If we know the length of three sides of a triangle, we can calculate the area of a triangle using Heron's Formula: Area of a Triangle = (s* (s-a)* (s-b)* (s-c)) Where s = (a + b + c)/2 (Here s = semi perimeter and a, b, c are the three sides of a triangle) public class Student { private List<Course .
