Write a program to get the smallest angle of a triangle formed by the given points. Round the resultant angles to the nearest integer value.

Input (Point, Point, Point) Output (double)
[0, 0], [5, 0], [0, 5] 45.0
[90, 0], [0, 0], [45, 77.94] 60.0
[0, 2], [5, 0], [0, 5] 23.0
[0, 0], [10, 0], [5, 7.666] 57.0
[25, 43], [50, 0], [50, 43] 30.0

class CalculateTheSmallestAngle

{    public static void main(String s[])
    {
        Point firstPoint = new Point(0, 0);
        Point secondPoint = new Point(5, 0);
        Point thirdPoint = new Point(0, 5);
        System.out.println("The smallest angle of the triangle is : " + getSmallestAngle(firstPoint, secondPoint, thirdPoint));

    }


public static double getSmallestAngle(Point firstPoint, Point secondPoint, Point thirdPoint) {
//Write code here to get the smallest angle of a triangle.
}

//If required write any additional methods here
}
class Point {

double x;
double y;

Point(double x, double y) {
this.x = x;
this.y = y;
}
}
