how can I run java package using the Unix command line?

Question

Given that I have the following file structure,

Anybody know what Unix commands to run the java project or any resources I can look up in order to figure this out?

Answer 1

For compiling both the java files:

EatInTime-SpringBootGrab_Data>javac -d "classes" "src/main/java/DataGrabber/Serial.java"

EatInTime-SpringBootGrab_Data>javac -d "classes" -classpath "src/main/java/DataGrabber/Main.java"

For Executing Main:

EatInTime-SpringBootGrab_Data>java -classpath "classes" main.java.DataGrabber.Main

Hope this helps.
