Usage

From source file:Main.java

public void doZip(String filename, String zipfilename) throws Exception {
    byte[] buf = new byte[1024];
    FileInputStream fis = new FileInputStream(filename);
    fis.read(buf, 0, buf.length);/*  w w w.  j  a va 2  s .c o  m*/

    CRC32 crc = new CRC32();
    ZipOutputStream s = new ZipOutputStream((OutputStream) new FileOutputStream(zipfilename));
    s.setLevel(6);

    ZipEntry entry = new ZipEntry(filename);
    entry.setSize((long) buf.length);
    crc.reset();
    crc.update(buf);
    entry.setCrc(crc.getValue());
    s.putNextEntry(entry);
    s.write(buf, 0, buf.length);
    s.finish();
    s.close();
