J2ME in a Nutshell

Name

DataOutputStream

Synopsis

This is a subclass of OutputStream that implements the methods of the DataOutput interface, writing encoded data as a sequence of bytes to another OutputStream. Instances of this class can be created directly. In addition, they can also be obtained from various other sources, such as the openDataOutputStream method of the javax.microedition.io.Connector. This example returns a stream to write data to a network connection or some other type of data source accessed using the CLDC Generic Connection Framework.

Note that the CLDC version of this class is derived from OutputStream and not FilterOutputStream, as it is in J2SE. This is because the CLDC does not have a FilterOutputStream class.
