final static int BUFFER = 2048;
public static void main (String argv[]) {
try {
BufferedOutputStream dest = null;
FileInputStream fis = new FileInputStream("D:/serverdata/dates.zip");
// String root = "D:/clientdata/";
ZipInputStream zis = new
ZipInputStream(new BufferedInputStream(fis));
ZipEntry entry;
ZipFile zipfile = new ZipFile("D:/serverdata/dates.zip");
while((entry = zis.getNextEntry()) != null) {
int count;
byte data[] = new byte[BUFFER];
if(entry.isDirectory()){
     File dir = new File(entry.getName());
     if(!dir.exists()){          dir.mkdir();                 }      
FileOutputStream fos =null;
fos = new FileOutputStream(entry.getName());
dest = new BufferedOutputStream(fos, BUFFER);
while ((count = zis.read(data, 0, BUFFER))
!= -1) {
dest.write(data, 0, count);
dest.flush();
dest.close();
zis.close();
} catch(Exception e) {
e.printStackTrace();
Please give me solution.
Thanks in advance

try this one and change it as u like:
import java.util.zip.ZipFile;
import java.util.zip.ZipEntry;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Enumeration;
import java.io.File;
public class UnzipFile {
private static void doUnzipFiles(String zipFileName) {
try {
ZipFile zf = new ZipFile(zipFileName);
System.out.println("Archive: " + zipFileName);
// Enumerate each entry
for (Enumeration entries = zf.entries(); entries.hasMoreElements();) {
// Get the entry and its name
ZipEntry zipEntry = (ZipEntry)entries.nextElement();
if (zipEntry.isDirectory())
boolean success = (new File(zipEntry.getName())).mkdir();
else
String zipEntryName = zipEntry.getName();
System.out.println(" inflating: " + zipEntryName);
OutputStream out = new FileOutputStream(zipEntryName);
InputStream in = zf.getInputStream(zipEntry);
byte[] buf = new byte[1024];
int len;
while((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
// Close streams
out.close();
in.close();
} catch (IOException e) {
e.printStackTrace();
System.exit(1);
public static void main(String[] args) {
if (args.length != 1) {
System.err.println("Usage: java UnzipFile zipfilename");
} else {
doUnzipFiles(args[0]);
}
