How do I create a JAR file? The command "jar" in my command prompt is not even recognizable?

Question

All the tutorials I have read simply said to type jar -[options] [jar filename] [files to add].

Problem is, when i go to my command prompt and even type jar, nothing happens..

Do I need to download some kind of tool or add some directory to my command prompt options thing?

Any help is greatly appreciated.

P.S -- I have JRE and tried reinstalling it but still the command "jar" is not recognizable.

Answer 1

jar is usually used when referring to a compressed file in linux. but, in windows you can open a jar file using winrar. search for it on google and download the trial. ive had the 40 day trial installed and working for more than 2 years now.

Answer 2

Check that the jar executable is in your path.

Answer 3

you need the java runtime environment (JRE)
