Examples of java.io.DataInputStream.readByte()

java.io.DataInputStream.readByte()
See the general contract of the readByte method of DataInput.
Bytes for this operation are read from the contained input stream. @return the next byte of this input stream as a signed 8-bitbyte. @exception EOFException if this input stream has reached the end. @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
