- When a class can be derived from another class and use its methods, this is called Polymorphism. A. True B. FalseTrue or False, An abstract class must have at least one abstract method.In order to use the assignment operator on an instance of a class data type, it must be overloaded. Group of answer choices True False
- True/False: When instantiating an object of an abstract class, you can do it with the keyword new.Design a new Triangle class that extends the abstract GeometricObject class: Draw the UML diagram for the classes Triangle and GeometricObject 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 filled: The program should create a Triangle object with these 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 notSanchez Construction Loan Co. makes loans of up to $100,000 for construction projects. There are two categories of Loans—those to businesses and those to individual applicants. Write an application that tracks all new construction loans. The application also must calculate the total amount owed at the due date (original loan amount + loan fee). The application should include the following classes: Loan—A public abstract class that implements the LoanConstants interface. A Loan includes a loan number, customer last name, amount of loan, interest rate, and term. The constructor requires data for each of the fields except interest rate. Do not allow loan amounts greater than $100,000. Force any loan term that is not one of the three defined in the LoanConstants class to a short-term, 1-year loan. Create a toString() method that displays all the loan data. LoanConstants—A public interface class. LoanConstants includes constant values for short-term (1 year), medium-term (3 years), and…
