I created simple java project by using Intellij and it works in both command prompt and intellij as well. here is the code:

public class HelloWorld {
    public static void main(String[]args){

        System.out.println("Hello World!");
    }
}

Then I created a package and moved main class into it and it works in intellij but not in command prompt.my codes are,

package com.attempt;

public class HelloWorld {
    public static void main(String[]args){

        System.out.println("Hello World!");
    }
}

this is what appears in command prompt:

    For example, [this general Google search](https://www.google.com/search?q=java+classnotfoundexception) and [this Stack Overflow site-specific search](https://www.google.com/search?q=java+classnotfoundexception+site:stackoverflow.com) should get you well started at taking a stab at solving this. – Hovercraft Full Of Eels Mar 31 '20 at 19:11
