5. Assume that Person is a predefined class and that the declaration Person[] people; has already been performed. Then the instruction People = new Person [200]; Reserves memory space for(Circle the answer): Option 1: a single Person object Option 2: 200 Person objects Option 3: a single reference variable that points to a single Person object Option 4:200 reference variables and 200 Person objects Option 5: 200 reference variable, each of which can point to...

Define a class named ComparableNames thats extends Person and
implements comparable
Define a class named ComparableNames that extends Person (defined below) and implements Comparable. Override the compare To method to compare the person on the basis of name. Write a test class to find the order of two ComparableNames. class Person String name; Person00 Person(String n) name=n: Hint: in class ComparableName, you only need a constructor with arg to initialize the data filed defined in the super class...

Design a Java class for Person with the following behaviours: • talk, in which a person can talk a sentence, if s/he is at least two-year old. • eat, in which a person can eat something if s/he is hungry. If the person eats something, then s/he becomes full (not hungry). • needFood, in which the person’s status will become hungry if s/he is currently full. • walk, in which a person will walk a specific distance. If a person...
Show how a class and a method are defined, how the method is called, and how it can return a value. Remember that you need to create an object of the class before you can call its methods. You should create your class and call its method in another class that has a main method.
C++, entry level no pointers or vectors. Write a class called Person that has two data members - a string variable called name and a double variable called age. It should have a constructor that takes two values and uses them to initialize the data members. It should have get methods for both data members (getName and getAge), but doesn't need any set methods. Write a separate function (not part of the Person class) called stdDev that takes two parameters...
Java Program (PLEASE PROVIDE SCREENSHOT OF THE CODE) Create a class Person which is a super class. The class includes four private String instance variables: first name, last name, social security number, and state. Write a constructor and get methods for each instance variable. Also, add a toString method to print the details of the person. After that create a class Teacher which extends the class, Person. Add a private instance variable to store number of courses. Write a constructor...

Define an interface FarmAnimal that contains two methods: getName() and talk(), each returns a string. Declare an abstract class FarmAnimalBase that implements the interface FarmAnimal. In the class FarmAnimalBase, define a private final instance variable name (type: String), a public constructor that initializes the value of the instance variable name, and a public method getName() that returns the value of the instance variable name. Note that we do not implement the method talk() declared in the interface FarmAnimal, that’s the...
in java • Create an interface called Person. In this interface create a method called printData() • Implement interface Person by classes Student, Teacher, Admin. You need to think the relevant data attributes for each class. Define atleast 4 attributes for each class. • In each class override a method toString() and create a string which holds all data • In the method printData in each class print the data using toString() method. Design the UML and write a code...
