Add the code that works with the array of product data- In Java NetBeans

1. In the ProductDB class, add code that implements the getProductByIndex method. Use the Product class constructor to create an object for the row with index i. Return the Product object for the product data at the specified index.
2. In the Main class, add code that uses the getProductByIndex method and displays the data thats returned by it.
3. Run the application and make sure it works correctly. At this point, it should print data for the PRODUCT BY INDEX heading.
4. In the ProductDB class, add code that implements the getProductByCode method. Use the Product class constructor to create an object for the row that has a code matching the input parameter. Return the Product object for the product data with the specified code.
5. In the Main class, add code that uses the getProductByCode method and displays the data thats returned by it.
6. Run the application and make sure it works correctly. At this point, it should print data for the PRODUCT BY CODE heading.
7. In the ProductDB class, add code that implements the getAllProducts method. Use the Product class constructor to create the objects. This should return an array of Product objects for all of the product data.
8. In the Main class, add code that uses the getAllProducts method and displays the data thats returned by it. To do that, youll need to loop through the array of Product objects thats returned.
9. Run the application and make sure it works correctly. At this point, it should print data for the LIST OF ALL PRODUCTS heading.
