defined by
DataOutputStream
Here is the constructor for
DataOutputStream
. Notice that it is built upon an instance
of
OutputStream
.
DataOutputStream(OutputStream
outputStream
)
Here,
outputStream
is the stream to which data is written. To write output to a file, you can
use the object created by
FileOutputStream
for this parameter.
DataInputStream
implements the
DataInput
interface, which provides methods for

,
and each
can throw an
IOException
.
DataInputStream
uses an
InputStream
instance as its found-

DataInputStream
reads data in its binary format, not its human-readable form. The con-
structor for
DataInputStream
is shown here:
