Examples of java.io.DataOutputStream.writeLong()

java.io.DataOutputStream.writeLong()
Writes a 64-bit long to this output stream. The resulting output is the 8 bytes, highest order first, of val. @param val the long to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readLong()

            ByteArrayOutputStream bout = new ByteArrayOutputStream();

            // milliseconds
