GeometricTriangle class

Design a class named GeometricTriangle that inherits from GeometricObject (what we did in class).

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 default constructor that creates a default triangle

· A constructor that creates a triangle with specified three sides.

· The accessor and mutator methods.

· A method named getArea() that returns the area of the triangle.

o Before the area is calculated check for valid input. Sum of any two sides should be greater than the third one. If not throw an IllegalArgumentException.

· A method named getPerimeter() that returns the perimeter of the triangle.

· A method named toString() that returns the string description for the triangle like for the circle and rectangle.

For a triangle with sides a,b and c area is calculated using semiperimeter s as shown below:

You can write a main to test the class the functions and the exception.
