Parallel Port Output

Question

...doing a school project where i connect the parallel port to a bread bord which connencts to motors etc...
i understand u use javax.comm.*; classes to access the parallel port.
rite now i have like this...
import javax.comm.*;
import java.io.*;
public class carPort {
  ParallelPort port;
  byte[] outputByte = new byte[8];
  public carPort() {
    port.setOutputBufferSize(8);
  public OutputStream getOutputStream() {
    try {
      return port.getOutputStream();
    } catch(Exception e) {
      return null;
  public void outputBit(byte bit, byte position) {
    try {
      outputByte[position] = bit;
      port.getOutputStream().write(outputByte);
    } catch(Exception e) { }
}lets say outputByte has these value inside the array
outputByte[0] = 1
outputByte[1] = 0
outputByte[2] = 1
outputByte[3] = 0
outputByte[4] = 1
outputByte[5] = 0
outputByte[6] = 1
outputByte[7] = 0
and i call the outputBit method...
and this executes
port.getOutputStream().write(outputByte);
will the result be.
PIN 1 = ON
PIN 2 = OFF
PIN 3 = ON
PIN 4 = OFF
PIN 5 = ON
PIN 6 = OFF
PIN 7 = ON
PIN 8 = OFF
(ps. i have an thread class that provides constant output)
i know i know i know...i should be using c++....
if the above isnt the output wut can i do to make that?
just i case u dont understand wut im trying to do lolz. im trying to output indiviudal raw bits through the parallel ports 8 pins.
thx =)

Answer 1

wut i want to do is to turn leds/motors on and off through the parallel port. to do that, pin 1 would like be the right motor. and pin 2 the left motor, and like pin 3 for an led...etc...if pin 1 is on than the right motor will go if its 0 then the motor wont go....
in other words i want the program to output raw bits not bytes to the individual pins of the parallel port.
