I 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 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.
What I want to do is very clear, just play sound and pause it. The problem is that I can't pause the music. When I click the pause button music keeps playing .I have been working on for 2 hours. I can't find the mistake; what am I doing wrong?
public class MainC extends JFrame implements Runnable,ActionListener { private JPanel contentPane; private JTextField txtname; JButton btnopen; JButton btnSave; JButton btnplay;
How to insert and play a video or a music background in a java application. Let me explain better... I need to develop a game where sometime I need to show picture, or play videos and also, if is possible, add a music in background... I work with eclipse and I know quite good the main concept of java's language...
I am writing a java application that can play youtube video by given URL. first i tried with JPaneleditor, then now i am trying google youtube api, but maybe api is abit too tough for me.
In my card game applet I have to play some music and the user must have the ability to play, stop and pause the song using buttons. I got the play and stop to work easy but I'm unable to add the pause option/method.
I have made a program on BlueJ but need to transfer the class to a pen drive so that I can take it to school and show it to my teacher. How is this done
I have a batch of files that I want to remove a common word from all of their filenames. I think I could bash my way through this if I had a linux machine, but I don't. Any tips on what classes I need for the files I want to rename (if any) would be great. I can handle the string changes, but searching a directory and renaming files is something I've never done with code before.
My 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.
I'v tried everything, i'v tried to create new path in enviornment variables i tried adding this path -->(C:Program FilesJavajdk1.8.0_20bin) to the end of the default path doesnt work i uninstalled and reinstalled and did the same thing over and it didnt work am i editing the files wrong ? what i do is write the hello world program in eclipse to make sure there arent any errors then copy and paste in note pad++ save it as a .java file and it doesnt work i tried save it in regular notepad as .java laso and it doesnt work iv done every thing i could possibly find on youtube is this stuff outdated ? is there a new way? this one one of the errors ill get
C:javat>javac helloworld.java helloworld.java:1: error: '{' exp public class helloworld.java { ^
And this is the code for that file im trying to compile
public class helloworld.java { public static void main (String args[]){ System.out.println("hello world"); } }
I am a begMy task is to write a program that plays the "Hi Lo guessing game." The program runs smoothly. However, it does not proceed to the next game after the previous game is done. I need to add a "play again" choice to the program so that the user will continue to play until they have chosen to quit. I have tried several different ways but each one has failed. I am completely stuck on this. I have attached my code to this.
So, after my graphics card melted down, I decided to use a chat program because I can't play the game server which I am staff on. I've downloaded this:
CactusChat: MC 1.7.4 - 1.7.5 chat client for Windows, Mac and Linux Operating Systems | EcoCityCraft Economy | Minecraft Servers
After I knew it was a .jar file, it would basically fail, I would launch it, it turns into a cmd for 0.5 seconds, and closes without any progress. Typical, and expected.I downloaded the latest java update, removed 3 older versions, and now my Java SE Binary program went missing. I can't even launch it, and it tells me to look for another program to launch it with.
I have seen different methods of creating and reading files (specifically text files) in Java. The PrintWriter method or the Formatter with a Scanner to read the file, using a BufferedWriter with a BufferedReader, etc. They will all read/write text files, but from what I understand they do so in different ways. When would it be more beneficial to use a buffered writer than, say, PrintWriter, which is much simpler code-wise? Is there a "best" way to handle i/o in general in Java?
I'm doing a little game in Java and I would like to insert a background music managed by a JButton. When the button is pressed, the music starts and then, to stop it, the button is pressed again. If you don't press the button to stop the music remains in the loop until the player plays.
my course material is due for term 1 of my cert 4 programming course, but My lecture will not pass my java projects because there is no source files generated for them in the net beans project structure, tried building, cleaning and building, all i can think of?, tried IDE's 7.4 and 8.0 .
I'm new to JSP, and am trying to follow along with a textbook in which we look at the differences between JSP files and the java files created from them. I'm using Tomcat and IntelliJ IDEA, both recent versions. Whenever I compile my project (which is just downloaded code from the textbook) everything works fine, I get accurate results in my browser. The problem is I can't for the life of me find the .java files that are supposedly created. It seems like they're supposed to be in the tomcat directory but they aren't, and I can't find them anywhere else and am coming up empty on windows search. So I'm thinking the files are getting deleted. So how would I stop this from happening?
