This site is not a code writing service. We will help you to help yourself, but we will not complete your work assignment.

I suggest that you either learn what the errors are about that Checkmarx raises. An alternative is to consult with your superior that they did not teach you appropriately for the work task they assigned to you. Maybe you want to hire a consultant or maybe Checkmarx provides hints as to what the problem is, or how to solve it.
