Create an application to record student courses and grades. The application should also print a student's transcript. There are four programmer-defined classes in the application: Course – record student name, course title, credit and final grade. Transcript – create a collection o Course to perform record adding, deleting, sorting, searching, and printing operations. You may use any class in the Java collections.Validator – verify data entries of the credit (no letter or negative number) and final grade (must be a valid letter grade; you may reuse the Validator class coded before).

Provide a function named "addToSessionStorage" that accepts two parameters: The first parameter "storeName" is the store name for your session storage. The second parameter "objName" is an object. Inside the function, use sessionStorage to save "objName" under the store name. Your test object can contain any properties you want.Hint: Use JSON methods on these storage problems. Note: The remaining buttons and paragraphs do not have id attributes. You will need to construct selectors to meet these challenges.
you are required to read input file containing data of countries or region, to compute and display the data in decreasing order, and some statistics in an output file. Structure of input file: The first two lines of input files contains the region information, date of taken data, and heading of the records. Each line of the rest in the input file contains country name, confirmed and death total cases. COVID_19_data class: used to store records from input file. You should provide generic methods to compute average of confirmed cases, to sort list in descending order using selection sortii , and any additional method(s) to solve the problem. Tester Class: your main method should class two methods to read the data and to display the result as shown below. Your class should be user friendly and control any unchecked errors
Write a program that connects to a database, creates a Moviestable (if it does not already exist), and provides the user the ability to manage a movie listing database. The database shouldinclude fields for a movie’s name, run-time, rating code, date ofrelease, and two primary stars. The user should be able to enternew movie information, delete existing movies, and obtain a listof movies in the database.

You are asked to create a Java application called CafeInfoSystem.java. The application can read records in the database and display the menu. A sample run of the program is as follows: Welcome to DEF Cafe Here is the menu: - Latte: $5.0(L)/$4.45(M)/$3.7(S) - Americano: $4.1(L)/$3.5(M)/$2.95(S) - Cappuccino: $5.0(L)/$4.55(M)/$3.7(S) - Caramel Macchiato: $5.0(L)/$4.5(M)/$3.75(S) - Mocha: $6.0(L)/$5.4(M)/$4.5(S)
This is sample data from my JSON file: "firstName" : "Juan","middleName" : "Dela""lastName" : "Cruz","username" : "JuanDelaCruz","password" : "1234", I already have a JAVA GUI that displays the data of each user in a table format. I need the part of my program that will allow the server to either accept or reject the user. If the user is accepted, the credentials of the user will be saved in another JSON file. If rejected, the server will do nothing.
You need to design this class. It’ll hold all the FoodWastageRecord objects in memory (notice the has-a relationship between the FoodWastageTracker class and FoodWastageRecord class in the diagram above). It’ll allow the user to Add a FoodWastageRecord to the list of records in memory. IT SHOULD NOT add duplicate records. Return true if the record was added successfully, else return false. Delete a FoodWastageRecord from memory. Return true if the record was actually deleted. Return false if the record to be deleted wasn’t found. [NOTE: This is an extra credit requirement.] Get all FoodWastageRecord objects from memory Generate and return the FoodWastageReport All four of these will be the member functions of your class. food_wastage_tracker.hpp class FoodWastageTracker { public: bool AddRecord(const FoodWastageRecord &record); bool DeleteRecord(const FoodWastageRecord &record); const std::vector<FoodWastageRecord> &GetRecords() const; FoodWastageReport…
Which of the following statement(s) is(are) correct? Group of answer choices Both a. and b. Neither a. nor b. a. The default cut-off value in two-class classifiers is 0.5. b. The cut-off value can be adjusted to accept more records in high value class and to accept more misclassification errors where the misclassification error is low.
