Question
( Sort the points in a plane ) Write a program that meets the following requirements: Define a class named Point with two data fields
(Sort the points in a plane) Write a program that meets the following requirements:
- Define a class named Point with two data fields x and y to represent a point's x- and y-coordinates. Implement the Comparable interface for the comparing the points on x-coordinates. If two points have the same x-coordinates, compare their y-coordinates.
- Define a class named CompareY that implements Comparator
. Implement the compare method to compare two points on their y-coordinates. If two points have the same y-coordinates, compare their x-coordinates. - Randomly create 100 points and apply the Arrays.sort method to display the points in increasing order of their x-coordinates, and increasing order of their y-coordinates, respectively.
Here is the output for my one hundred random points:
