[In c#]
Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operator
(Java)
Open up Eclipse and create a new class called ArrayListPractice.java
Next, copy and paste the below program into your file and run the code.
Your job is to take the given code, remove all the arrays and replace them with the identical ArrayLists. There should be no arrays in your program.
You will need to call the ArrayList methods as defined in the lesson notes above.
Note that you will not be able to do method overloading with ArrayLists so you should assign different names to your methods.
Once you have made the changes, you should get identical output as the given version of the program.
Submit your program when you are finished.

This class stores only the Cartesian coordinates of the four corners of therectangle. The constructor calls a set function that accepts four sets of coordinates and verifies thateach of these is in the first quadrant with no single x- or y-coordinate larger than 20.0. The set function also verifies that the supplied coordinates do, in fact, specify a rectangle. Provide member functions that calculate the length, width, perimeter and area. The length is the larger of the twodimensions. Include a predicate function square that determines whether the rectangle is a squarearrow_forward
- (Coding Language C++) Dynamic Programs Hoskins College offers both curriculum and continuing education courses. Write a program that dynamically tracks these courses using an array of object pointers. Every course (both curriculum and continuing education) has a course id, title, room number, and number of contact hours. A curriculum course has credit hours and tuition rate. Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object. Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes. Part B: Modify your program. Remove the objects you created in main to test the classes.

The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again.
