Add the code that works with the array of product data

1. In the ProductDB class, add code that implements the getProductByIndex method. Read the data for the three columns based on the row index value, i. Use the Product class constructor to create an object for the row using these three values retrieved from the array. Return the Product object that was just created 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 a loop to search all rows of the array. Inside of the loop use an if statement to find a row that matches the input product code parameter. Use the Product class constructor to create an object for this row that has a product 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 a loop to get all rows in the array. 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.

	Column Index
Row Index	0	1	2
0	"java"	"Murach's Java Programming"	"57.50"
1	"jsp"	"Murach's Java Servlets and JSP"	"57.50"
2	"mysql"	"Murach's MySQL"	"54.50"
