III Character stream and byte stream and file

　　1. Byte stream

Input stream

Output stream

< / td > < td > < p align = "left" > close() closes this output stream and releases all system resources related to this stream.

< / td > < td > < p align = "left" > flush() flushes this output stream and forces all buffered output bytes to be written out.

< / td > < td > < p align = "left" > write (byte [] b) writes b.length bytes from the specified byte array to this output stream.

< / td > < td > < p align = "left" > write (byte [] B, int len) writes len bytes from the offset off in the specified byte array to this output stream.

< / td > < td > < p align = "left" > write (int b) writes the specified bytes to this output stream.

< / TR > < tr class = "tablerowcolor" bgcolor = "white" > < TD align = "right" valign = "top" width = "1%" > void < / td > < td > mark (int readaheadlimit) marks the current position in the stream

< / TR > < tr class = "tablerowcolor" bgcolor = "white" > < TD align = "right" valign = "top" width = "1%" > Boolean < / td > < td > marksupported() determines whether this flow supports mark() operation
