FileOutputStream question

[Kruzer]

I something similiar to the post(s) about ZIP compression and I would like to know how to convert the snippet to stream binary files to a zip file.

String file = "C:\\test.zip";
            String[] args = { "C:\junk.pdf" };
            //FileOutputStream f = new FileOutputStream(file);
            FileOutputStream f = new FileOutputStream(file);
            CheckedOutputStream csum =
                new CheckedOutputStream(f, new Adler32());
            ZipOutputStream out =
                new ZipOutputStream(

[i]Do I convert this to a FileOutputStream of the file, that being a PDF?[/i]

[b]new BufferedOutputStream(csum)[/b]);

                        for (int i = 0; i < args.length; i++) {
                                BufferedReader in = new BufferedReader(new FileReader(args[i]));
                out.putNextEntry(new ZipEntry(args[i]));
                int c;
                while ((c = in.read()) != -1)
                    out.write(c);
                in.close();
            }
            out.close();
            // Checksum valid only after the file
            // has been closed!
            System.out.println("Checksum: " + csum.getChecksum().getValue());
            // Now extract the files:
            System.out.println("Reading file");
            FileInputStream fi = new FileInputStream(file);
            CheckedInputStream csumi =
                new CheckedInputStream(fi, new Adler32());
            ZipInputStream in2 =
                new ZipInputStream(new BufferedInputStream(csumi));
            ZipEntry ze;
            while ((ze = in2.getNextEntry()) != null) {
                int x;
                while ((x = in2.read()) != -1)
                    System.out.write(x);
            }
            System.out.println("Checksum: " + csumi.getChecksum().getValue());
            in2.close();
            // Alternative way to open and read
            // zip files:
            ZipFile zf = new ZipFile(file);
            Enumeration e = zf.entries();
            while (e.hasMoreElements()) {
                ZipEntry ze2 = (ZipEntry) e.nextElement();
                System.out.println("File: " + ze2);
                // ... and extract the data as before
            }
