Questions tagged [datainputstream]

A DataInputStream lets an application read primitive Java data types from an underlying input stream in a machine-independent way.

The DataInputStream class enables you to read Java primitives from InputStream's instead of only bytes. Wrap an InputStream in a DataInputStream and then you can read primitives from it. DataInputStreams represent Unicode strings in a format that is a slight modification of UTF-8.
