Problem in Unzipping the zip files

[avik1612]

Hi,

I have created a program to unzip the file. It is unzipping the zip files when put in directory i.e folder inside folder but when i create a zip file without putting in a folder and try to unzip it. It unzips it but put the zipped file outside the folder created in the name of the zip file. I want it to be inside it.

Also when i do beyond compare of the two files i.e the zipped file and original file its shows difference.

What should i do

I have pasted the code below:


//Unzip the zip files to the folder with their name

import java.io.Buffere dReader;
import java.io.File;
import java.io.FileOut putStream;
import java.io.Filenam eFilter;
import java.io.IOExcep tion;
import java.io.InputSt reamReader;
import java.util.Enume ration;
import java.util.zip.Z ipEntry;
import java.util.zip.Z ipFile;


// 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(e xt);
}

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.prin tln(" Extracting ...." + ss[j]) ;
String zipFile = dir + ss[j];

ZipFile zf = new ZipFile(zipFile );
Enumeration entries = zf.entries();

String directoryName = zf.getName();
directoryName = directoryName.s ubstring(0, (directoryName. indexOf(":" + File.separator) + 2));

String folderName = zf.getName();
folderName = folderName.subs tring(0, folderName.last IndexOf("."));
File file1 = new File(folderName );
file1.mkdir();

while (entries.hasMor eElements())
{
ZipEntry ze = (ZipEntry) entries.nextEle ment();
String path = directoryName + ze.getName() ;

//System.out.prin tln(" : " + path);
if (ze.getName().e ndsWith("/"))
{
File file = new File(path);
file.mkdir();
//continue;
break;
}

BufferedReader bReader = new BufferedReader( new InputStreamRead er(zf.getInputS tream(ze)));
StringBuffer fileBuffer = new StringBuffer(" ");
String line ;

while ((line = bReader.readLin e()) != null)
{
fileBuffer.appe nd(line);
fileBuffer.appe nd("\r\n");
//line = line + "\r\n";
//byte[] b = new byte[line.length()];
//b =line.getBytes( );
//out.write(b);

}

String fileData = fileBuffer.toSt ring();
File f1 = new File(path);
f1.createNewFil e();
FileOutputStrea m out = new FileOutputStrea m(path);
//FileOutputStrea m out = new FileOutputStrea m(new File(folderName + "/" + ze.getName()));
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.printStackTra ce();
}
}

}


Thanks in Advance
