I want to develope an application which extracts data from another application (the "whatsapp" application) when i am getting an incoming call.
How can I do it?
Maybe relevant guids will help :)
Thanks in advance!
Yogo.
It is generally not possible, unless if the application makes it public, for instance, sharing data via Intent or storing files in a public folder, e.g. in the SDCard.

I am writing one web page in which I am putting one html input type="textarea" in which user will write their java code and on submit it will return output of that java code. Can I do this using jsp? if not then what are the other ways.
I would think very carefully before allowing people to do that.
At the very least, to read and run the user's input, you will need a JDK to compile it, and a JVM to run it. Since you're talking about over the web, presumably the user's machine will not have those (otherwise they'd just use theirs), so you'd have to use the ones on your server - that is, take the user's text, upload it as a .java file to your server, compile and run it (for an anonymous user on your server!), and send the result back to the browser session.
As you can see, there are a couple of pretty big, bad security problems here. Not recommended !

I have a HTML file that acts like a template. For example:
Dear Name Surname
is contained in a HTML file. At runtime I would like to replace this with Dear Someone Name. How is this possible in Java?
Having looked in Google I couldn't find anything. I know I can do this in XML, but in this scenario I have to use the above approach.
Depending on the degree of complexity of your file a simple String.replace() or String.replaceAll() might do.
If you have more complex files I would recommend templating engines like Velocity or Freemarker.

Can I play 2 sound-files simultaneously?
I can handle the loading, changing loudness, opening and closing of one file.
How can I load 2 files in separate frames and start the playing with simultaneously hearing.
Put the opening and the playing into two separate threads, then start them. The two threads can be synchronized so the playback starts synchronously.
