J2ME in a Nutshell

Name

DataInputStream

Synopsis

This subclass of InputStream implements the methods of the DataInput interface, reading encoded data as a sequence of bytes from another InputStream. Instances of this class can not only be created directly, but can also be obtained from various other methods, such as the openDataInputStream method of javax.microedition.io.Connector. In this case, the openDataInputStream method returns a stream to read data from 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 InputStream and not FilterInputStream as in J2SE. This is because CLDC does not have a FilterInputStream class.
