    You can put all the class files and other resources the program needs in a single jar file.
    I use the jar command (part of the JDK) to build and update jar files.
    If you don't understand my answer, don't ignore it, ask a question.

    Even though it doesn't involve actually converting a jar to an executable format, programs such as AdvanceInstaller do offer nifty tools for packing your jars and resources and installing them to a default directory, be it in AppData or with other program files and then providing a shortcut to your jar in the start menu.

    I use the jar command from a batch file. See the doc for the syntax of the command.
    Here is one of the batch files:
    @Rem Create the SlideShowApp.jar file for standalone usage:
    %DEV_DRIVE%
    cd %DEV_HOME%\JavaDevelopment\SlideShow\
    jar -cmf SlideShow.mnf %JAVA_RUN%\SlideShowApp.jar ImgIdxEditor.html
    @REM
    @REM Now go get the tools we need
    @REM
    cd %DEV_HOME%\JavaDevelopment\
    jar -uf %JAVA_RUN%\SlideShowApp.jar SlideShow\*.class NormsTools\GetInput*.class NormsTools\GetIntInput*.class NormsTools\ShowMsgBox*.class NormsTools\MessageArea*.class NormsTools\ChoiceOfYesOrNo*.class NormsTools\ErrDialog*.class NormsTools\MakeEnterDoAction*.class NormsTools\Sorter*.class NormsTools\ArrayUtil*.class NormsTools\FindOurHome.class NormsTools\ShowListBox*.class NormsTools\SaveStdOutput*.class NormsTools\DroppedFileHandlerN*.class NormsTools\NormsDropTarget*.class NormsTools\OrderingList*.class NormsTools\DroppedFileHandler*.class NormsTools\AskMultipleChoices*.class NormsTools\GetPastes*.class
    @REM Done
    @Echo
    @Echo Created: %JAVA_RUN%\SlideShowApp.jar
    @Echo
    @Echo Remember to copy jar file to C:\My_Photos when tested!

    Find the doc for the jar command. It is part of the Java SDK.
    Read the doc and look at the sample batch file I posted that uses the jar command.
    %DEV_DRIVE% is one of several environment variables I use to define paths to folders on my PC.

    Do you want to run Java without a JVM? As far as I know, in order for a Java program to run it needs a JVM, even if it's in exe form. Take the Eclipse IDE as an example. It has an .exe version in Windows and a local-binary executable for Linux (there's no application extension in Linux). However, this is just a "dummy program" which runs Java similar to how a batch file or command script would by starting the JVM and running a jar file. Eclipse will not function without an installed JVM.

    The only way to technically run Java without a JVM is on specialized hardware which would treat Java Bytecode as assembly code. I think such hardware exists on some mobile devices, but I'm not positive as many times it's just a JVM ported over to another hardware architecture (for example Android).

    If you want a native application, best to start out with a natively implemented language like C or C++. For Java applications you're likely better off sticking with JAR files, web-start apps, and applets.
