Hello,
some of my Friends, and I decided to make a Media player using Java just for the fun of it. here are my Questions,
#1: is it possible using Java ? or should I use a different language?
#2: the process of Reading||Displaying||Viewing Video files is called ?
#3: any good resources to learn from ?
Thank you.

Hope it helps.
This is the simple code for playing single file enhance this code for playing more file replay if it is helpful to you though i know the code for playing more than 1 file but you can do it your self practice makes man perfect. good luck.

}I didn't ask for the code , thats what "I and my friends" Should do =\ thanks for the spoiler , but I guess the Q#1 A is "yes"
asd for Q#2&Q#3 I need those keywords to search more about the process of how a video|movie works :)
Thanks for that!
Hello Skwatamkar!
I'm looking for a java MIDI player. What I need is a source code and a complete program, which is created in Netbeans or another program. I should create a JFrame form and grafically program the MIDI player.
Can you help me in this problem, because I didn't find any sourse code over the internet which is created using JFrame form.
Thank you, Gabesz
