What is the max size of a zip file with the JDK1.5 ?

Question

Hello everybody,
I'm a french student and for a project, I need to create a zip file, but I don't know in advance the number and the size of files to include in my zip.
I wish to know if someone have the answer to my question : what is the max size of a zip file with the JDK1.5 ? I believe that with the JDK1.3, the limit size of a zip was about 2Go, wasn't ?
Thank you for all answer !
Good day !
PS : sorry for my very poor english ;-)

Here is all I have found for the moment :
...Okay, what about my suggestion of creating your own 10GB file?
Try this:import java.io.File;
import java.io.RandomAccessFile;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;
import java.util.Random;
class Main {
    public static void main(String[] args) {
        long start = System.currentTimeMillis();
        int mbs = 1024;
        writeFile("E:/Temp/data/1GB.dat", mbs);
        long end = System.currentTimeMillis();
        System.out.println("Done writing "+mbs+" MB's to disk in "+
                ((end-start)/1000)+" seconds.");
    private static void writeFile(String fileName, int numMegaBytes) {
        try {
            int numBytes = numMegaBytes*1024*1024;
            File file = new File(fileName);
            FileChannel rwChannel =
                    new RandomAccessFile(file, "rw").getChannel();
            ByteBuffer buffer = rwChannel.map(
                    FileChannel.MapMode.READ_WRITE, 0, numBytes);
            Random rand = new Random();
            for(int i = 1; i <= numMegaBytes; i++) {
                for(int j = 1; j <= 1024; j++) {
                    byte[] bytes = new byte[1024];
                    rand.nextBytes(bytes);
                    buffer.put(bytes);
            rwChannel.close();
        } catch(Exception e) {
            e.printStackTrace();
}On my machine it took me 43 seconds to create a 1GB file, so it shouldn't take too long to create your own 10GB. Then try zipping that file.
Good luck.
