(Triangle class) Design a new Triangle class that extends the abstract Geometricobject class. Draw the UML diagram for the classes Triangle and Geometricobject then implement the Triangle class. 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 filed. The program should create a Tri- angle object with the se sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
(CLO3) Read the following description and answer the following questions about it: Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be flexible enough to be able to add more options in the future, if needed. CustomerOrder -carColor: String -carModel: String -hasAirCondition: boolean Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder. Q2) Write a Java main() method to create an object of class CustomerOrder with color "red" and without air condition.
(Triangle class) Design a new Triangle class that extends the abstract GeometricObject class. Draw the UML diagram for the classes Triangle and GeometricObject and then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a colour, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the colour and filled properties using the input. The program should display the area, perimeter, colour, and true or false to indicate whether it is filled or not.
