Unable to unpack a .tar file inside a zip file.?

Question

I need to unpack all the Files containing a zip file. But the Zip file also contains a .tar file in it. Consider the below path : Original ZIP path : E:\test\26-03-2016\order\7930199_1.zip Extracted path : E:\test\26-03-2016\order\7930199_1\ItemFile\1458887416277_12\ftp\content-providers\ewh-e\data\incomingabp

          In the Extracted path ,The folder contains a .tar file as OBX00000000005442A.tar and it has several folders with in it.

I have extracted upto incomingabp,But I am not able to extract the .tar file. Kindly help me to extract this .tar file.Below I have provided my snippet.

code starts here

static public void extractFolder(String zipFile) throws 
ZipException,     
 IOException 
{
System.out.println(zipFile);
int BUFFER = 2048;
File file = new File(zipFile);

ZipFile zip = new ZipFile(file);
String newPath = zipFile.substring(0, zipFile.length() - 4);

new File(newPath).mkdir();
Enumeration zipFileEntries = zip.entries();

// Process each entry
while (zipFileEntries.hasMoreElements())
{
    // grab a zip file entry
    ZipEntry entry = (ZipEntry) zipFileEntries.nextElement();
    String currentEntry = entry.getName();
    File destFile = new File(newPath, currentEntry);
    //destFile = new File(newPath, destFile.getName());
    File destinationParent = destFile.getParentFile();

    // create the parent directory structure if needed
    destinationParent.mkdirs();

    if (!entry.isDirectory())
    {
        BufferedInputStream is = new BufferedInputStream(zip
        .getInputStream(entry));
        int currentByte;
        // establish buffer for writing file
        byte data[] = new byte[BUFFER];

        // write the current file to disk
        FileOutputStream fos = new FileOutputStream(destFile);
        BufferedOutputStream dest = new BufferedOutputStream(fos,
        BUFFER);

        // read and write until last byte is encountered
        while ((currentByte = is.read(data, 0, BUFFER)) != -1) {
            dest.write(data, 0, currentByte);
        }
        dest.flush();
        dest.close();
        is.close();
    }

    if (currentEntry.endsWith(".zip")||currentEntry.endsWith(".tar"))
    {
        // found a zip file, try to open
        extractFolder(destFile.getAbsolutePath());
    }
 }
}
}

Can any one help me to extract this?

This question has been answered before here on SO. It is always best too search if the question already exists.

Anyway, here is a very similar question. Seems like using Apache Commons Compress is the way to go.
