A Boolean value will be automatically returned to the Booking object which sends the message. O b. A value will be assigned to the attribute of the Booking object associated with message. O C. The attribute of the Membership object associated with message sent by the User object will be initialised. O d. The method of the Membership object associated with the message sent by the User object will be invoked.Create an Account Object project. 1. Create an Account class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The type of accounts are 1 (Savings) or 2 (Cheque) The constructor must assign the values of the parameters to the data fields/instance variables. The static field must be increased by one in the constructor. The setAccNumber() is a private void method. The account number must consist of the first 3 letters of the name of the account holder, the digit indicating the type of account and #-character and a 3-digit random value. This method must be called from the constructor. The makeDeposit() method must add the amount received as a parameter to the balance if the value received is not a negative value. The withdrawAmount() method must check whether the balance allows for the amount to be withdrawn. There must always be a minimum amount of R 100.00 in an account. If there is not enough money in the account to do the transaction,…Create an object-oriented program using decision making statements. The program should accept various user inputs. The program should also have the minimum structural requirements such as constructor, classes and objects. There should be a 2 classes.
