- 6. Design a Java class with a main method that does the following. You must include a meaningful comment for main and each method a. Main invokes a method readScores to read input from a file (name of your choice) that contains the name of the bowlers (no more than 25) and their bowling scores (two scores per bowler). The program stops reading values when it has reached the end of the file. For example, the file might contain: Bob 203 176 Jane 210 253 Jack 300 189 Eileen 220 298 • As the method reads the data, it stores the name into a String array and the average of the two bowling scores into an array of double. • The method returns the actual number of bowlers read in b. Main then invokes a method computeOverallAvg to: compute (a) the overall average score of all the bowlers combined, (b) the average score and name of the bowler with the highest average score and (c) the average score and name of the bowler with the lowest average scores. print to the console (a) the overall average…Important note: your code must compile correctly and run without errors. Otherwise, your code will get the grade zero. Question 1: Implement a java class called ParsingCustomerRecords that has the following data members and functions: ParsingCustomerRecods - customerRecords: array of strings - result: string variable - recordsNumber: int variable -fileName: string variable + Constructor(String filename, int recordsNumber) + void Reader() + void Executor() + void showResult() + String toString() All of the data members are private, and all of the methods are public. Constructor has two parameters which are (1) the file name in which Customers’ records are stored, and (2) the number of the records in the file. The constructor functionality is to assign suitable initial values to the fileName and recordsNumber data members. The constructor also should instantiate the customerRecords array, where the size of the array should be equal to recordsNumber. Reader…{In Java Programming Please} Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson. In the main method, create objects of each class…
- 1. Write Java code to do the following with one or more Primitive Wrapper Classes: A. Declare a variable and initialize it to a responsible value B. Use a field of that class C. Use a static method of that class D. Use an instance method of that variableKindly Solve this C++ question as per the instructions. Thank you for your help! Instructions: 1- Put the class definition in Flight.h and the implementation of the constructors and functions in Flight.cpp Implement the Flight.h and Flight.cpp so that class Flight contains: 4 private instance variables: Name of data type string, which describe the three electric vehicle charger types (AC975, DL521, and AC863). Destination of data type string that shows the final destination of that flight. Hour and Minute of data type int that show the departure time. A default constructor which sets all of the numeric instance variables to zero and the String instance variables to null. A constructor with 4 parameters that sets the 4 instance variables to the corresponding values passed. Implement an accessor method for each information (Flight name, Flight destination, and Flight Time) that will return the value of the instance variable. For example, the getX() method for the instance variables…7. Write a program in java to declare and define a class using the below mentioned details. a.

Make sure the rules below are followed for the code. For coursework students:(a) There are two assignments, each marked out of a maximum of 100 marks and equally weighted.The marks for each assignment are recorded separately.(b) There is weekly practical work. The marks for this component are recorded as a total markobtained (marked out of a maximum of 20 marks) for all practical work demonstrated during thesemester.(c) There is one final examination that is marked out of a maximum of 100 marks and recordedseparately.(d) An overall mark (to be calculated within the class)(e) A final grade, which is a string (think of a way to avoid code duplication for calculating this)The final grade, for coursework students, is to be awarded on the basis of an overall mark, which is anumber in the range 0 to 100 and is…I need help in coding these two classes(dorm and room) in JAVA from the following information-> *A dormitory has a name and has several rooms. When a dormitory is built, the name and the number of rooms should be provided. In some cases, the maximum capacity of the rooms is also provided. If there is no maximum capacity set, each room can accommodate at most 6 guests. *The rooms are then automatically created and added to the dormitory, numbered from 1, 2, 3, and so on, representing the room number. Once the room number is assigned to the created room, this information cannot be edited anymore. *The dormitory can accept guests into a given room number. Each guest has a name and nationality. If the capacity is full or an invalid room number is provided, the guest will not be added and this method returns false. Otherwise, this method returns true. *The dormitory also has a method to return the guests in a given room number. If an invalid room number is provided, the method will…
