错误：找不到或加载主类。 Powershell / Java

Question

I just started Java. I was initially using NetBeans to code and it works. But my teacher is insisting that we use a text editor and run it through Powershell. I'm getting a "Could not find or load main class" error with this code.

public class a10{
    public static void main(String[] args){
        System.out.println("Hello World");
    }
}

When I run it on Netbeans, there are no errors, but I'm unable to run it on Powershell. Can someone tell me what's wrong and how I would fix it

Answer 1

I hope you are compiling the class using

javac a10.java and then running it by java a10 --- Is it so
