How to solve the issue resulting in output of the error message "class not found wrong class name"?

I have the following Java code in a file:

package hello_project;

public class Hello {

    public static void main(String[] args) {
        System.out.println("Hello world");

    }
}

The code works when I run:

java Hello

But the code doesn't work when I use:

javac Hello.java
java Hello

The error message is:

class not found wrong class name

> type Hello.java
package hello_project;
public class Hello {
    public static void main(String[] args) {
        System.out.println("Hello world");
    }
}

> javac -d . Hello.java

> dir hello_project
 ...
