Conversion of .class to jar and .class to exe

Question

How do I convert:

• class file to jar file using cmd?
• class file to exe file?
• jar file to exe?

Can I convert exe file to jar file?

Answer 1

To convert (actually, package) .class files into .jar files, you use the jar tool. You can then generate a .exe file from the .jar using tools like Launch4j, JSmooth or several other packages (search the web for "jar exe").
