(private Date dateCreated)…arrow_forward(Account class)Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type int to represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display an error message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add an amount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged, and the function should print a message indicating "Debit amount exceeded account balance." Member function get_Balance should return the current balance. Create a program that creates two Account objects and tests the member functions of class…arrow_forward
- (The Time class) Design a class named Time. The class contains: - The data fields hour, minute, and second that represent a time. - A no-arg constructor that creates a Time object for the current time. (The values of the data fields will represent the current time.) -A constructor that constructs a Time object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. (The values of the data fields will represent this time.) -A constructor that constructs a Time object with the specified hour, minute, and second. - Three getter methods for the data fields hour, minute, and second, respectively. -A method named setTime (long elapseTime) that sets a new time for the object using the elapsed time. For example, if the elapsed time is 555550000 milliseconds, the hour is 10, the minute is 19, and the second is 10. Draw the UML diagram for the class and then implement the class. Write a test program that creates two Time objects (using new Time (), new Time(555550000),…arrow_forward(Geometry: MyRectangle2D class) Define the MyRectangle2D class that contains: Two double data fields named x and y that specify the center of the rectangle with getter and setter methods.

The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…arrow_forward

- (Rational Class) Create a class called Rational for performing arithmetic with fractions.Write a program to test your class. Use integer variables to represent the private data of the class—the numerator and the denominator. Provide a constructor that enables an object of this class to beinitialized when it’s declared. The constructor should contain default values in case no initializersare provided and should store the fraction in reduced form. For example, the fractionwould be stored in the object as 1 in the numerator and 2 in the denominator. Provide publicmember functions that perform each of the following tasks:a) Adding two Rational numbers. The result should be stored in reduced form.b) Subtracting two Rational numbers. The result should be stored in reduced form.c) Multiplying two Rational numbers. The result should be stored in reduced form.d) Dividing two Rational numbers.
