This activity has the purpose of helping students to design proper hashing strategies. (Objective 3).
Students Instructions:
After studying this module, write the answer to the following programming assignments in a text file and
submit them as an attached Word doc or PDF through the provided link in Blackboard. The deadline for
submitting this assignment is indicated on "Tools", which is located in "Calendar" in the "Blackboard"
platform. You will have two (2) attempt to send your answers by Assignment link before the deadline and
the last submission would be considered as your final solution. This exercise has
Implement a dictionary by using hashing and separate chaining. Question:

The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction.
The schema for the database is also depicted.

Choose one of the applications above. Project logic is completely up to you. However, your application is supposed to include at least 3 different windows, in other words, 3 JFrames and you should create connections between those frames according to the logic of your application. Those JFrames can be accompanied by normal (model) java classes as well. In your application, file writing and file reading methods should be utilized. When submitting your project, you are required to have following parts in your paper; • A general description of the application. • Brief explanation of the logic of using different components in the application. • Screenshots of all possible windows. • Source codes (Showing each class separately).arrow_forwardGenerics enable you to specify the exact type that will be stored in a collection and give you the benefits of compile-time type checking—the compiler issues error messages if you use inappropriate types in your collections.
