You should prepare TWO videos, one to demo the execution and the other to answer the requested questions and submit video

If you are working in a group, then a video record of collaboration is must otherwise NO grade will be awarded.

Problem: (15 points) Develop an application to manage the product details using a binary file. Your application should save the information of each field of the product using binary format and each record should be of the same size.

Possible operations and sample GUI is provided for your reference.
