java.lang.ClassNotFoundException in a simple HelloWorld

Question

I get the message after I try to start "java -cp . "HelloWorld"

Fehler: Hauptklasse .\HelloWorld konnte nicht gefunden oder geladen werden Ursache: java.lang.ClassNotFoundException: /\HelloWorld

It's only a simple programm to check out, if the IDE is runnng correctly.

"to check out if the IDE is running", I have no idea how this is in any way related to an IDE — Stultuske, Feb 12 '22 at 12:21
commandline `java HelloWorld` would have to be run from the same folder `HomeWorld` is located in — J Asgarov, Feb 12 '22 at 12:35
Which IDE? You never say. Where is the HelloWorld.class file? Is it in the CLASSPATH? — duffymo, Feb 12 '22 at 12:46
Exactly what command line are you running? I get this error if I run `java -cp . .\HelloWorld`: note the dot and backslash before `HelloWorld`. — Luke Woodward, Feb 12 '22 at 13:14

I used the Powershell to run the command. Inside of the cmd-Window it runs correctly. Thank you for the extensive help
