Create a .jar file

To create a .jar from class files, navigate to the folder containing your class file and run this command:

jar -cf <MyJar.jar> *.class

Make sure the path to jar.exe is part of the system path variable. Alternatively, specify the full path to jar which can be found under /bin in the JDK folder. For example:

C:\Users\MyUser\Desktop\jdk1.8.0_201\bin\jar -cf <MyJar.jar> *.class
