I am followint the guidelines for compiling my program in java, but keep getting the error message that package com.phidget22 does not exist
- my app, as well as phidgets22.jar are located in the same folder
- When I use the command 'java -classpath .:phidget22.jar Train.java' I get an error message stating " package com.phidget22 does not exist
import com.phidget22.*;"
- When I use the command 'java -classpath .:phidget21.jar Train.java' I get an error message stating " Could not find or load main class Train.java"
here is my code (please note that I have had to replace . in two places with (dot):
