How to compare two text files and high light the difference using java?

I have two text file with some content, i need to compare two file line by line and high light the difference like any version control system (svn, cvs etc.). Could any one can help me here?

I have created a similar project. You can check this link. This will help you conceptually. I can provide the code also but that will not help your understanding. Try to implement yourself you will enjoy. \m/

I am new to the ANDROID developing and i really need your help to the beggining.
Thanks a lot.
Thanks for your help.

The Java Package name hierarchy is not meant to be a place to hardcode your database of movies into.
Preferably, learn to use SQLite for keeping that kind of data. Don't even bother using XML in this case.
Take a look at this tutorial.

Tutorial on how to import/read a tif/tiff file using java or the java advanced imaging API

I have a tiff image with many directories and subdirectories. I would like to navigate this tiff directory tree and import the image into a 2D array, so I can process this image. I am relatively new to java and cannot figure out how to do this. Will someone please reply to my question with a tutorial and examples of code?
Also, does anyone else find the java API documentation difficult to find, difficult to navigate, and somewhat sparse? I am trying to do this as a workaround for a processing sketch I am creating. Are there different workarounds?
Thank you.

Well i didn't even know a tiff could have directories and sub directories... But I would have a look in java File class as a start point to try to see those directories from your app. If you can see them, than you probably can parse them too.

concatenate multiple audio files in java

i have a java text-to-speech project and I want to concatenate the multiple audio files('ogg' format) so that i play them in one stream, anyone has any idea about it? can java do this? if you can lead me to any resource or tutorial or anything helpful I will be very pleased,
thanks a lot.

For concatenation I would use some external command-line tool via Runtime.exec() or ProcessBuilder.
Probably, oggcat should work in your case: http://en.flossmanuals.net/ogg-theora/command-line-editing/cat-files/ (it's about video, but ogg container is the same, make sense to try, anyway)
As for playing, there is JOrbis library and probably something else.

Merge two audio files(not concat) in Java(API)?

I need to merge two audio files together. Basically place one audio file on top of another and make one file. I have seen some posts on concatenating two audio files, but none on this. Thanks for any help.

I recommend you take a look at JSyn. I would discourage you to attempt to do it yourself, since it can get complicated with multiple audio formats. It supports a lot more as well.

This worked for me. Use jresources.org to help you. You could use their example: http://www.jsresources.org/examples/MixingAudioInputStream.java.html. For the org.tritonus.share.sampled.TConversionTool package, if you have problems using their library, then download their source code (http://sourceforge.net/projects/tritonus/files/): it's open source, and try using it. I tried it and it worked for me :D. I'm grateful for those guys!
