My parray variable is already a Point type array; can you tell me why it is giving me an error? I tried a couple different conversions and java didn't like them.
Thank you!

import java.util.*;


public class FinalExam {

    
    public static void main(String[] args) {
        FinalExam fe = new FinalExam();
        Point[] parray = new Point[8];// there are only 8 Points
        fe.inputPoints(parray);
        System.out.println("All the Points in this plain");
        for (Point p : parray) {
            System.out.println(p);
        }
        Point[] pair = fe.shortestDistance(parray);
        System.out.println("Points with shortest distance between them");
        System.out.println(pair[0] + " and " + pair[1]);
        System.out.println("Point Closest to zero is : "
                + fe.closestToZero(parray));
    }

    
    public void inputPoints(Point[] parray) {
        Scanner input = new Scanner(System.in);
        System.out.println("Enter 8 points " + "\n");
        int points = input.nextInt();
        parray = new Point[points];

You're trying to treat a one-dimensional array as a two-dimensional one. You can't

btw please use code tags as you were asked. If you need to highlight lines, do it with obvious comments
