Java The Complete Reference, Seventh Edition

594 Part II: The Java Library

Method Description

void close( ) Closes the invoking stream. Further write attempts will

generate anIOException.

void flush( ) Finalizes the output state so that any buffers are cleared.

That is, it flushes the output buffers.

void write(bytebuffer[ ]) Writes an array of bytes to the invoking stream.

void write(bytebuffer[ ], intoffset,

intnumBytes)

Writes a subrange ofnumBytesbytes from the arraybuffer,

beginning atbuffer[offset].

void write(intb) Writes a single byte to the invoking stream. The byte written

is the low-order byte ofb.

void writeObject(Objectobj) Writes objectobjto the invoking stream.
