Solved in 2 steps
- Step1-Study the scenario below and create a Java Program for Builders Warehouse, The program must consist of a class called Materials to handle the details of the materials. The program should read the materials details from the material.txt file then use a LinkedList to store the material details. Then finally the products stored in the LinkedList must be displayed like the sample code below step 2-There must be clear code and a screenshot of the code running.we are going to design a system to Manage loans from the local public library For this we will need the following entities, plus collections for each of theentities: Patrons, Books and Loans The data for a Book will contain at least the following:AuthorTitleISBN NumberLibrary ID numberCostCurrent Status (In, Out, Repair, Lost) You may add other data needed for your implementation as well as you will need accessor and mutator functions for the data.The data for a Patron will contain at least:Name (e.g. Fred Smith)ID number (6 digits e.g. 123456)Fine BalanceCurrent # of books outYou may add other data needed for your implementation as well as you will need accessor and mutator functions for the data.

For the…Question 6 Which pattern would you use in the following situation: You have a collection class that offers the ability to filter the collection, but since there are so many properties we could filter on, we want to maintain flexibility and not hard-code what property we filter on; rather we want to allow client code to specify what to filter on. 1) State 2) Strategy 3) Observer Question 7 Which pattern would you use in the following situation: You have multiple components that need to react to events in their own way, and you have components that do not care about these events. 1) Observer 2) Strategy 3) State
- In Java programming What is the difference between a static data member and an instance data member? Declare a unique class (i.e., different from a classmate's posting) that contains an instance data member and a static data member (in the same class).

The database stores information about houses, each with a house ID, address, and zip code. The database stores information about person, including person ID, house ID where the person lives, person name, phone number, and status where 1 means currently tested positive (i.e., the most recent test result is positive), 0 means currently tested negative (i.e., the most recent test result is negative), and null (no test so far so status is unknown). The database stores information about a person's all past tests, including person ID, test date, and result (1 means positive and 0 negative). The database stores information about events (could be gathering, party, etc.). Each event has an event ID, event name, date, and address. The database stores information about a person participated in an event. The database stores information about flights, including flight ID, flight date, flight number (a…Class field corruption must be prevented.

Identify and display any backend frameworks used by the person. Output the frontend frameworks the person is familiar with. Create a list of mobile frameworks the person is interested in.

Check if the person uses continuous integration and display the corresponding message.Generate use cases based on the folowing scenario. Chillax Video Store (CVS) runs a chain of video rental stores. Before a video can be put on the shelf for rent, it must be catalogued and entered into the video database. Every customer must have a valid CVS customer card in order to rent a video. Customers rent videos for five days at a time. Every time a customer rents a video, the system must ensure that this customer does not have any overdue videos. If so, the overdue videos must be returned and an overdue fee paid before the customer can rent more videos. Likewise, if the customer has returned overdue videos, but has not paid the overdue fee, the fee must be paid before new videos can be rented. Every morning, the store manager prints a report that lists overdue videos. If a video is returned in damaged condition, the manager removes it from the video database and may sometimes charge the customer.Encapsulation in Java Implement getters and setters for the class in the code editor.
