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().

- Java Programming Problem 2 – Message Encoder, Decoder Create an interface MessageEncoder that has a single abstract method encode(plainText), where plainText is the message to be encoded. The method will return the encoded message. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described above. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. Defne the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.) Create a class ShuffleCipher that implements the interface MessageEncoder, as described above. The constructor should have one parameter called n. Define the method encode so that the message is shuffled n times. To perform one shuffle, split the message…UML Diagrams: Course -courseName: String -students: Student [] -numberOfStudents: int +Course(courseName : String) +getCourseName() : String +addStudent (student : Student) : void +addStudent (studentName: String): void +dropStudent(studentId: int ) : void +getStudents() : Student [] +getNumberOfStudents() : int a.

- Javascript Part 1 Design a Monster class. A Monster is created with a language argument string and a stomach represented by an array. The Monster should support functions eat() and speak(). Use the class notation to define your Monster object's interface. eat(food) will store the passed argument into its stomach and return what it has eaten thus far. speak(sentence) will simply return the passed in phrase. class Monster(language) {constructor(language){// set language}// takes a food_item STRING and returns everything eaten so far ARRAYeat(food_item) {// ... complete }// takes in a sentence STRING and returns the passed in sentence STRING with no changespeak(sentence) {// ... complete}} Part 2 Create an object, Gremlin, that extends the Monster interface and takes the same argument language. Gremlins inherits how a monster eats. Gremlins speaks differently. Gremlins replace each word in a sentence with its only known language, "gar". For example, if the sentence is "I like chicken",…Consider a system namely, Student Information System (SMP) in which one of its class is Course. class Course { char course_name[30]; char course_code [10]; char course_type [10]; int credit hour; int total creditHour; public: void Register Course ();//to input course registration information void DropCourse ();//to drop course that has been registered void ViewAvailableCourse ();//to view the available courses float CalculateTotalCredit Hour (); //to calculate total credit hours void PrintRegisteredCourse ();//to print course registered }; Constraint: 1.

- Project in Java programming language : Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.Computer ScienceQuestion: Draw a sequence diagram to illustrate the interaction that takes place between the Client, the TumbleDryer and Bosch objects, and System.out when the describe() message is sent.