**Here is my question. I'm trying to use input and loop method to search for a file. The above code works but my problem is lets say I try to find 2 different text files**
1. billing-20140527[09].txt has
a)XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. b)XGMS,2034-05-27 30:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
2. billing-20140527[10].txt has
a)XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. b)HELO
I try to find the number 1 in both text files, if lets say I input the text file name is billing, I can find the number 1 in both text file and output them:
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. B)/> XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
However, if I specify the text file name: billing-20140527[09].txt and find the number 1 inside the text file, it will only output:
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
How can I do so? Because I can output the number 1 from both text files even though I specify the name.
have to create a file named Lab13.txt. In the file I have 10 random numbers. I have to import the 10 numbers and have to Multiply all the numbers from Lab13.txt by 10 and save all the new numbers a new file named Lab13_scale.txt. so if the number 10 is in lab13.txt it prints 100 to Lab13_scale.txt. how do i get it to Multiply Here is what I have:
I made a tiny app that saves notes to a folder within the classes directory where I created the .jar file.Let's say I wanted to add this to Java Web Start. Would I be able to transfer the jar file within a folder(s) or would I have to change the program so that It creates a new folder to save texts In automatically ? Basically , can jar files be transferred with other files/folders ?
Using Eclipse I have imported a WAR with source. I have exported that project as a new war and it ran fine. I then added my own package and exported the war again. The jar file does not show up in /WEB-INF/lib folder. When I deploy the war on a tomcat server it barfs the following error:
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.sharpline.fields.form.fields.TextAreaFormType] for bean with name 'com.sharpline.fields.form.fields.TextAreaFormType#53c37' defined in ServletContext resource [WEB-INF/activiti-standalone-context.xml]; nested exception is java.lang.ClassNotFoundException:
[Code] .....
It looks to me like my class (jar) is missing in the final war. How do I resolve this?
I recently started working with Java 8. I have been doing Java development on and off since the early 1990's. Most recently I have been doing all my current work in Java 6. I decided to "take the plunge" and to start getting involved with Java 8. I have an imaging application for geologic research I started working on in Java 6 and Swing, and I am now continuing that development under Java 8. It was a pleasant surprise that to find that all of my code built without any changes (I'm using Eclipse Luna and just deleted the Java 6 runtime and added the Java 8 runtime after downloading it). The application launches fine from inside Eclipse.
However I ran into a problem when exporting the application from Eclipse to a runnable JAR file and then trying to launch it. After creating the runnable JAR I was not able to launch it by simply double clicking. A command line box would open for a second, then close and the application window would never open. To upgrade from Java 6 to Java 8 I only downloaded the Java 8 runtime environment, not the Java 8 JDK. I am working in Windows 7 and tried updating the JAR file associations and experimented with various path entries in my environment variables. No mater what I did I could not simply double click the runnable JAR to launch it.
Then I deleted all my Java downloads and started over. This time all I did was downloaded the Java 8 JDK and installed it. I then pointed Eclipse to the Java 8 runtime environment that was installed with the Java 8 JDK. My code built and executed perfectly in the Eclipse environment. Then I exported the the Eclipse project as a runnable JAR again and tried to launch it. This time it worked as expected. Double clicking the runnable JAR launched the application!
So my question is if I want to give this application to someone to run (i.e. deploy it) that is not a developer, do I have to have them install the Java 8 JDK? I assumed that all someone would need to run the application as a runnable JAR is the Java 8 runtime environment, not the JDK. However, when I had only the Java 8 runtime environment installed I could not launch the runnable JAR. With the Java 8 JDK I was able to run the runnable JAR as expected, with no problem.
im trying to play a sound when button is clicked. here is the following code
InputStream in; try { in = new FileInputStream(new File("failure1.wav")); AudioStream audios = new AudioStream(in); AudioPlayer.player.start(audios); } catch (Exception e) { }
just wondering why it does load;
i do get the warning
warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioPlayer is internal proprietary API and may be removed in a future release AudioPlayer.player.start(audios);
