So Shivam had just learned about OOP. He had written a program before that did two things,

• Find distance between two points
• Find direction (angle) between two points in Radians.

He has this code in the org.procedural.DistanceAndDirectionCalculator It looks like this for the reference -

public class DistanceAndDirectionCalculator {
    public static double distance(double x1, double y1, double x2, double y2) {
        double xDistance = x1 - x2;
        double yDistance = y1 - y2;
        return Math.sqrt(Math.pow(xDistance, 2) + Math.pow(yDistance, 2));
    }

    public static double direction(double x1, double y1, double x2, double y2) {
        double xDistance = x2 - x1;
        double yDistance = y2 - y1;
        return Math.atan2(yDistance, xDistance);
    }
}

He thought it'll be a good idea to convert this to Object Oriented Programming. So he wrote a new implementation in package org.oop, he got 2 classes -

• org.oop.DistanceAndDirectionCalculator
• org.oop.Point

However, his trainer told him that what he did is not Object Oriented programming and asked Shivam to try again.

• Try to articulate problems with Shivam's OOP solution. (Write it somewhere and share it with your trainer)
• Fork the project and fix the design related problem with Shivam's OOP solution. Share that with your trainer too.
