OOPs is a programming technique designed to simplify convoluted programming concepts. In fundamental nature, object-oriented programming revolves around the idea of user- and system-defined chunks of data, and controlled means of accessing and modifying those chunks. Object-oriented programming consists of Objects, Methods and Properties. An object is basically a black box which stores some information. Object may have a way for you to read that information and a way for you to write to, or change in sequence. It may also have other less noticeable ways of interacting with the information.

Some of the information in the object may essentially be directly easily reached; other information may necessitate you to use a method to access it – conceivably because the way the information is stored internally is of no use to you, or because only certain things can be written into that information space and the object needs to check that you’re not going outside those limits. The directly reachable bits of information in the object are its properties. The difference between data accessed via properties and data accessed via methods is that with properties, you see accurately what you’re doing to the object; with methods, unless you created the object yourself, you just see the effects of what you’re doing.

Other JavaScripts pages you read will almost certainly pass on frequently to objects, events, methods, and properties. This tutorial will learn by example, without focusing too profoundly on OOP terminology. However, you will need a basic fundamental of these terms to use other JavaScript references. Your web page document is an object. Any web page may involve table, form, button, image, or link on your page is also an object. Each object has confident properties. For example, the background color of your document is written document.bgcolor. You would change the color of your page to red by scripts code writing the line document.bgcolor= red

Most objects have a certain collection of things that they can do. Different objects can do different things, just as a light can turn on and off. A new document is opened with the method document. Open () you can write “Introduction of Java to a document by typing document. Write (“Introduction of Java “). Open () and write () are both methods of the object: document.

If you own a closet filled with clothes, you know what it is like to have a mess that needs to be sorted and cleaned up. Well, your iTunes music collection is no different at all.

Sometimes too many songs that you have are not tagged properly, many of them are missing album names and artist names, some may have wrong track titles and most may not have any album art. If you were to try to clean up your music collection manually, this would take weeks of tedious work, to say the least.

The way to alleviate this situation is to perform a quick and successful and almost hassle-free iTunes cleanup.

Here are some tips to help you achieve this goal:

Do a back-up of your iTunes library
Delete the music that you do not want to keep
Do a manual deletion of all duplicates
Make use of software to remove bulk duplicates, especially if you have a large library
Remove deleted files which remain listed in your library
When your library is free of duplicates and deleted files, you can backup and convert to MP3
Fix meta data or information, erroneous song titles or album info – try fixing one album or folder at a time and saving over your back-up
Rebuild your iTunes library after making sure of your back-up above
Sort out and update your album artwork

You may decide to go the way of subscribing to a software to do this job for you. Enter ‘Tune Up’, your music’s new best friend, as some refer to it. The TuneUp iTunes cleanup product can be subscribed to free of cost, cleaning up to 500 songs. Over and beyond that, you can sign up for a one year unlimited song clean up subscription for $11.95, as well as a life time subscription of $19.95 (limited offer).

The TuneUp iTunes plug-in is by far the easiest way to clean up all the patchy and scattered information in your iTunes. All you have to do is drag and drop songs into TuneUp.

How does the TuneUp iTunes cleanup work? Remembering that every piece of music, no matter from what source, contains a certain audio signature, TuneUp will then compare that signature with the online music database ‘Gracenote’. It will then retrieve all the information and album art about the song and simply put it in iTunes. Voila!

TidySongs is another automatic cleanup tool which will alleviate the painful manual process of going through one song at a time to fix the missing information on your song list. If you choose to go this route, all you have to do is to download the TidySongs application. Because it is an AIR application download, once the download is finished, you will end up with a ZIP file on your desktop. Once unzipped, the application is ready to be launched. Just a note of caution should you choose to take advantage of TidySongs: once you launch the application, make sure your local iTunes application is running and not engaged with other activities, for example, synching to your iPod, iPhone or other music players or downloading of podcasts.
