Error: Could not find or load main class Check.java

Question

I have Check class in my ua.kiev.prog package.

It is Checkclass :

package main.java.ua.kiev.prog;
public class Check {
public static void main(String[] args) {
    System.out.println("Hello world");}
}

I need to run program from console and I am trying in console :

C:\PROJECTS FOR FOXMINDED\CHECK\src\main\java\ua\kiev\prog>javac Check.java

And when I am trying to run :

C:\PROJECTS FOR FOXMINDED\CHECK\src\main\java\ua\kiev\prog>java Check.java
Error: Could not find or load main class Check.java

In my system variables I have :

CLASSPATH : D:\Java\jdk1.8.0_202\lib

PATH : D:\Java\jdk1.8.0_202\bin

Appreciate for each help!

The (qualified) name of your class is main.java.ua.kiev.prog.Check, not Check.java, so use java main.java.ua.kiev.prog.Check instead. The java command doesn't and cannot do anything with source files.

Make sure you're running from C:\PROJECTS FOR FOXMINDED\CHECK\src

I tried `java Check` , it has the same error – user13566239 May 19 '20 at 19:58
@user13566239 I updated it - I forgot that your class was inside a package. You must use the qualified name to run it. – user May 19 '20 at 20:44
`java main.java.ua.kiev.prog.Check`also doesn't work and has the same error – user13566239 May 20 '20 at 06:56
cd to `C:\PROJECTS FOR FOXMINDED\CHECK\src` and run from there – user May 20 '20 at 16:59
