dealing with (zip) files

[aloula]

hi guys..

is there any - well documented - library that supports dealing with encrypted compressed files (zip, rar, 7z, ..etc)



any help would be appreciated

thanks in advance :)

Check API.

if you asking how to create a zip and read a zip, then i got a code example for you.

Making a zipped file..

package ZipWars;

import java.io.*;
import java.util.zip.*;

public class Zipping {
	public static void main(String[] args) throws IOException{
		
		ZipOutputStream out = new ZipOutputStream(new 
		BufferedOutputStream(new FileOutputStream("c:\\CrapMap\\ZipWarsFirstExample.zip")));
		byte[] data = new byte[10000];     
		
	try{
		BufferedInputStream in = new BufferedInputStream
						(new FileInputStream("c:\\CrapMap\\KlantenBestand.txt.txt"));
		
		out.putNextEntry(new ZipEntry("c:\\CrapMap\\KlantenBestand.txt.txt"));
		int count;
	 	while((count = in.read(data,0,10000)) != -1){
       		
		out.write(data, 0, count);
		}
	 	in.close();
	        out.flush();
	        out.close();
		System.out.println("Your file is zipped");
		
	}catch(Exception e){
 		e.printStackTrace();
	 }
	}
  }

Reading from the zipped file...

package ZipWars;

import java.io.*;
import java.util.zip.*;



public class ReadIt {
	public static void main(String[] args) throws IOException{
	 	ZipInputStream zis = null;

	    FileInputStream fis = new FileInputStream("c:\\CrapMap\\ZipWarsFirstExample.zip");
	    zis = new ZipInputStream(fis);

	    ZipEntry ze;

	    while ((ze = zis.getNextEntry()) != null)
	      System.out.println(ze.getName());

	}
}

Also you can do this all with the DeflaterOutputStream.

All the best,

Dieter

Note that i made a mistake with the FilePath. So you need to change that.

Dear Dieter ..

thanks for your assistance, but what I want exactly is the way of unzipping ((encrypted)) files..

is there a library supporting encrypted (zip, rar, ...etc) files?

if there is, I'll appreciate a sample code :)

thanks a lot..

try API, i'm sure u will find your way in there.
