Write a program that creates a class named BankAccount and contains: • Private attributes: o id (an int), balance (a double), and annualInterestRate (a double). o count (a static int) to keep a record of the number of created objects. Constructors: o A 2-argument constructor that creates an account with given annualInterestRate and balance, increments count by 1, and then stores the new count into id o A no-argument constructor that invokes the 2-arg constructor and sets both balance and annualInterestRate to 0. Methods: o Getter methods for balance, annualInterestRate, and id. o Setter methods for balance and annualInterestRate. o getMonthlyInterest (): returns the monthly interest (not the interest rate). Monthly interest is balance * annualInterestRate / 12. Note that the interest rate is a percentage, e.g. 4.5%. You need to divide it by 100. o withdraw (): withdraws a specified amount from the account. o deposit (): deposits a specified amount to the account. o displayInfo (): displays the information of a bank account as shown in the sample run below.

- In this java assignment, we will be creating a paystub for an employee using classes, files, getters, and setters. Each file should only have one class and the class should share the same name as the file. We are going to implement the following classes: Employee - This class represent the employee. It needs the following fields exposed via getters and setters: Employee ID (hard code it to 1) First name, last name, middle initial Address, city, zip Phone, email Hourly rate PayPeriod - This class represents an employee's payment information. An employee will eventually have more than one pay period. It needs the following fields exposed via getters and setters: Pay period Id (hard code to 123456) Employee Id Start date, end date Number of hours PayrollManager - This class provides the functionality we need to compute and display the payroll. It should implement the following methods: double CalculateGrossPay (Employee, PayPeriod) - this should return the total gross for the…Build a class called BankAccount that manages checking and savings accounts.

Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7).

- a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).Consider this scenario, a mehtod in some class needs to access a data field in another class, here are two possible implementations: public class Process { /* * Check if student qualifies for financial help */ void check(Student student) { //.... } /* * Check if student qualifies for financial help */ void check(double studentGPA) { //.... }} In class Process, which check method you think is better, why? In other words, should we pass the object to the method or just the data member it needs? Disucuss the Pros and Cons of each approach (if any). Assume class Student has a mehod called getGPA( ).This question concerns writing a Student class to model a student's name, composed of a first name, middle name and last name. The Student class should meet the following specification:Class StudentA Student object represents a student. A student has a first name, middle name and last name.Methodspublic void setNames(String first, String middle, String last)// Set the first, middle and last names of this Student object.public String getFullName()// Obtain the full name of this Student with the middle name converted to an initial only.2Thinking of the problem in terms of testing, there are three requirements that must be met:1. The setNames() method sets the names stored in the object i.e. the values of firstName, middleName, lastName.2. The getFullName() method obtains the name of the student with the middle name converted to an initial only.3. The getFullName() method does not change anything – i.e. it does not modify the values of firstName, middleName, lastNameHINT: To start your…
