Usage

From source file:ZipCompress.java

public static void main(String[] args) throws IOException {
    FileOutputStream f = new FileOutputStream("test.zip");
    CheckedOutputStream csum = new CheckedOutputStream(f, new Adler32());
    ZipOutputStream zos = new ZipOutputStream(csum);
    BufferedOutputStream out = new BufferedOutputStream(zos);
    zos.setComment("A test of Java Zipping");
    // No corresponding getComment(), though.
    for (int i = 0; i < args.length; i++) {
        System.out.println("Writing file " + args[i]);
        BufferedReader in = new BufferedReader(new FileReader(args[i]));
        zos.putNextEntry(new ZipEntry(args[i]));
        int c;//from w ww.j  av  a 2  s  .  co  m
        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("test.zip");
    CheckedInputStream csumi = new CheckedInputStream(fi, new Adler32());
    ZipInputStream in2 = new ZipInputStream(csumi);
    BufferedInputStream bis = new BufferedInputStream(in2);
    ZipEntry ze;
    while ((ze = in2.getNextEntry()) != null) {
        System.out.println("Reading file " + ze);
        int x;
        while ((x = bis.read()) != -1)
            System.out.write(x);
    }
    System.out.println("Checksum: " + csumi.getChecksum().getValue());
    bis.close();
    // Alternative way to open and read zip files:
    ZipFile zf = new ZipFile("test.zip");
    Enumeration e = zf.entries();
    while (e.hasMoreElements()) {
        ZipEntry ze2 = (ZipEntry) e.nextElement();
        System.out.println("File: " + ze2);
        // ... and extract the data as before
    }
