OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your…

First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information: A. Title of the student (eg Mr, Miss, Ms, Mrs etc)B. A first name (given name)C. A last name (family name/surname)D. Student number (ID) – an integer number (of type long)E. A date of birth (in day/month/year format – three ints) - (Do NOT use the Date class from JAVA)The student class will have at least the following constructors and methods:(i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables.(ii) a reasonable number of set and get methods.(iii) methods to compute the final overall mark and the final grade (which will be overridden in the respective child classes). These two methods will be void methods that set the appropriate instance variables. Remember one method can call another method. If you prefer, you can define a single method that sets…
