The jar command cannot be found

Question

Command Prompt gives me this output('jar' is not recognized as an internal or external command, operable program or batch file.) when I enter the command 'jar'. I have installed the Java Development Kit 16 and I have set my JAVA_HOME Variable. java -version works! Why does it not work?

because `jar` is not a command. You need to use it with `java -jar ` — Jude Niroshan, Apr 16 '21 at 16:46
@Jude Niroshan, `jar` is the command to create jar file. It is provided with the JDK (not JRE). — Stéphane Millien, Apr 16 '21 at 16:50

You have to update your PATH environment variable, add:

Windows : ...;%JAVA_HOME%\bin
Linux : ...:${JAVA_HOME}/bin

With Linux, you can also have a look to update-java-alternatives or update-alternatives.
This will create symbolic links to your JDK binaries.
See: How to use the command update-alternatives --config java
