How to call jar class

How to call JAR CLASS with CMD

I am a newcomer to java.

This is my JAR file

https://drive.google.com/file/d/16bL0n4KS9IP75tDJhhbeNLeiS3boX3iP/view?usp=sharing

I want to use CMD to call the CLASS inside JAR.

I tried to call getHardware()

java -cp uhfrcom13_v1.9.jar com.handheld.uhfr.UHFRManager.getHardware

I got the error

The main method is not found, define the main method as: public static void main(String[] args) Otherwise the JavaFX application class must extend javafx. The application class must extend javafx.application.Application

Please master teach me how to call

Make the following changes and it will work.

  1. Make sure to have a main method (public static void main (String [] args)) in your class where getHardware is a method, then call your getHardware method to work on from the main method [you should call the class from CMD and not the specific method!!].
  2. Make sure to use the following command, in CMD, assuming your class is UHFRManager and getHardware is a method inside it,
    java -cp "uhfrcom13_v1.9.jar" com.handheld.uhfr.UHFRManager
    I hope it works.

In UHFRManager class you have to add public static void main(String[] args) - in this method you can call your getHardware() method. When running jar file, java is always looking for main method in your class.
