Using a class from another folder - JAVA

Question

I have a java file with no main (Call.java) with a set of methods. I have another java file that I want to call the constructor in Call.java. Here is the structure: link to file structure

I'm using the command-line to run java programs.

My question is: how can I do so without getting an error

Source code: Class:

import java.util.*;

public class Call{
    private int userTypedInt;
    Scanner userInput = new Scanner(System.in);

    Call(){
        while(true){
            mainMenu();
        }
    }

    public void mainMenu(){
        System.out.println("\n\t\t####| Main Menu |#### \n");
        System.out.println("\t\t0. Exit the program");
        System.out.println("\t\t1. Option");

        // check that the user typed a number - specifically an int 
        try{
            System.out.print("\nEnter a choice: ");
            userTypedInt = userInput.nextInt();
            path(userTypedInt);
        }catch(InputMismatchException e){
            System.out.println("\n\t\tInvalid entry");
            userInput.nextLine(); // clears the buffer
        }
    }

    public void path(int pick){
        switch(pick){
            case 0:
                userInput.close();
                System.exit(0);
                break;
            case 1:
                break;
            default:
                System.out.println("\t\tInvalid Entry");
        }
    }
}

Test file:

public class Test{
    public static void main(String[] args){
        System.out.println("Online");
        new Call();

    }
}
