/** Abstract method getArea */
public abstract double getArea();
/** Abstract method getPerimeter */
public abstract double getPerimeter();
}
The Triangle class contains:
- Three double data fields named side1, side2, and side3
- A default constructor that creates a triangle with three sides of length 1.0
- A constructor that creates a triangle with specified values for side1, side2, and side3
- Accessor methods for all three data fields
- A method called getArea() that returns the area of a triangle
- A method named getPerimeter() that returns the perimeter of the triangle
Test your Triangle class in a Drive program (in the same file) that prompts the user to enter the three sides of the triangle, the color, and whether or not the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties. Then, it should display the area, perimeter, color, and filledvalue .
