There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%.

- To construct an object of the type Book and initialise its properties, how would you go about using an object initializer? In?(?) = ?. ?? ?(?)1) Do you think it is possible to create another constructor with the same set of parameters? For example, adding the following constructor to Volunteer. Place a check (✓) beside your answer.Volunteer(): name_("Default"), branch_("CSU Long Beach") { } Yes, because you can overload constructors much like how you overload member functions. No, because the program will not know which constructor to use. No, because the body of the constructor is empty. 2) Much like constructors, member functions can also be overloaded. Write the name of Volunteer's overloaded member function. Take note that member function overloads need to have the same return type. 3) How do you think the compiler knows which member function overload it should call? Place a check (✓) beside your answer. It checks the name of the member function that was called. It compares the number of arguments and their data types with the member function's parameters. It always calls the overload with the least number of…
- answer question 3 in detail in regards through java and explain each step and reasons to the code(Implementing inheritance and apply the use of keyword super and this) Assume you have to develop a grading application for grading student's activity. Each activity will be given a numeric score (0 to 100), and accordingly will be given a grade (A, B. C. D. or F). The grade is given based on the condition in Table 1 below. Table 1: Scores and their corresponding grades Condition Letter Grade Score >= 90 A Score >= 80 В Score >= 70 Score >= 60 D Score < 60 F Create a class name GradedActivity, with an attribute to hold the score for the activity. The SetScore method sets the score from a given parameter value and the getScore method returns the score. A getGrade method should retum a grade's letter based on the given numeric score, according to the rules given in Table 1. Then create a new class Essay which extends the GradedActivity class. The new class is to detemine the grade a student receives for an essay based on the accumulated score (0 to 100), which is accumulated based on a…Use java and classes
- Language: C++ Use the previously given files: Critter.h, Critter.cpp and testcritter.cpp. Expand Critter.h by two additional properties of your choice, and corresponding setter and getter methods, then adjust Critter.cpp and testcritter.cpp accordingly. Also adapt the print () method such that the new properties are printed on the screen as well. You can assume that the input will be valid.Q1: There are different kinds of atoms with having neutrons , protons and electrons with their specific atomic masses. Hydrogen is one of them. In C# language, write a definition for an atom class that contains: Fields for storing the numbers of protons, neutrons and electrons with appropriate visibility. Setter and getter methods for manipulating these fields, ensuring that the minimum value for electrons and protons is 1, and the minimum value for neutrons is 0. A parameterized constructor that initializes new objects of atom to be the smallest element (Hydrogen), for which the number of protons is 1, the number of neutrons is 0, and the number of electrons is 1. Write a new method for the atom class called isIonthat will return true or false, depending upon whether the atom is an ion. An atom is an ion if it is charged (i.e., if the number of electrons ≠ the number of protons). Write a new method for the atom class called getAtomicMassNumberthat will calculate and return…To write an application that uses recursion to solve a problem. Details: Create a class called Power that computes the value of base exponent. The class should have one recursive method: • public static int power(int base, int exponent) – Which computes the value of base exponent using recursion, returning the result. The recursion step should use the following relationship base exponent = base x base exponent - 1 and the termination condition should occur when exponent is equal to 1, because base 1 = base NOTE: For the power method, assume the exponent parameter value is always greater than 0. Create a second class called PowerTest that contains the main method, and tests the Power.power method. The test class does not need to ask for input from the user of the class, nor does it need to do any additional error checking. Upload both source files to Blackboard. Note: Ensure that your program is properly formatted and it follows all Java naming conventions.
