- Write a code for a banking program.a) In this question, first, you need to create a Customer class, this class should have:• 2 private attributes: name (String) and balance (double)• Parametrized constructor to initialize the attributes• Methods:i. public String toString() that gives back the name and balanceii. public void addPercentage; this method will take a percentage value andadd it to the balanceb) Second, you will create a driver class and ask the user to enter 6 customers’ informationand then you will create an array of Customer objects.c) Then you use this array used for various operations as shown in the output.• Using the array of customer objects, you need to search for all customers whohave less than $150• Using the array of customer objects, you need to get the average balance of thebalances in this array• Using the array of customer objects, you need to get the customer with thehighest balance and lowest balance• Using the array of customer objects, you need to show all…Create a class BeautyProduct with name, color, brand. Provide Constructors, getters, setters and also write toString method. Now create a class Lipstick which extends the class BeautyProduct as Lipstick is-a Beauty Product it has totalVolume, remainingVolume, price, texture (gloss, matt) as private data members. Provide Constructors, getters, setters and an apply() method whenever this method is called a beauty item is applied and its volume decreases by 10.This should also check that volume must not be zero if it then u have to throw exception. Also write toString method which prints all details like name, color, brand, price, texture and volume. Create another class foundation having totalVolume, remainingVolume, price, texture (liquid, cake) and lastingTime (number of hours foundation remain intact on face and does not crease) as private data members. This also extends the base class i.e. BeautyProduct. Provide Constructors, getters, setters and an apply() method whenever this…Exercise 4: Create class Author with following instance variable and methods. Instance variables: name (String), email (String), and gender (char of either 'm' or 'f); Constructor: Author (String name, String email, char gender) Methods: getName(0), getEmail(), setEmail(), getGender(), toString(). Then create class called Book is designed to model a book written by one author. It contains: Four private instance variables: name (String), author (of the class Author you have just created, assume that a book has one and only one author), price (double), and qty(int); Two constructors: Public Book(String name, Author author, double price) Public Book(String name, Author author, double price, int qty) public methods getName(), getAuthor(), getPrice(), setPrice(), getQty), setQty(), toString() Write the Book class (which uses the Author class written earlier). Also write a test driver called TestBook to test all the public methods in the class Book. Take Note that you have to construct an…
- java programming Robot Class : a robot has a name , located at a point with integer coordinates , faces north , east , south , or west and keeps a record of all its movements positions . The class has the following methods : A default constructor that initializes robot's name to " Unknown ” , location to ( 0,0 ) , direction to North , and travelled distance to 0 , and simulated movements to null . A constructor that given robot's name , starting location , and facing direction , Accessor methods to access all the instance variables and the simulated movements of the robot Mutator methods that change the instance variables to given values and they made the change for only suitable values . tumLeft and turn Right methods that change the direction of the robot but not the location move method that moves the robot by one unit in the direction it is facing . get Travelled Distance method that retums how many units has the robot moved .Define the Student class that has two attributes: name and gpa Implement the following instance methods: A constructor that sets name to "Defualt name"(What ever you want to give) and gpa to 1.0 set_name(self, name) - set student's name to parameter name get_name(self) - return student's name set_gpa(self, gpa) - set student's gpa to parameter gpa get_gpa(self) - return student's gpa Ex. If a new Student object is created, the default output is: Default name/1.0 Ex. If the student's name is set to "Frank" and the gpa is set to 3.7, the output becomes: Frank/3.7•Person Class: Person class has attributes: String name, address and int age.

The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method calledJava Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.
