How to generate hash code of Zip file.

In this tutorial, we will see how to generate hash code of zip file entries. The ZipFile
class is used to read entries of zip files. The entries() methods of ZipFile class returns
enumeration of zip file entries. The hashCode() method of ZipFile class returns hash
code of associated entry. The hasMoreElements() of Enumeration class check the
availability of more entries in zip file, and nextElement() method returns next
element of entry.

About ZipFile API:

The java.util.zip.ZipFile class extends java.io.FilterIntputStream class. It
provides the following methods:

Return Type	Method	Description
int	hashCode()	The hashCode() method returns hash code of associated method.
enumeration	entries()	The entries() method returns enumeration of entries of zip file.

code


import java.io.*;

import java.util.zip.*;

import java.util.zip.ZipFile;

import java.util.zip.ZipEntry;

import java.util.Enumeration;

import java.io.IOException;



public class ZipHashCode {

  public static void main(String args[]) {

    try {

      ZipFile zipName = new ZipFile("test.zip");

      Enumeration enumEntries = zipName.entries();

      while (enumEntries.hasMoreElements()) {

ZipEntry zipEntry = (ZipEntry) enumEntries.nextElement();

        String zipEntryName = zipEntry.getName();

        int hCode = zipEntry.hashCode();

System.out.println("\tName of Zip file : " + zipEntryName);

     System.out.print("\tHashCode Of Zip File : " + hCode);

      }

      zipName.close();

    } catch (IOException ioe) {

      System.out.println("IOException : " + ioe);

    }

  }

}

Following is the output if you run the application

C:\>java ZipHashCode
Name of Zip file : bharat.txt
HashCode Of Zip File : 1455566828
