In this exercise, you have to create a class called Point which can calculate distance between two points in the x-y plane. Problem Statement# You have to implement a class called Point that represents a specific point in the x-y plane. It should contain the following: ● fields: ○ x( integer type) ○ y( integer type) ● methods: ○ default constructor that initializes the point at (0,0)(0, 0)(0,0) ○ parameterized constructor that takes input x and y and initializes the point to the respective coordinates. ○ float distance(), a method which calculates the distance of the point (represented by the object) from the origin, i.e. (0,0)(0, 0)(0,0) ○ float distance(x1, y1), a method which calculates the distance between the point represented by the class object and (x1,y1)(x1, y1)(x1,y1) Sample Input# Point p1 = new Point(5, 5); Sample Output# distance() => 7.071 distance(2, 1) => 5.0 Part of the solution import java.lang.Math; class Point { // Private fields private int x; private int y; // Default Constructor public Point() { // Implement the function } // Parameterized Constructor public Point(int x, int y) { // Implement the function } public double distance() { // Implement the function return 0; } public double distance(int x2, int y2) { // Implement the function return 0; } } class Demo { public static void main(String args[]) { Point p1 = new Point(5, 5); System.out.println(p1.distance()); System.out.println(p1.distance(2, 1)); } }
