I am having problems getting my program to compile and run. Newbie from the word go. The main problem is I have all of the code but I cannot make the other classes go with the main class. Any help would be great.
Here is the code that I have and it only returns the movies class

public class Movies {



    /**
     * @param args
     *///main method
    public static void main(String args[]) {

        new Movies();

        // This program will track DVD movies with number in stock, name of DVD,
        // price of Dvd and the total value of inventory

        /**
         * Constructor for objects of class GBInventory
         */

        {
            new java.util.Scanner(System.in);

            for (int i = 0; i < 4; i++) {

                System.out.println("Product Title is " + dvd[i].getDvdTitle());

Please use

tags around your code.

Are you putting all the classes in one file? Java requires that each file contains only one class. I hope that it helps.

In your method main(), why are you doing new Movies(); and new java.util.Scanner(System.in); without affecting their return values to a variable of the same type?

I think that a class is by default private, so it may cause problems if you want to instantiate this class for an object. It is better to append "public" before "class" in your DVDMovies class. Also in the end of that class, you are putting a println out of nowhere and it will be never called.

Be careful, you have two DVD classes!

I doubt that you are the writer of that code...

I am using eclipse and whenever it gives me a red line then it gives options to fix it and I just keep picking options to get rid of the lines that is what there is so much code. I have four different classes
movies.java, inventory.java,product.java, dvd.java and I need to know how to make them all work together because i have a main method in the movies.java but do not know how to get the other classes to fall in line so to speak
