- JAVAAssignment:The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date createda. 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).
- Write a class named Employee that has the following fields: name: The name field is a String object that holds the employee's name. idNumber: The idNumber is an integer variable that holds the employee's ID number. department: The department field is a String object that holds the name of the department where the employee works. position: The position field is a String object that holds the employee's job title. Write mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three Employee objects to hold the following data. Name ID Number Azah Samsudin Mira Kamal Che Yah Sam Department Computer Science Biomedical Language Position Programmer Researcher Lecturer 11011 35125 80001 The program should store the data in the three objects and then display the data for each employee on the screen.Create a class called Account. Having private fields custname and protected field balance Define a constructor that takes custname and balance as inputs and sets appropriate fields. Create getname() and getbalance() methods. Create setname() for setting custname Create a method called add. This method takes one numerical input and adds it to balance. Create a method called subtract. This method takes one numerical input and subtracts it from balance Save this class to Account.java Write a Test class that creates objects of type Account. The Test class should create objects of Account type and call the object's methods. Subject: Java Programmingjava When we create an object of a class, the object's instance variables are automatically initialized with its default values without us writing code in any constructor. Choose one of the options:TrueFalse
- Review - Icecream Class • D • . Declare a class called Icecream Add a default constructor Add the following fields - flavor, scoopCount, isCone Add a method called setScoopCount that takes in a number for how many scoops and assigns it the scoopCount field. This method does not need to return anything. Add a method called setFlavor that takes the name of an ice cream flavor and assigns it the flavor field. This method does not need to return anything. Add a method called isCone that takes in a true or false value of whether or not the ice cream is on a cone or not. This method does not need to return anything. Add a method called getScoopCount that doesn't take in any values and returns the value of the scoopCount field • Add a method called getFlavor that doesn't take in any values and returns the value of the flavor field Add a method called isCone that doesn't take in any values and returns the value of the isCone field Add a method call addScoop that doesn't take in any values and…Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class(See the pic attached) The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin()should return the pin. check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance() should return the current balance. Finally, write a main() to demo your bank account class.
