Create a class named Billing that includes three overloaded computeBill() methods for a photo book store. •• When computeBill() receives a single parameter, it represents the price of one photo book ordered. Add 8% tax, and return the total due. •• When computeBill() receives two parameters, they represent the price of a photo book and the quantity ordered. Multiply the two values, add 8% tax, and return the total due. •• When computeBill() receives three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and return the total due. Write a main() method that tests all three overloaded methods. Save the application as Billing.java.

Build a class called BankAccount that manages checking and savings accounts. The class has three private member fields: a customer name (String), the customer's savings account balance (double), and the customer's checking account balance (double). Implement the following Constructor and instance methods: public BankAccount(String newName, double amt1, double amt2) - set the customer name to parameter newName, set the checking account balance to parameter amt1 and set the savings account balance to parameter amt2. (amt stands for amount)public void setName(String newName) - set the customer namepublic String getName() - return the customer namepublic void setChecking(double amt) - set the checking account balance to parameter amtpublic double getChecking() - return the checking account balancepublic void setSavings(double amt) - set the savings account balance to parameter amtpublic double getSavings() - return the savings account balancepublic void depositChecking(double amt) - add…
Create a class named Pay that includes five double variables that hold hours worked, rate of pay per hour, withholding rate, gross pay, and net pay. Create three overloaded computeNetPay() methods. When computeNetPay() receives values for hours, pay rate, and withholding rate, it computes the gross pay and reduces it by the appropriate withholding amount to produce the net pay. (Gross pay is computed as hours worked multiplied by pay per hour.) When computeNetPay() receives two parameters, they represent the hours and pay rate, and the withholding rate is assumed to be 15%. When computeNetPay() receives one parameter, it represents the number of hours worked, the withholding rate is assumed to be 15%, and the hourly rate is assumed to be 5.85. Write a main() method that tests all three overloaded methods. Save the application as Pay.java.
1: create a class Pentagon, which implements the RegularPolygon interface. It should have a double field called length, as well as a constructor that initializes this length field to a given value. 2: In the main() method of Pentagon class, add the following code: RegularPolygon sq = new Square(10); RegularPolygon penta = new Pentagon(20); Write code to get the perimeter for sq and penta. 3: In the main() method defined in Q2, add this line of code: sq.getArea(); Will this code pass through compiler? What is the reason? The Java feature in Q1 which create a new version of predefined method getPerimeter() is called Polymorphism Override Overload Inheritance

Create a class with the name 'QuadraticSolver'.The two roots of a quadratic equation of the form ??2 + ?? + ? = 0 can be obtained using the quadratic equation formula ?2 − 4?? is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots. In the QuadraticSolver main method, write a program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display one root. Otherwise, display the imaginary roots. Note that you can use Math.pow(x, 0.5) to compute √?. Here are three separate sample runs: 1.0, 3, 1The equation has two roots: -0.38 and -2.62 1, 2.0, 1The equation has one root: -1.00 1, -4, 8The equation has two imaginary roots: 2.00 + 2.00i and 2.00 - 2.00i

I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
Java ProgramFollowing the example of the Circle class in Section 9.2, design a class named Rectangle to represent a rectangle. The class contains:- Two double data fields named width and height that specify the width and height of the rectangle. Thedefault values are 1 for both width and height.- A no-arg constructor that creates a default rectangle.- A constructor that creates a rectangle with the specified width and height.- A method named getArea() that returns the area of this rectangle.- A method named getPerimeter() that returns the perimeter Draw the UML diagram for the class then implement the class. Write a test program that creates two Rectangle objects—one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.
PLEASE FAST Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() and the equals() methods. The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation of the country inserted last. Display countries whose area is greater than 10000 km2.
