Cloud services and its uses for good governance in Developing countries.

Suppose an algorithm A₁ has a runtime T₁(n) defined ( in seconds) by the following function

T₁(n) = n³ + 20n + 15

For n = 13, the runtime of the algorithm is 2472 seconds. Let us assume that we have an algorithm A₂ with runtime given by T₂(n) = n² + 22n + 14? What will be the lowest value of n for which the runtime of A₂ exceeds 2472 seconds?

Problem

(The Account class) Design a class named Account that contains:

■ A private int data field named id for the account.

■ A private float data field named balance for the account.

■ A private float data field named annualInterestRate that stores the current interest rate.

■ A constructor that creates an account with the specified id (default 0), initial balance (default 100), and annual interest rate (default 0).

■ The accessor and mutator methods for id, balance, and annualInterestRate.

■ A method named getMonthlyInterestRate() that returns the monthly interest rate.

■ A method named getMonthlyInterest() that returns the monthly interest.

■ A method named withdraw that withdraws a specified amount from the account.

■ A method named deposit that deposits a specified amount to the account.

Draw the UML diagram for the class, and then implement the class. (Hint: The method getMonthlyInterest() is to return the monthly interest amount, not the interest rate. Use this formula to calculate the monthly interest: balance * monthlyInterestRate. monthlyInterestRate is annualInterestRate / 12. Note that annualInterestRate is a percent (like 4.5%). You need to divide it by 100.)

Write a test program that creates an Account object with an account id of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the id, balance, monthly interest rate, and monthly interest.

Design and implement a class named Person and its two subclasses named Student and Employee.

Make Faculty and Staff subclasses of Employee.

A person has a name,address, phone number, and email address.

A student has a class status (year 1,year 2,year 3,or year 4).

An employee has an office, salary, and date hired.

Use the Date class from JavaAPI 8 to create an object for date hired.

A faculty member has office hours and a rank.

A staff member has a title.

Override the toString method in each class to display the class name and the person’s name.Design and implement all 5classes.
