20.6. The Data Byte Streams
Reading and writing text characters is useful, but you also frequently
need to transmit the binary data of specific types across a stream. The
DataInput
and
DataOutput
interfaces define methods that transmit primitive
types across a stream. The classes
DataInputStream
and
DataOutputStream
provide a default implementation for each interface. We cover the inter-
faces first, followed by their implementations.
20.6.1.
DataInput
and
DataOutput
The interfaces for data input and output streams are almost mirror im-
ages. The parallel read and write methods for each type are
Read

readByte
writeByte

readShort
