How to change into an .exe file.

Hi! I would like to know the following:
1. Is it possible to change multiple java files into an .exe file so that you could just click on an icon and run the program.
2. After conversion if you still need a program like Jgrasp to run the written program.
3. What program do I need to covert the files.

Please feel free to explain the proses and the answers when you answer them as this would be MUCH appreciated!:(:)

Read about the creation and manipulation of .jar files; you don't transform a bunch of .class files to an executable .exe file. You can simply double click on a .jar file to run it if you have set it up correctly.

Thanx where can I read up about this? Can't you explain how to do it?

Not really very easy to explain. Also, there are probably quite a few people who distribute jar files that could never do it from the command line, myself among them.

Eclipse can create jar files for you, and most other IDEs probably can, but if you don't have an IDE that can do it, or want to learn how to create JAR files on your own, read through this part of the Oracle Java Tutorials.

There are some tools which can convert jar/java class files into executables. But I didn't see any point to do that, since it's only work in Windows platforms.

Thants Ok because at least people with Windows could use it.:) Can you PLEASE give me the link to the tools??

Realize that those .exe files have to store (almost) the entire jvm and a lot of compiled classes while the jvm itself can compile the byte code in the .class files to machine executable code by its JIT (Just In Time) compiler and its HotSpot mechanism; i.o.w. there is almost no use to transform a bunch of .class files to executable code because the JVM does the same when it runs.

kind regards,

But I want to be able to just click on a icon and then the program must run...or is that what you are explaining to me now?: that it would be the same?

What's the point of bundling jvm in executable. Normally those could leave as pre-request to install the application.

Yep, Launch4j is the one I used in most of the cases when I want to build an executable, which I hate to do. ;)

haha LOL...Why do you hate to do it? I have the program now, but have no idea of how to operate it. I'm not sure if you can use a .java file? Whats the steps to do this operation?

Java file, you cannot distribute as it is. Because then you've to compile it before run on clients' end. So the client has to install JDK version which compatible to compile your Java class, and waste some space of his/her HDD. Deploy it as a jar package or a executable (which I'm not recommended).

Do you know how to deploy JAR packages?
