Calculator Server and Client  Java  The goal: Make a client that sends simple arithmetic expressions, and a server that solves them and sends the result back to the client.  Class design requirements:  Your program should contain at least the following classes • CalculatorClient • CalculatorServer Important note: This is an

This is about java. I would appreciate your help! Please do not provide a “copy and paste answer”!  Among other things, the purpose of this assignment is to assess the student’s ability to write a program dealing with window events, mouse events, and the Delegation Event Model. PROGRAM SPECIFICATIONS Beginning

The following program draws an BB-8 as shown below.  Modify the program to move the BB-8 left or right using the arrow keys.  The program can be download from the CMS. Please use Javafx  import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.input.KeyCode; import javafx.scene.layout.Pane; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.scene.shape.Line; import javafx.stage.Stage;

*This is java programming  Write a main application called Project1.java, and a GUI (that extends JFrame) called WordGUI.java. The main program should open a file called “input.txt” which will contain words, one per line. As the words are read from the file, they should be displayed in the GUI as

 Consider that a school “ABC” hired you as a programmer to maintain the  record of its Students and Teachers. You need to develop a system in C++  to enter the data and show it as and when required. Keeping in the view above scenario, you are required to write a

 Lab Goal : Java – Binary Tree. Will leave an upvote. This lab was designed to teach you more about Binary Trees.  Lab Description : Write a binary search tree class. For the base lab,  you must write the following methods :: preOrder, postOrder, inOrder,  revOrder, getNumLeaves, getNumLevels, getWidth, getHeight,

1. Create a new file called Fraction.java 2. In this file, create a class Fraction.  a. This class should have 2 attributes, declare it, don’t forget those fields/attributes need to be private b. Create 2 constructors, i. One constructor without any parameter. This constructor will initialize the first attribute to

The language used is Java /**  *   * Merging k sorted arrays into a single sorted array.  * Your algorithm must be stable.  *   * You are NOT allowed to call the constructor of class Student, except in <em>main</em>.  */ public class StableMerger {     /**      *       * No modification to

 Convert User Input to an Array of KivaCommands The  RemoteControl class currently takes in a String of commands from the  user that looks like “FFFTRF”. However, our Kiva robots cannot  understand instructions in that form. They can simply make one move at a  time, accepting a single KivaCommand. So, we’ll

Mutex  locks and semaphores, as discussed in class, are different techniques to  solve the race condition and to ensure an efficient synchronization  between cooperating threads and processes. you will use semaphores to  solve a number of synchronization problems between cooperating threads. important to note that: •  Semaphore, in literature, uses

For this project, you are going to write a program to find the anagrams in a given dictionary for a given word. If two words have the same letters but in different order, they are called anagrams. For example, “listen” and “silent” are a pair of anagrams. **JAVA** First let’s

Triangle 2.0 (The name is a hint) Description: For  the task we’ll build a class representing a Rectangle. The tests for  this task will not check what’s happening inside the class you create,  so it’s up to you as to what data members you use. The tests will also  assume

Question: Basic java please help  QUESTION 1: Add code to ask user about the number of players (from 1 to 3) – use game.askForInt. Store the input in a variable numPlayers. QUESTION 2: Modify the code below to ask for players’ names and add them to the game in a

 make a University  app to have a simple system to keep track of all the students (graduate  and undergrads).To do that the following classes are needed for this  object-oriented database. Student StudentID : Integer stdFirstName: String stdLastName: String stdMarks : Double [] stdAddress: Address ** Class Student should have set/get

complete the method named countdown (method  stub provided) so that it accepts an int countFrom as its parameter and  prints each number from countFrom to 1 on a single line separated by a  space. This method should not return anything (void return type). Hint:  Use a loop and think about

This  assignment lets you build a set of classes to support a program to find  paths through a cave. By the end of Unit 4, you will have a program that  can read a 2-dimensional cave layout from a file, search the layout to  find a path to a mirror

(Financial application: compute the future  investment value) Write a method that computes future investment value  at a given interest rate for a specified number of years. The future  investment is determined using the formula in Programming Exercise 2.21.  Use the following method header: public static double  futureInvestmentValue(double investmentAmount, double  monthlyInterestRate,

Task 2: Text Counter (USING JAVAFX) Develop a class TextCounter that extends javafx.scene.text.Text and implements Runnable. Your layout should appear similar to the image below.  Next, develop a class IntCounter that has an integer counter intialised to 0, and methods incrementCount, getCount and setCount.  For this application, create Start, Pause
