Zipping Multiple Files In java

How to zip multiple files in java.

• First i have created files and save on server side.
• Then i have reading the file names and zip the created files.
• When zip file are created ,then delete those created file.

First i have created two files and save on server side.

      List<String> fileText = new ArrayList<String>(1);

            List<String> ListOfFiles = new ArrayList<String>(1);

            fileText.add("text file 1");

            fileText.add("text file 2");

            ListOfFiles.add("1");

            ListOfFiles.add("2");

The below code is used to read the created file names and then zipping the created files on server side

List<String> fileNames = new ArrayList<String>(1);

            File fileTEXT = null;

            BufferedWriter output = null;

            try {

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

                        String fileName = "E:/C-CDA/MU2_CDA_WORKSPACE/zippingFiles/example"

                                    + ListOfFiles.get(i) + ".txt";

                        System.out.println("file name are :" + fileName);

                        fileTEXT = new File(fileName);

                        output = new BufferedWriter(new FileWriter(fileTEXT));

                        output.write(fileText.get(i));

                        fileNames.add(fileName);

                        output.close();

                  }

       

      // out put file

                  ZipOutputStream out = new ZipOutputStream(new FileOutputStream(

                              "E:/C-CDA/MU2_CDA_WORKSPACE/zippingFiles/tmp.zip"));

                  // input file

                  // FileInputStream in = new

                  // FileInputStream("E:/C-CDA/MU2_CDA_WORKSPACE/zippingFiles/example.txt");

                  FileInputStream fis = null;

                  // name the file inside the zip file

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

                        fis = new FileInputStream(fileNames.get(i).toString());

                        BufferedInputStream bis = new BufferedInputStream(fis);

                        // Add ZIP entry to output stream.

                        File file = new File(fileNames.get(i).toString());

                        String entryname = file.getName();

                        out.putNextEntry(new ZipEntry(entryname));

                        // buffer size

                        byte[] b = new byte[1024];

                        int count;

                        while ((count = fis.read(b)) > 0) {

                              System.out.println();

                              out.write(b, 0, count);

                        }

                  }

                  out.close();

                  fis.close();

            } catch (IOException e) {

                  e.printStackTrace();

            }

            finally {

                  System.out.println("delete created files after zipping");

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

                        File ac = new File(fileNames.get(i));

                        ac.delete();

                  }

            }

      }
