Java Programming

Hi All,

I have acode which unzip all the files from a folder .This code picks up all the zipped files at a time and then unzip it and write them to another folder but now my requirement is changed ,suppose the source folder where all the zipped files are present is refreshed or updated with new zipped files regularly then how can I implement in my code multithreading to get several files by threads and send it for unzipping.

Please suggest with some example or edit my code.

package com.myprojcet;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;


public class Main {

/**
* Extracts a zip file
*/
public void extractZipFile() {

try {
String zipFileName = "C:\\soft\\test"; //Source folder for zipped files
//Create input and output streams
File SourceDir = new File(zipFileName);
File[] zipFiles = SourceDir.listFiles();

ZipInputStream inStream = null;
OutputStream outStream = null;

ZipEntry entry;
byte[] buffer = new byte[1024];
int nrBytesRead;

//Get next zip entry and start reading data

for(int i=0; i < zipFiles.length; i++) {
inStream= new ZipInputStream(new FileInputStream(zipFiles));
while((entry = inStream.getNextEntry()) != null) {
outStream=new FileOutputStream("C:\\soft\\test2\\"+entry.toString()); //destination folder for unzipped file
while ((nrBytesRead = inStream.read(buffer)) > 0) {
outStream.write(buffer, 0, nrBytesRead);
}
}
}
//Finish off by closing the streams
outStream.close();
inStream.close();

} catch (IOException ex) {
ex.printStackTrace();
}
}


/**
* @param args the command line arguments
*/
public static void main(String[] args) {
new Main().extractZipFile();
}

}

Thanks
Sumit
