solve using Java.

Q1. Write the code for the following UML diagram using Inheritance Fu (The Triang7e class) Design a class named Triangle that extends GeometricObject. The class contains: Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of a triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specified side1, side2, and side3. The accessor methods for all three data fields. A method named getArea () that returns the area of this triangle. A method named getPerimeter () that returns the perimeter of this triangle. A method named toString () that returns a string description for the triangle. For the formula to compute the area of a triangle, see Programming Exercise 2.19. The toString () method is implemented as follows: return "Triangle: side1 ="+ side 1+ "side2 ="+ side 2+ " side 3= " + side 3 ; Draw the UML diagrams for the classes Triang 1e and Geometric0bject and implement the classes. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and fi11ed properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not. (The Account class) Design a class named Account that contains: A private int data field named id for the account (default 0 ). A private double data field named ba 1ance for the account (default 0 ). A private double data field named annua1 InterestRate that stores the current interest rate (default 0). Assume that all accounts have the same interest rate. - A private Date data field named datecreated that stores the date when the account was created. A no-arg constructor that creates a default account. - A constructor that creates an account with the specified id and initial balance. - The accessor and mutator methods for id, bal ance, and annua1 InterestRate. - The accessor method for dateCreated. - A method named getMonthlyInterestRate () that returns the monthly interest rate. A method named getMonth1yInterest () that returns the monthly interest. A method named withdraw that withdraws a specified amount from the account. - A method named deposit that deposits a specified amount to the account. Draw the UML diagram for the class then implement the class. (Hint: The method getMonth1yInterest () is to return monthly interest, not the interest rate. Monthly interest is ba1ance * month1yInterestRate. month1yInteres tRate is annua1 InterestRate / 12. Note annualinterestRate is a percentage, for example 4.5%. You need to divide it by 100 .) Write a test program that creates an Account object with an account ID of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the wi thdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the balance, the monthly interest, and the date when this account was created. Q4. Please note that Exercise 9.7 in this Question refers to the Q3 of this assignment. The get and set methods for these data fields are provided in the class, but omitted in the UML diagram for brevity. The date of this transaction. The type of the transaction, such as "W" for withdrawal, "D" for deposit. The amount of the transaction. The new balance after this transaction. The description of this transaction. 11.6 The Transaction class describes a transaction for a bank account. - Modify the withdraw and deposit methods to add a transaction to the transactions array list. - All other properties and methods are the same as in Programming Exercise 9.7
