Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

• Instantiate an Animal array
• Fill it with 2 subclasses of Animal - Owl, Monkey
• For each animal, call all 4 methods - printInfo, printInfoSleep,
printFeed, printRoam
• Call the printClimb method of the Monkey
• Hint: Casting

Task 1.1: Base Animai
Create Animal Class with 3 protected attributes:
• name - String
• type-String
• nocturnal - boolean
• 4 public void Methods:
• printInfo-should print:
"<name> is a(n) <type>."
• printSleepInfo-should print:
"<type>s sleep during day." or "<type>s sleep during night."
• printRoam - should print:
"<name> walks around."
• printFeed method - will implement in subclasses
●
Subclass Owl:
Constructor takes in name as argument and sets
the attributes:
• Type should be "Owl", nocturnal should be true
and name is given as the argument
ia
printFeed method:
• Should print "You give <name> some mice."
Overriding roam method:
• Should print "<name> flies around."
Subclass Monkey:
• Similar constructor:
• Type should be "Monkey", nocturnal should be
false and name is given as the argument
printFeed method:
Should print "You give <name> some bananas."
Create another public method called printClimb:
Should print "<name> climbs a tree!"

Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…
USING JAVA: Part A) Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An Appointment has a description (for example, “See the dentist”) and a date. Write a method, occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.
-Interface IResearch Scholar has two methods public void teaches (String str) and public void studies (String str). - Define classes JuniorRS and SeniorRs such that JuniorRS implements IResearchScholar and SeniorRS extends JuniorRS. - Class InterAbstrTest extends SeniorRS, and has the main method. An object of JuniorRs invokes the method studies, and an object of SeniorRS invokes methods studies and teaches.
Goal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class The Recipe constructors so far did not specify how many servings the recipe is for. We will now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (see sample output below for an…
In java Define and create an array (called emps) of object references for objects of class Employee of length 100. (b) Create three objects for classes SalariedEmp, WeeklyEmp, and HourlyEmp (where these 3 classes are subclasses of class Employee); and with references e1, e2, e3 for the 3 objects:(c) Assign e1,e2, e3 to the first three elements of array emps:(d) Print the earnings of the 100 employee in the array emps in one loop (with polymorphism) where earnings are calculated with method earnings():
The Delicious class – iterative methods The Delicious class must:• Define a method called setDetails which has the following header: public void setDetails(String name, int price, boolean available) This must find in the ArrayList the Chicken with the given name, change itspricePerKilo to the given price parameter and set whether it is in stock or not. A value of true for the available parameter means the chicken is in stock and a value of false means it is sold out (not in stock). Note that there will only be at most one Chicken object of the given name stored in the ArrayList.• Define a method called removeChicken that takes a single String parameter representing a chicken’s name. This method must remove from the ArrayList the Chicken object (if any) with the given name. The method must return true if a cheese with the given name was found and removed, and false otherwise.The Delicious class – challenge method In the Delicious class complete the findClosestAvailable method: This…
3. Design a user-defined class called Course. Each course object will hold data about a course. The data includes courseID, courseName, credits and instructorName. Define the instance variables required of the appropriate type. Provide only get methods along with toString() and equals() methods. Design another user-defined class called Student. Each student object will hold data on name, GPA and courseList. Make sure to define courseList as an ArrayList holding references to Course objects Implement a constructor that will take values to initialize name, and gpa while courseList is initialized to an ArrayList() object. Provide the following get methods: getStudent ID ( ), getName(), getGPA (), get Gender(), and get CourseList() Note: the getCouresList() method will return a copy of the coureList arraylist with copies of course objects. Provide the following set methods: setName(), setGPA (), setGender() Another method: addCourse () that will take a Course object and add it to the…
Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)

Javascript 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", the speak() method will turn it into "gar gar gar". class Monster { constructor(language){ this.language = language; this.stomach = Array(); } // takes a food_item STRING and returns everything eaten so far ARRAY eat(food_item) { this.stomach.push(food_item); } // takes in a sentence STRING and returns the passed in sentence STRING with no change speak(sentence) { returnsentence; } }
