I wanted to build an mp3 player as a Java project. One crucial part of the project involves being able to play an mp3 fie. I am not able to find the right api (if one exists) and am not able to find a suitable answer when searching on the web. A simple code snippet illustrating the playing of mp3 file using Java program. Also, I am using Eclipse IDE and how to import files if any importing of files is required.
View RepliesI was looking at the Sound API pages in the java tutorials. I was planning to use it to run wma files. Fortunately, for me, I found, soon into the tutorials, that these API DON'T support the type I have all of my files in (I have a ton of wma files but none of the libraries mentioned support them.)
I almost thought I heard JavaFx or whatever it's called does, but that sounds foreign and Netbeans lists it as a separate type of java in a way, so I don't know if it would be cross-platform or if it could work with the JavaSE API.) Nor do I know what JavaSX or whatever it's called is really, other than that it's more for internet than application.
If I wanted a JPanel or Applet acting as the content pane of a JFrame or being in a JFrame, could I use JavaFX (or whatever it's called) or some third party library (that I always tend to end up spending hours on trying to get it to find the jar files when I import them, so I hope I don't need too many jar files!!!! ) would it work with the JavaSE API?
I don't know much about Java and playing sounds (other than that there is a static method, I think under Toolkit, that will play a system beep) with programs.
However, I can see that that packages don't support certain types (so much for cross-platform!!!!!!! ) and also that a while back that Oracle took over and that they aren't really updating the Java Sound APIs really that much at all
So, without having to learn a whole new Java set of standards (assuming JavaFX or whatever it's called is a different set of standards from JavaSE), is there a way to play .wma?
That's all I seem to have on my computer.
(I suppose I could create new sounds, though if Oracle isn't updating the library, who knows if even that works anymore, but if you're trying to run a Java Media Player that runs lots of DIFFERENT sound file types, this seems a real setback. )
I heard you could convert them to MP3s (I heard there were free things that did it, but who knows if the things aren't filled with viruses that'll do it or, even if they're not, that they'll really mess up the quality of the sound and that I might lose the old .wma file in the process even if it doesn't corrupt the sound.)
But, even if I get a .mp3, I heard the main JavaSE libraries DON'T cover that either, though it was said it was easier to make it run them than .wma files.
MediaPlayer and the main JavaSE classes don't seem to be able to fit for this type of program (a java media player) that I was planning. Heck, they can't even play any music I have on my computer at all, media player or not.
I am downloading around 50 PDF files programmatically using Java program(like a servlet service) one after another in for loop.

View Replies View RelatedI am quite new to Java. I have downloaded a tictac example Java applet code and I run it on Eclipse with no problems. But when I try to test it outside Eclipse by doing the following:
I copy the .class file and two gif-images to another location and call the Java from html code:
<applet code="hello/HelloWorld.class" WIDTH="300" HEIGHT="300">
And I put the two gif-files to hello/images folder. I get and an error:
AccessControlException
access denied ("java.io.FilePermission")
"I:ImportantProgrammingWebProgramminghelloim ages
ot.gif" "read")
The path seems to be correct. I load the pictures from the Java code by:
notImage = getImage(getCodeBase(), "http://www.javaprogrammingforums.com/images/not.gif");
If I draw (drawLine) the X and O instead of using gif, then it works.... so its really the gif-loading which is the problem.

I am trying to compile multiple jar files into one jar file from inside a java program. I know how to do this with shell scripts but I would rather have a universal application than one that will only run on Mac, Windows, or Linux. This is my current compiler code:
if(System.getProperty() == "Mac OS X"){
Runtime.getRuntime().exec("javac -classpath jar1.jar; jar2.jar");
}
I would then continue this on for Linux and Windows, but this limits my application.

So I am trying to write the output of two different java class files to one txt file while the program runs. The file name is determined before the program is ran, through the command prompt as arguments. How can I get the second class file to edit the same txt file without running into compile errors.
For right now I'm just going to send everything that the second file outputs to a message String variable, so that the Main class outputs to the the text file. I still want to learn how to write to the same text file directly from the second class file.
import java.io.*;
public class Test{
public static void main(String[] args) throws IOException{

I'm supposed to write a computer based testing program using files. I have started writing however, I am stuck. I am to prompt the user to enter the file name 'test.dat" and if something different is entered then a error message should be displayed. Also the file will create an input stream for the data using the file. I am to have the user enter other information about an employee and then write the record to the file.
The program should be created so when the user enters "quit" the loop is terminated and the file is closed. I'm not asking for code. I was just giving a brief synopsis of the project. Where I am stuck is I wrote the first part of the program that creates the file; however when I enter a wrong file name the exception error message does not display. The code is below:
import java.io.*;
import java.lang.*;
import java.util.*;
public class Project5Write

View Replies View RelatedMy friend has a youtube channel with 50.000 - 100.000 subscribers. I dont know the exact amount but he asked me to make a program for his subscribers. I made it in Java and it works perfectly fine but now i want to make it secure so people can't decompile it and read/change the code. Because ofcourse he also has viewers who can hack programs.
But i dont know how i can do that. I dont want to make the code hard to read. I already heard about program which adds lines of code without doing anything actually and programs making the code a lot more complicated. But thats not what i want, i want to make the Class files undecompilable so people cant decompile it to Java files again and read the code.
I know this is possible, Runescape for example is written in Java too and secured good enough in my opinion. I know there are fake Runescape games called private servers or something like that. But its not easy as downloading the game, decompiling it, connecting it to another server and you're done. A little kid can do that but i think its even possible that people just programmed Runescape again from scratch.So i want to make my program very hard to decompile or even impossible, i want it as impossible as possible.
