A: Actually, UML stands for Unified Modeling Language.
- Design a new Triangle class that extends the abstract GeometricObject class:
- Draw the UML diagram for the classes Triangle and GeometricObject
- Implement the Triangle class
- Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled:
- The program should create a Triangle object with these sides and set the color and filled properties using the input
- The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not

Car and truck both have fuel quantity, fuel consumption in liters per km and can be driven givendistance and refueled with given liters. But in the summer both vehicles use air conditioner and their fuelconsumption per km is increased by 0.9 liters for the car and with 1.6 liters for the truck. Also the truck has a tinyhole in his tank and when it gets refueled it gets only 95% of given fuel. The car has no problems when refueling andadds all given fuel to its tank. If vehicle cannot travel given distance its fuel does not change.Input On the first line - information about the car in format {Car {fuel quantity} {liters per km}} On the second line – info about the truck in format {Truck {fuel quantity} {liters per km}} On third line - number of commands N that will be given on the next N lines On the next N lines –…JAVA CODE PLEASE THANK YOU Rectangle by CodeChum Admin A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0,0), the bottom right corner of the console is point (MAX, MAX) and given two points (all "x" and "y" coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class for a point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the sample area() - computes and returns the area of a given rectangle perimeter() - computes and returns the perimeter of a given rectangle…The following declaration, program, and program segment has errors. Locate as many as you can. class Circle: { private double centerX; double centerY; double radius; public setCenter(double, double); setRadius(double);}
- The Spider Game Introduction: In this assignment you will be implementing a game that simulates a spider hunting for food using python. The game is played on a varying size grid board. The player controls a spider. The spider, being a fast creature, moves in the pattern that emulates a knight from the game of chess. There is also an ant that slowly moves across the board, taking steps of one square in one of the eight directions. The spider's goal is to eat the ant by entering the square it currently occupies, at which point another ant begins moving across the board from a random starting location. Game Definition: The above Figure illustrates the game. The yellow box shows the location of the spider. The green box is the current location of the ant. The blue boxes are the possible moves the spider could make. The red arrow shows the direction that the ant is moving - which, in this case, is the horizontal X-direction. When the ant is eaten, a new ant is randomly placed on one of the…Assignment Description This program will simulate part of the game of Yahtzee! This is a dice game that involves rolling five dice and scoring points based on what show up on those five dice. The players would record their scores on a score card, and then total them up, and the player with the larger total wins the game. A Yahtzee score card has two portions: The upper portion has spaces for six scores, obtained by adding up all of the 1's, 2's, 3's, etc. The lower portion has special scores for various combinations: Three of a kind -- at least 3 dice are the same number;the score is the sum of all five dice Four of a kind -- at least 4 dice are the same number;the score is the sum of all five dice Small straight -- four consecutive numbers are represented, e.g. 2345;the score is 25 points Large straight -- five consecutive numbers are represented, e.g. 23456;the score is 30 points Full House -- three of one kind, two of another; the score is 30 points Yahtzee! -- five of a kind; the…Object-Oriented Programming Assignment #3 A complex number is a number in the form a + bi, where a and b are real numbers and į is V-1.

- Rolling Dice Simulator [Java Assignment]Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle.

- Transcribed Image Text JAVA Programming Problem: In the game of "Assassin's Creed", you control a ship with a cannon which is attacking a large enemy Assassin's Creed, armed with many guns. Your goal is to destroy as many of the guns as possible. The battle field is a 2D Cartesian grid, where your cannon is located at the origin. The enemy Assassin's Creed is a horizontal line segment located from the coordinates (X1, Y) to (X2, Y). There are exactly (X2 - X1 + 1) guns on the ship, located at the integer points (X1, Y), (X1+1, Y), ..., (X2, Y). However, the problem is, you cannot always fire at a gun. There are supernatural rocks located at all points of the battlefield whose X and Y coordinates are both integers. In order to fire successfully at an enemy's gun, the line connecting your cannon and that gun must not go through any rocks. Develop a JAVA code to output the number of the enemy battleship's guns that your cannon can destroy.
