Usage

From source file:br.univali.celine.lms.utils.zip.Zip.java

public void zip(ArrayList<String> fileList, File destFile, int compressionLevel) throws Exception {

    if (destFile.exists())
        throw new Exception("File " + destFile.getName() + " already exists!!");

    int fileLength;
    byte[] buffer = new byte[4096];

    FileOutputStream fos = new FileOutputStream(destFile);
    BufferedOutputStream bos = new BufferedOutputStream(fos);
    ZipOutputStream zipFile = new ZipOutputStream(bos);
    zipFile.setLevel(compressionLevel);//from w w w .j  a v a  2 s .com

    for (int i = 0; i < fileList.size(); i++) {

        FileInputStream fis = new FileInputStream(fileList.get(i));
        BufferedInputStream bis = new BufferedInputStream(fis);
        ZipEntry ze = new ZipEntry(FilenameUtils.getName(fileList.get(i)));
        zipFile.putNextEntry(ze);

        while ((fileLength = bis.read(buffer, 0, 4096)) > 0)
            zipFile.write(buffer, 0, fileLength);

        zipFile.closeEntry();
