Java packaging issues

Question

Based on java documentation, I've set up my project as such: Source files are in C:\...\sources\com\myname\tictactoe\ And my class files are in C:\...\classes\com\myname\tictactoe\ When I try to run a class (Main.java) in that directory (on powershell) by running "java Main", I get "Error: Could not find or load main class Main Caused by: java.lang.ClassNotFoundException: Main". All my files start with "package com.myname.tictactoe;", and from what I understand that's how they're supposed to be. What am I doing wrong?

what happens when you run `java -cp . com.myname.tictactoe.Main` in the `classes` folder? — f1sh, May 24 '22 at 17:05
have you set the classpath somewhere? If not then check this out .. https://stackoverflow.com/questions/2396493/what-is-a-classpath-and-how-do-i-set-it — Lalit Mehra, May 24 '22 at 17:06

Your java class has a package name so you will not be able to run just java Main. You will need to run java com.myname.tictactoe.Main.

Change directory to C:\...\classes then run

java -cp . com/myname/tictactoe/Main

Worked! Ty. Just had to insert an extra com/ before the myname directory :) – Noam Bechhofer May 24 '22 at 18:20
Yes it should be full package path, I corrected it – Eskandar Abedini May 24 '22 at 18:24
