DataOutputStream and BufferedOutputStream are two important FilterOutputStreams.

To open a data stream to an output file, use:
|
| 3 |
DataOutputStream out =
-
new DataOutputStream (
-
new FileOutputStream( filename ) );
|
| 4 |
where filename is a filename string.
|
| 5 |
Note that DataOutputStream has methods to write any primitive type.

To open a buffered output stream, use:
|
| 7 |
BufferedOutputStream out =
-
new BufferedOutputStream (
-
new FileOutputStream( filename ) );

Only bytes may be written to a BufferedOutputStream.
