    ZipEntry zEntry = null;
    try {
        fis = new FileInputStream(filePath);
        zipIs = new ZipInputStream(new BufferedInputStream(fis));
        while((zEntry = zipIs.getNextEntry()) != null){
            try{
                byte[] tmp = new byte[4*1024];
                FileOutputStream fos = null;
                String opFilePath = "C:/"+zEntry.getName();
                System.out.println("Extracting file to "+opFilePath);
                fos = new FileOutputStream(opFilePath);
                int size = 0;
                while((size = zipIs.read(tmp)) != -1){
                    fos.write(tmp, 0 , size);
                }
                fos.flush();
                fos.close();
            } catch(Exception ex){

            }
        }
        zipIs.close();
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
