Examples of java.io.RandomAccessFile.writeShort()

java.io.RandomAccessFile.writeShort()
Writes the specified 16-bit short to the OutputStream. Only the lower 2 bytes are written with the higher of the 2 bytes written first. @param val the short to be written @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readShort() @see DataInput#readUnsignedShort()
