BankCharges Class
A bank charges $10 per month, plus the following check fees for a commercial checking account:
$.10 for each check if less than 20 checks were written
$.08 for each check if 20 through 39 checks were written
$.06 for each check if 40 through 59 checks were written
$.04 for each check if 60 or more checks were written
The bank also charges an extra $15 if the account balance falls below $400 (before any check fees are applied). Design a class that stores the ending balance of an account and the number of checks written. It should also have a method that returns the bank’s service fees for the month.

- Invoicing.java Create a class named Invoicing (no instance private data fields) that includes three overloaded computeInvoice() methods and one displayDetails() method for a book store: see pages 140 and 183 for examples... * Define a constant for the 8% tax rate at the top of the Invoicing class. Set the TAXRATE double constant to 0.08. Do not set to a whole number. When computeInvoice() receives a single parameter, it represents the price of one book ordered. Calculate the tax using the TAXRATE constant. Add the tax to the price and save the total due in a variable. Call the displayDetails() method, defined in the computeInvoice() class, being sure to pass the total due as an argument to the display method. * When computeInvoice() receives two parameters, they represent the price of a book and the quantity ordered. Multiply the price times quantity, calculate the tax using the TAXRATE constant, and calculate the total due. Call the displayDetails() method, defined in the…arrow_forward(Physics: acceleration) Average acceleration is defined as the change of velocity divided by the time taken to make the change, as shown in the following formula: a = (v1 - v0) / t Here, v0 is the starting velocity in meters per second, v1 is the ending velocity in meters per second, and t is the time span in seconds. Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration.

It has the following members: a) -int startTime; // variable tracking when the timer was started (unused when timer is not running). In number of seconds since 1970 b) -int timeOnClock; // variable tracking the time on the clock since last reset in seconds c) -bool isRunning; //variable tracking wether the clock is running or stopped d) +Timer(); //constructor, initializes all to zero/false e) +Timer(bool startNow); // constructur that starts clock automatically if startNow is true f) +int getTime(); // returns time on clock in seconds. If clock is running, this must also include the time since it was last started g) +void addTimeToClock(int seconds); // allows manually adding time to the clock h) +void reset(); // resets time on clock to zero i) +void start(); // starts clock j) +void stop(); // stops clock k)…arrow_forward
- A(n) ____________ is one instance or variable of a class.arrow_forwardQuadratic equations The form of a quadratic equation is ax2 + bx + c = 0. Write a program that solves a quadratic equation in all cases, including when both roots are complex numbers. Remember that the solutions are x = (-b + sqrt(b2 -4ac))/2a and (-b - sqrt(b2 -4ac))/2a For this you will need to set up the following classes: Complex: Encapsulates a complex number. ComplexPair: Encapsulates a pair of complex numbers. Quadratic: Encapsulates a quadratic equation. – Assume the coefficients are all of type int for this example. SolveEquation: Contains the main method. (I give this to you it is shown below) Along with the usual constructors, accessors and mutators you will need the following additional methods: In the Complex class a method called isReal to determine whether a complex object is real or not returning a boolean value. In the ComplexPair class a method bothIdentical that determines if both complex numbers are identical, returning a boolean value. In the…arrow_forward# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…arrow_forward
- JAVA PROGRAMMING Write two java files for this assignment: Circle.java, and Main.java. The Circle.java file will create an actual class. The Circle class: MEMBER VARIABLE double radius double x double y Eight methods: Six of the methods are simple: getter’s and setter’s for x, y, and radius. There should also be a getArea method that returns the area (derived from the radius) A doesOverlap method. This method should accept a Circle as an argument, and return true if this circle overlaps the circle that the method was invoked on. [Note: two circles overlap if the sum of their radius' is greater than or equal to the distance between their centers.] void setX(double value) double getX() void setY(double value) double getY() void setRadius(double value) double getRadius() double getArea() boolean doesOverlap(Circle otherCircle) second class will be the typical replit Main class, with its static main method .It should contain code that tests the Circle class. submit code that…arrow_forwardpython3: Class vs Instance variable Make a class names Foo Add a class variable to foo called x and initialize it to 5 Add an instance variable to foo called y and initialize it to 100 Make an instance of the class, call it f Using Foo., print out the value of x (proper etiquette for class variables) Using f., Print out the value of y (proper etiquette for instance/self. variables) Hint: remember that class variables are the ones where their value is the same for all instances/clones. And instance variable (which you declare inside the __init__ method with the self. preface, are unique to each clone. When you print a class variable the proper way is to use classname . (for example Foo.x) and when you print an instance variable you use the instance handle (for example f.y.)arrow_forwardArea of a rectangle = length * width Create a Class that calculates and prints out the area of a rectangle.

Accepts the radius of the circles as an argument. Constructor. A no-arg constructor that sets the radius field to 0.0. setRadius. A mutator method for the radius field. getRadius.An accessor method for the radius field. area. Returns the area of the circle, which is calculated as area. Returns the area of the circles, which is calculated as area= PI * radius * radius diameter. Returns the diameter of the cirlce, which is calculated as diameter = radius * 2 circumference. Returns the circumference of the circle, which is calculated as circumference = 2 * PI * radius Write a program that demonstrates the Circle class by asking the user for the circles's radius, creating a Circle object, and then reporting the cirlce's area, diameter, and circumference.arrow_forward10.15 LAB: Car value (classes) Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 Note: print_info() should use three spaces for indentation. python class Car: def __init__(self): self.model_year = 0 # TODO: Declare purchase_price attribute self.current_value = 0 def calc_current_value(self, current_year): depreciation_rate = 0.15 # Car depreciation formula car_age = current_year - self.model_year self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age) # TODO: Define print_info() method to output model_year, purchase_price, and current_value if __name__ ==…arrow_forwardWRITE PLEASEJAVA write grading program for a class with the following grading policies. thers a total of 2 quizzes, each graded on the basis of 10 points. theeres is 1 midterm exam and one final exam, each graded on the basis of 100 points. final exam counts for 50% of the grade, the midterm counts for 25%, and the 2 quizzes together count for a total of 25%.
