Can you help with the code and explanation comments? You should design a Skyscraper class, with private variables representing the state (i.e., theboard configuration) as well as the following methods:1. public boolean verifyPlacement() – this method should return true if the place-ment is valid (i.e., every row and every column contains each number exactly once.).Otherwise, this method should return false.2. public void loadPuzzle()in the format specified below. This method must update the relevant instance variablesfor the object.3. public void print()lowing the format specified below.4. public void printWithVisibility()with the visibility scores on the outside.5. A very simple main method which loads the puzzle from the user, then checks validityand prints the result. If it's valid, it also prints the puzzle with visibility.this method should read a puzzle from standard inputthis method should print the puzzle to standard output fol-this method should print the puzzle along 2.1Input and Output FormatThe loadPuzzle() method reads the configuration from standard input. This is the formatof the input and the required output for basic printing:1. The first line contains the square dimension of the board, DIM, as a single integer.2. The remaining DIM lines will each contain exactly DIM positive integers, separated bya single space, but with no trailing space after the last integer. These lines representthe heights of the skyscrapers in the same layout as the puzzle.3. All subsequent lines should be ignored.For example, the puzzle in Figure 3 is described by the input:44 3 2 11 4 3 23 2 1 42 1 4 32.1.1 printWithVisibility FormatThe printWithVisibility method should output a graphical representation of the puzzle,along with the visibility scores calculated according to the rules described earlier.For the puzzle in Figure 3, the output of this method should be:1 2 3 3114 3 2 1|42|1 4 3 2|3213 2 1 4|12|2 1 4 3|23 3 1 22.2 Design and DocumentationYou are required to have exactly the public methods described in this document. You arealso encouraged (but not required) to have helper methods. (These may be particularlyhelpful when verifying the puzzle and when calculating visibility.) All your helper methodsshould be declared private. If you have any class variables, they must be declared privateas well.Because it complicates grading, you are not allowed to have any package declarations. In-cluding package declarations in your submission will cause you to lose points.As with all Java programs, your program filename must match the public class exactly,therefore your program must be named Skyscraper.java and your class name must benamed Skyscraper.

Problem: Bugs are simple creatures that only know how to walk towards other bugs. Bugs maintain information about their (x, y) position; by which it can tell if they are standing next to other bugs. Watch the following video: bug movement. Create a java project that simulate bugs movement. You need to write a class “Bug" that models a bug moving along a straight line and it can turn to change its direction counterclockwise (i.e. 90 degree to the left; north → west → south → east → north). In each move, its position changes by one unit in the current direction. Details of the "Bug" class is described below. Your simulator should read information of an unknown number of “Bug" objects from an input file called “Bugs.txt". Each line represents a bug and the initial position and facing direction of this particular bug. Keeping the first bug position as a reference the simulator should move the second bug next to the first bug forming a cluster and its final position and direction should be…

Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. (Java)

Define the Circle2DYourLastName class that contains: Two double data fields names x and y that specify the center of the circle withgetter methods. A double data field radius with getter method. A constructor that creates a circle with specified x, y, and radius. A method findTypeOfIntersection to determine and return types ofintersection as string (contained, overlap, or separate).Design a user class that prompts the user to enter the coordinates of the center andradius of two circles and displays the type of intersection. Allow the user to repeat yourprogram using a ConfirmDialog Box.
Create a RightTriangle class given the following design: RightTriangle variables: base, height methods: 2 constructors, 1 that set default values and another that accepts to parameters. setBase - changes the base. Requires one parameter for base. setHeight - changes the height. Requires one parameter for height. getBase - returns the triangle base. getHeight - returns the triangle height. area - returns the area of the triangle (1/2bh) given the current base and height
Eclipise Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:
Rules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().
The Factory method design pattern is useful since it can be used to create new objects of a particular type dynamically. True False
