Create a zip files in a special way

Question

Dear all,
Following my yesterday's posting, I would clarify my questions:
I successfully created a zip file which contains a folder structure and two files from strings. See attached codes.
However, I don't like the way that I physically created subfolder and files before add them to the zip file.
Is there any possibility to avoid that part of creating multiple folders?
Regards.

But I did not understand how to convert a String to ZipOutputStream with a user choosen file name and a user choosen folder structure.
I am blocked at that point. Sorry for repeating the same question.
That doesn't make sense to me. Even more so as your sample code suggests that you are familiar with Writer and ZipEntry concepts. Can you explain in detail where you are stuck or what part of my previous suggestion was unclear to you?
Scratch that, I think I finally understand your problem. I think the following sample code will get you on track:import java.util.zip.ZipOutputStream;
import java.util.zip.ZipEntry;
import java.io.FileOutputStream;
import java.io.BufferedWriter;
import java.io.OutputStreamWriter;
public class ZipTest {
    public static void main( String[] args ) throws Exception {
        final String[] content = {"bla", "blubber"};
        final String[] names = {"root/content1/c1.txt", "root/content2/c2.txt"};
        final String path = System.getProperty("user.home") + "/test.zip";
        ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(path));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(zos, "UTF-8"));
        for (int i = 0; i < content.length; ++i) {
            final ZipEntry entry = new ZipEntry(names);
zos.putNextEntry(entry);
bw.write(content[i]);
bw.flush();
zos.closeEntry();
// this will close zos, too
bw.close();
