Oh man , You saved my life , I am facing this issue since more than a week and struggling to solve it , watched tons of youtube videos and stackoverflow solutions, and even after fighting with chatgpt , i was unable to figure out what actually is causing the error , somehow my code was running from "RUN AS JAVA CODE" but it was irritating too do it every time before run, also earlier everything was fine , suddenly after i played with some environment variables i got this issue, and was unable to resolve it . Really really thanks for this help .
Best video! If you cant find the code runner executor map, install code runner and in the settings.json just type code-runner.executormap and the code wiil appear automatically then modify as mentioned in the video
Although the run button works after doing all these but in the terminal when I write javac filename.java and then java filename, I again shows the same error (couldn't find or load main class filename)
Thank you for the video anyway, but... SOLVED ANOTHER WAY: No method solved it for me, either of those presented in this video or in others. The only way for me was: - when compiling, click on the "FIX" option - then click on the "clear cache" option ... and SOLVED !

NoClassDefFoundError In Java Reasons: Java Virtual Machine is not able to find a particular class at runtime which was available at compile time. If a class was present during compile time but not available in java classpath during runtime.

Please look for solution here.... stackoverflow.com/questions/17484764/java-lang-classnotfoundexception-com-mysql-jdbc-driver-in-eclipse Otherwise I'd have to look at your project. You can share your github repo link here.

Where did you find the FIX option ?? @cristianrusso5749
when after opening settings when i press that icon in the corner i am not able to see code runner executor map. why?
You need to install the code runner from the extensions. If that setting isn't there, the copy the setting from here:

please help me l suffer from this
It usually happens when you code in vscode. Change your filename to something else and then compile and run the bytecode. Hope it helps.
code:
package Assignment1;
public class Greeting {
public static void main(String[] args) {
System.out.println("Hello
World");
}
}
Error:
Error: Could not find or load main class Greeting
Caused by: java.lang.NoClassDefFoundError: Assignment1/Greeting (wrong name: Greeting)

My file name is Autocomplete.java but when I initiate javac Autocomplete.jave It keeps popping an error telling me the file is not found. Please what can I do?
Make sure your file is saved in the current folder where you are executing your javac command.
After using java -classpath . Demo
I got output but is there any alternative bcoz i have to do it every time when ever i run java file
Watch the full video, I have explained how to do the same.
i don't have written code runner executer map in my vs code..... what should I do ? plzz tell
You need to install code runner extension from vscode marketplace.
Thanks Man, The first method worked for me
