Get the area of a triangle - Java Quiz Question

Write a program to get the area of a triangle.

Input (Point, Point, Point)	Output (double)
`[0, 0], [5, 0], [5, 5]`	12.5
`[-7, 0], [3, 0], [3, 10]`	50.0
`[2, 2], [6, 2], [6, 6]`	8.0
`[3, 1], [1.5, 1.2], [2.5, 4.3]`	2.425
`[-2, 0], [1, 0], [0, -3]`	4.5


			

			class AreaOfATriangle 
 { 

			    public static void main(String s[])
    {
        Point firstPoint = new Point(0, 0);
        Point secondPoint = new Point(5, 0);
        Point thirdPoint = new Point(5, 5);
        System.out.println("Area of a triangle : " + areaOfATriangle(firstPoint, secondPoint, thirdPoint));

    }
 
			

			

					    public static double areaOfATriangle(Point firstPoint, Point secondPoint, Point thirdPoint) {


			
}
			

					class Point { 

					 

					double x; 

					double y; 

					 

					Point(double x, double y) { 

					this.x = x; 

					this.y = y; 

					} 

					}
