Add the following method to the Point class: public double distance(Point other) Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, Y2) can be expressed as the square root of (x2 - x1P + (y2 - Y1}?. Two points with the same (x, y) coordinates should return a distance of e.e. public class Point { int x; int y; // // your code goes here

- Java - Encapsulation Create a class Point with attributes x and y which are both integers. Create getters and setters for these attributes and implement the following methods: 1. calculateDistance() - calculates the distance from the origin to the point. Returns a double, formula is sqrt(x^2 + y^2) 2. printCoordinates() - prints "(x,y)" Ask for user inputs for x and y. Use the methods printCoordinates() and calculateDistance() respectively. Inputs 1. X 2. Y Sample Output Enter x: 20 Enter y: 15 (20,15) 25.00import java.util.Arrays; public class Solver { // This constructor is called once to make a Solver object. // My tests will then use that one Solver object to solve many puzzles. // The most direct/intuitive solution leaves this constrctor blank. // However, adding some "preprocessing" code to this constructor // that executes before any puzzles are solved could potentially // speed up your solve method. public Solver() { } /** * Solves a given puzzle represented as a 5-by-5 boolean array with * 16 trues and 9 falses. * @param start the intial puzzle/board configuration * @return the sequence of moves that solves the puzzle. */ public char[] solve(boolean[][] puzzle) { //throw new RuntimeException("Not implemented"); } // A simple toy exmaple of how a Solver object is used. public static void main(String[] args) { boolean[][] bb = { { true, true, true, true, true}, {false, true, true, false, false}, { true, false, false, false, true}, { true, false, false, false, true}, { true, true,…1.
