How to open or run a JAR file on Windows

Since Java files can’t run on Windows on its own, you need to install the Java Framework or what is popularly called as Java. That said, Java files can be dependent on a particular version of Java. You will need to take care of that as well.
While Archiver tools like 7-Zip can extract content from JAR files, but doing that is pointless – we need to execute the files just as we run the EXE files.
