Examples of java.io.DataInputStream.readShort()

java.io.DataInputStream.readShort()
See the general contract of the readShort method of DataInput.
Bytes for this operation are read from the contained input stream. @return the next two bytes of this input stream, interpreted as asigned 16-bit number. @exception EOFException if this input stream reaches the end beforereading two bytes. @exception IOException the stream has been closed and the containedinput stream does not support reading after close, or another I/O error occurs. @see java.io.FilterInputStream#in
