There are basically many ways to convert your Java source file (.java) or Java class file(.class) into an executable program (means double clicking then run or click+return) for windows.

By the way, I use exe4j and jar2exe ;)

One of these ways is by using a software that will convert your source codes into .exe file.
Example of converters you can use:

1. JSmooth
Download: CLICK HERE (sourceforge)


2. Launch4j
Download: CLICK HERE (sourceforge)

3. JexePack

4. exe4j
exe4j is a Java exe maker that helps you integrate your Java applications into the Windows operating environment, whether they are service, GUI or command line applications.

Download: CLICK HERE

5. jartoExe1.8
Jar2Exe is a tool to convert jar files into exe files.

Download: CLICK HERE

Example:
Let us convert this java code to .exe program



OUTPUT (in exe):



Please note that you have to locate your JAR file generated by your IDE/JAVA compiler.
In netbeans, right click the project > properties > Packaging > check the "compress jar file".
Jar file will be under your Dist folder.

(3PM, no lunch yet :( damn Java, I almost forgot how to wrap jar to .exe )
