Can I transform this in bytecode?

Question

Hi guys
Here I am again.
I have this file.
I compile it so I can Obtain the class file.
Can I obtain from the class file a binary file?
If yes how can I do this?
(bytecode means binary file no?)
The file is:
import java.net.*;
import java.io.*;
import java.util.*;
public class CollabServer {
public int contator,contatore,cont;
public CollabServer() throws IOException {
contator = 0;
contatore = 0;
cont = 0;
ServerSocket server = new ServerSocket(5000);
System.out.println ("Accepting connections...");
while(true) {
if(contatore< 3){
Socket client = server.accept();
cont++;
System.out.println ("Accepted from " + client.getInetAddress());
new CollabHandler(client,cont).start();
contatore = CollabHandler.activeCount();
System.out.println ("contatore e' : " + contatore);
contator = CollabHandler.activeCount();
if (contator == contatore - 1) { contatore --; cont--;}
if (cont == 2) { server.close();}
public static void main(String args[]) throws IOException {
new CollabServer();
Any suggestions are treasure for me.
Thanks Maddy

Another example of source code more simple can help you have some ideas?
here's the source code:
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class window1 extends JFrame {
public window1() {
setSize(400,150);
setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE);
Map2 msg1 = new Map2();
this.getContentPane().add(msg1);
setVisible(true);
class Map2 extends JPanel {
public void paintComponent(Graphics comp) {
Graphics2D comp3 = (Graphics2D)comp;
comp3.drawString(" this is an example", 50, 50);
