Problem in Unzipping the zip file

Question

Hi
I have created a program to unzip the zip files in the folder named after the zip file
it is working well well when u try to zip zip files put in a directory
i.e u create a folder name contents and put files into that and then zip it
but when u directly create a zip file , without putting in a folder
it creates the folder and zip the files outside the folder
Another problem is that with the path
for e.g. suppose the zip file name is contents and path should show
contents/filename.txt but there are some other files whose path shows
res/file.txt. In this case it creates a folder of res and put it outside the
folder with the name of zip file
I have pasted my code :
//Unzip the zip files to the folder with their name
import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FilenameFilter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;
// Getting the path to find the type of files
public class zipper implements FilenameFilter{
          String ext;
          public zipper(String ext)
               this.ext="." + ext;
          public boolean accept(File dir,String name)
               return name.endsWith(ext);
public static void main(String args[]) throws IOException
          try
                    String dir = "D:/";
                    File f2 = new File(dir);
                    FilenameFilter fn= new zipper("zip");
                    String ss[]=f2.list(fn);
               for ( int j = 0; j < ss.length; j++)
                    System.out.println(" Extracting ...." + ss[j]) ;
                    String zipFile = dir + ss[j];
                    ZipFile zf = new ZipFile(zipFile);
                    Enumeration entries = zf.entries();
                    String directoryName = zf.getName();
                    directoryName = directoryName.substring(0, (directoryName.indexOf(":" + File.separator) + 2));
                         String folderName = zf.getName();
                         folderName = folderName.substring(0, folderName.lastIndexOf("."));
                         File file1 = new File(folderName);
                         //File file1 = new File(entries.getName());
                         file1.mkdir();
               while (entries.hasMoreElements())
                         ZipEntry ze = (ZipEntry) entries.nextElement();
                         String path = directoryName + ze.getName() ;
                         String path1 = folderName + ze.getName();
                         //System.out.println(" : " + path);
                         if (ze.getName().endsWith("/"))
                                   File file = new File(path);
                                   file.mkdir();
                                   continue;
                                   //break;
                    BufferedReader bReader = new BufferedReader(new InputStreamReader(zf.getInputStream(ze)));
     StringBuffer fileBuffer = new StringBuffer(" ");
     String line ;
                    while ((line = bReader.readLine()) != null)
                              fileBuffer.append(line);
                              fileBuffer.append("\r\n");
                              //line = line + "\r\n";
                              //byte[] b = new byte[line.length()];
                              //b =line.getBytes();
                              //out.write();
                    String fileData = fileBuffer.toString();
     File f1 = new File(path);
                    f1.createNewFile();
                    //FileOutputStream out = new FileOutputStream(folderName + "/" + ze.getName());
                    FileOutputStream out = new FileOutputStream(path);
                    long size = ze.getSize();
                    byte[] data1 = new byte[fileData.length()];
                    for (int i = 0; i < fileData.length(); i++)
                              data1[i] = (byte) fileData.charAt(i);
     out.write(data1);
     out.close();
                    bReader.close();                         
               } catch (Exception e)
                         e.printStackTrace();
Thanks in Advance

Answer 1

String path = directoryName + ze.getName();
String path1 = folderName + File.separator+ ze.getName();
File f1 = new File(path); // pass path1 instead of path
f1.createNewFile();
FileOutputStream out = new FileOutputStream(path); // pass path1 instead of path
