Question

Calculates the distance between two points of N dimensional space.

If the two points are in different dimensions, print the distance as -1.

Use Euclid Distance and Manhattan Distance.

Thanks!

**Use the code below and complete the rest.**

public class Distance2 {
public static void main(String[] args) {
Point p1 = new Point(new double[] {1.0, 2.0, 3.0});
Point p2 = new Point(new double[] {4.0, 5.0, 6.0});
System.out.println("Euclidean Distance: " + EuclidDistance.getDist(p1, p2));
System.out.println("Manhattan Distance: " + ManhattanDistance.getDist(p1, p2));
Point p3 = new Point(new double[] {1.0, 2.0, 3.0});
Point p4 = new Point(new double[] {4.0, 5.0});
System.out.println("Euclidean Distance: " + EuclidDistance.getDist(p3, p4));
System.out.println("Manhattan Distance: " + ManhattanDistance.getDist(p3, p4));
}
}

Create a new class Point.java and copy the following code

class Point
{
    private double []coords;

    Point ( double[] coords)
    {
        this.coords = coords;
    }

    double[] getCoords()
    {
        return this.coords;
    }
}

Create a new class EuclidDistance.java and copy the following code

class EuclidDistance
{
   static double getDist(Point pt1, Point pt2)
   {
     if( pt1.getCoords().length == pt2.getCoords().length)
     {
       double sum =0;
       for (int i= 0 ;i< pt1.getCoords().length;i++)
         sum = sum + Math.pow((pt2.getCoords()[i] - pt1.getCoords()[i]), 2);
            return Math.pow(sum,0.5);
     }
     else
       return -1;
   }
}

Create a new class ManhattanDistance.java and copy the following code

class ManhattanDistance
{
    static double getDist(Point pt1, Point pt2)
    {
        if( pt1.getCoords().length == pt2.getCoords().length)
        {
            double sum =0;
            for (int i= 0 ;i< pt1.getCoords().length;i++)
              sum = sum + Math.abs(pt2.getCoords()[i] - pt1.getCoords()[i]);
            return sum;
        }
        else
            return -1;
    }
}
