- # Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…1. void start() { } A a = new A(); B b = new B(); a.s(b); b = null; /* Line 5 */ a null; /* Line 6 */ System.out.println("start completed"); /* Line 7 */ When is the B object, created in line 3, eligible for garbage collection? after line 5 B after line 6 Cafter line 7 There is no way to be absolutely certain.JAVA: The Plant class has one instance variable called name. Tree inherits from Plant and adds a height instance variable. Flower also inherits from Plant and adds a color variable. All classes have the usual constructors, accessors, mutators and toString. a) Write a Java program segment (not an entire program) that creates one array containing 2 different trees and 2 different flowers created using parameterized constructors. Include a loop that will write out the details of each object in the array. b) Can the tree object in the array call its setHeight method? Give reasons for your answer. If your answer is no, is there some way for this object to call its setHeight method?
- Assignment: Enhancing Dice Roll Stats Calculator Program Introduction: The project involves creating a program to roll pairs of dice, gathering statistics on the outcomes. Probability differs in the roll of two dice compared to a single die due to varied combinations. Dice Roll Series: User greeted with "Welcome to the Dice Roll Stats Calculator!" and prompted to specify rolls. Java classes: DiceRoller, Indicator, Validator. DiceRoller: Arrays: rollSeries (captures results), statIndicators (stores statistical indicators). Constructor rolls dice as per user request. Methods collect stats and print the report. Indicator class: Contains dicePairTotal and dicePairCount. Displaying Results: Sort statIndicators array before display. Indicator objects sortable by dicePairCount (implements Comparable). Example output:-----------------------dicepair rolltotal count percent---- ------ --------7 5 50%10 2 20%4 2 20%2 1 10% Tasks:…Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).C# Write a program named TestScoreList that accepts eight int values representing student test scores. Display each of the values along with a message that indicates how far it is from the average. An example of how the results should be output is as follows: Test # 0: 89 From average: 6Test # 1: 78 From average: -5 using System;using static System.Console;class TestScoreList{static void Main(){// Write your main here}}

Assume that you are implementing the method in a separate file, so you must do proper scope resolution. The calculateAverage() method should calculate and return the average of all the values in the grades array. You may assume there will always be exactly 10 grades in the array, so you can hard-code the number 10 in your solution. Please ONLY implement the calculateAverage() method. Assume that any needed libraries have already been included, and the std namespace is within scope.
