IO-Utilities

Whenever I take any new project, I always require my Utilities library which provides me following features:

1. Copying my library from dependency to  C Drive or  user's home directory in windows or *nix systems
2. Compressing/Decompressing any Images or files for uploading or transferring it over network
3. Getting extension of any file name in faster way

All this features can be achieved using just one library, and using this library is dam easy...even you can attach a listener to listen the processing i.e.

• Name, count, size, compression level, copying from & copying to path of the file which library is processing ..

To attach a listener use this code

import fileutilslibrary.CopyEvent;
import fileutilslibrary.FileUtils;
import fileutilslibrary.Listener;
import fileutilslibrary.ZipEvent;
import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Demo2 implements Listener{

    void start( ) throws IOException{
        FileUtils.getInstance().addListener(this);
     
        FileUtils.zipMyFolder(new File("C:\\Users\\Admin\\Desktop\\imgToVideo/RemoteDesktop"),
                  new File("C:/Users/Admin/Desktop/HMS Latest/RDnew.zip"),9);
                 

     
    }
    public static void main(String[] args) {
 
        try {
            // TODO code application logic here
            new Demo2().start();
        } catch (IOException ex) {
            Logger.getLogger(Demo2.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    @Override
    public void copyListener(CopyEvent e) {
        //notification about copying event
    }

    @Override
    public void zipListener(ZipEvent e) {
        //notification about zip event
        System.out.println( "name " +e.getZipingFileName() +  "\n" + "size " + e.getZipingFileSize() + "\n" +
        " count " + e.getFileCount( ) + "\n" +
        "level  " + e.getCompressionLevel() );
    }
}

Various Methods:-

Copy a Directory

FileUtils.copyDirectory(src, dest);

Copy a File

FileUtils.copyFile(src, dest);

Zip Directory 

FileUtils.zipMyFolder(src, dest);

Zip Directory With Custom Compression Level

FileUtils.zipMyFolder(src, dest, compressionLevel);

Note: Compression level must be between 0-9, by default 0 is used

Zip File

FileUtils.zipMyFile(src, dest);

Zip File With Custom Compression Level

FileUtils.zipMyFile(src, dest, compressionLevel);

Note: Compression level must be between 0-9, by default 0 is used

UnZip File

FileUtils.doUnZip(src, dest);

Get File Extension (10x faster)

FileUtils.getExtension(path);

Reverse a String

FileUtils.reverse(str);

Get File Name 

FileUtils.getName(pathToFile);

Note: The library is written in pure Java code except the Wallpaper class which throws NotSupportedOSException if OS is not supported by the library for more information see Javadoc included in the download package.

This library is totally compatible with various 3rd party zip utilities like winrar, which means you can zip your files programmatically and still use winrar for unzip'ing the file or vice-versa is also possible.

NTSystem VS System.getProperty("user.name")

Yesterday i was reviewing my friends code, In that i found a class called NTSystem my friend was actually using this class because of this method

public String getName(); //This method gets you the current logged in user

I asked him do you think this application will work in Linux and he replied yes of course then i smiled and said try it out he tried and call me this morning and said the application is throwing

ClassNotFoundException 

why so ?

Thing is that Beginners don't understand the working, they just somehow learn (in chalega ..chalega style) or copy the code from internet the things to know is, though Java is machine independent JVM is not .

JVM is exclusive made for each OS. 

Thats why when you use NTSystem class in windows it works like a charm but the code throws an Exception when you run it on some other OS just because the JVM don't know what NTSystem is !

If you had download the JDK for Linux, there you will not find the NTSystem class.

So the bottom line is if you want to get the current logged in user in Java always use 

System.getProperty("user.name");

This Method has 2 benefits

1. Your code will be machine independent
2. You will get the current logged in user
