How to create a [JAR](https://www.mindstick.com/forum/159220/how-can-i-create-an-executable-runnable-jar-with-dependencies-using-maven) [file](https://www.mindstick.com/articles/59/encrypting-and-decrypting-files-using-c-sharp) in [Command Prompt](https://answers.mindstick.com/qa/51716/how-to-make-bootable-pendrive-using-cmd-windows-command-prompt):

· Start Command Prompt.

Navigate to the folder that holds your [class](https://www.mindstick.com/blog/165/generic-class-in-c-sharp) [files](https://www.mindstick.com/articles/23302/the-importance-and-advantage-of-keeping-your-important-files-on-the-cloud);

· Create a Manifest file and your Jar file;\
C:\mywork> echo main-Class: Hello >manfest.txt\
C:\mywork> jar cvfm Hello.jar manifest.txt HelloWorld.class\
or \
C:\mywork> jar cvfe Hello.jar Hello HelloWorld.class

This will create your manifest and jar file in the location where your java program is.

· Test your jar directly by typing the following command on your command prompt or simply double click the Hello.jar file from where it is saved.

C:\mywork> Hello.jar

or

C:\mywork> java –jar Hello.jar

This will run your java program using JAR file.
