Write a program to find if the given points form a parallelogram. Points are given in anti clock wise direction starting from bottom left point.

Input (Point, Point, Point, Point) Output (boolean)
`[4, 2], [6, 3], [6, 5], [4, 4]` true
`[0, 0], [5, 0], [8, 4], [3, 4]` true
`[-2, -2], [2, -2], [2, 0], [-2, 0]` true
`[5, 2], [9, 2], [9, 4], [7, 4]` false
`[2, 1], [8, 1], [9, 8], [6, 6]` false

``` class IsAParallelogram {     public static void main(String s[])    {        Point firstPoint = new Point(4, 2);        Point secondPoint = new Point(6, 3);        Point thirdPoint = new Point(6, 5);        Point fourthPoint = new Point(4, 4);        System.out.println("Is a parallelogram : " + isAParallelogram(firstPoint, secondPoint, thirdPoint, fourthPoint));    }     public static boolean isAParallelogram(Point firstpoint, Point secondPoint, Point thirdPoint, Point fourthPoint) { ```
