Consider the following class Point:

public class Point {

public float x;

public float y;

public float z;

public Point(int inX, int inY, int inZ)

{

x = inX;

y = inY;

z = inZ;

}

}

In the client code, ArrayList is created, and 3 points are added to it:

import java.util.ArrayList;

import java.util.Collections;

public class Lab6Main {

public static void main(String[] args) {

ArrayList Points = new ArrayList();

Points.add(new Point(1, 2, 3));

Points.add(new Point(0, 0, 0));

Points.add(new Point(0, 34, 68));

//Collections.sort(Points);

}

}

1. Create 2 files Point.java and Lab6Main.java for Point class and client code; copy the code. Compile and run the project.

2. Uncomment the last line in main() method (Collections.sort(Points);) Try compiling and running the code again and analyze the error. Update the Point class so that sorting works properly. Note: you need to implement Comparable interface. Points should be sorted according to the following logic:

• Compare x coordinates:
  • If they are different, return the difference;
  • If they are equal, compare y coordinates:
    • If they are different, return the difference;
    • If they are equal, compare z coordinates:
      • If they are different, return the difference;
      • If they are equal, objects should be equal (so you can use one difference operation to compare z)

I do not understand how to compare the coordinates. i've been trying t figure this out for an hour. I'm stuck
