Question

I need to revise a previously written code with a class I just wrote. I don't know how to go about doing this. Can someone please help?


My Program:


     import java.util.Scanner;
     import java.util.Arrays;

    public class ModifiedLab7
    {
    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
       
        System.out.print("How many points? ");
        int n = input.nextInt();
       
        double[][] points = new double[n][2];
        for(int i = 0; i < n; i++)
        {
            System.out.print("Enter the (x, y) coordintes of point " + (i+1) + ": ");
            points[i][0] = input.nextDouble();
            points[i][1] = input.nextDouble();
        }

        double[][] distances = new double[n][n];
        for(int i = 0; i < n; i++)
            for(int j = 0; j < n; j++)
                distances[i][j] = distance(points[i], points[j]);
       
        double[] averages = new double[n];
        for(int i = 0; i < n; i++)
            averages[i] = average( distances[i] );
           
        int min = minimum_location( averages );
       
        System.out.printf("The smallest average is averages[%d] = %f ", min, averages[min]);
               
    }

    public static double distance( double[] p1, double[] p2)
    {
        return Math.sqrt( (p1[0]-p2[0])*(p1[0]-p2[0]) + (p1[1]-p2[1])*(p1[1]-p2[1]));
    }
   
    public static double average( double[] x )
    {
        double sum = 0;
        for(int i = 0; i < x.length; i++)
            sum += x[i];
           
        return (x.length > 0)? sum/x.length : 0.0;
    }
   
    public static int minimum_location( double[] x )
    {
        int min = 0;
        for(int i = 1; i < x.length; i++)
            if( x[i] < x[min] )
                min = i;
               
        return min;
    }
    }

My Class:

    class MyPoint
    {
    //Declare x and y variables
    private double X;
    private double Y;
   
    //Create MyPoint constructor at point (0,0)
    public MyPoint()
    {
    }
   
    //Create MyPoint constructor with specific coordinates
    public MyPoint(double X, double Y)
    {
        //Declare x and y variables with specific coordinates
        this.X = X;
        this.Y = Y;
    }
   
    //Create distance method from point to another of MyPoint type
    public double Distance(MyPoint SecondPoint)
    {
        return Distance(this, SecondPoint);
    }
   
    //Create distance method from point to another point with specific coordinates
    public static double Distance(MyPoint PointOne, MyPoint PointTwo)
    {
        return Math.sqrt((PointOne.X - PointTwo.X) * (PointOne.X - PointTwo.X) + (PointOne.Y - PointTwo.Y) * (PointOne.Y - PointTwo.Y));
    }
   
    //Create get x method
    public double GetX()
    {
        return X;
    }
   
    //Create get y method
    public double GetY()
    {
        return Y;
    }
    }

I tested my class already and I know it works. But just have no idea how to revise my program to use my MyPoint class
