Examples of java.io.DataInputStream.readDouble()

java.io.DataInputStream.readDouble()
See the general contract of the readDouble method of DataInput.
Bytes for this operation are read from the contained input stream. @return the next eight bytes of this input stream, interpreted as adouble. @exception EOFException if this input stream reaches the end beforereading eight 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.DataInputStream#readLong() @see java.lang.Double#longBitsToDouble(long)
