In Java, we use inheritance for "is-a" relationships. Containment, on the other hand, indicates that one object has another object. These are "has-a" relationships. For the following relationships, determine if they are a "is-a" or a "has-a" relationship: o bicycle - vehicle o car - engine o pizza - topping o food - pizza o dog - mammal 2. Share with someone else 3 other examples for each of the following relationships: o Inheritance ("is-a" relationship) o Containment ("has-a" relationship) 3. public class PersonInfo { protected String firstName; protected String birthdate; } public class ChildInfo extends PersonInfo { private String schoolName; } public class MotherInfo extends PersonInfo { private String spousename; private ChildInfo children1; private ChildInfo children2; private ChildInfo children3; ... } A.

Make a class Executive inherit from Manager. Implement toString and equals methods for all classes; supply a test program that tests these classes and methods toString() method should print all the properties of the class; as Name and DOB is same for both student and instructor, you can implement it in the superclass "Person" Problem 1 Create 3 students Student1 : Name James, DOB: 01/01/2000, Major: English Student2: Name Jane, DOB:…arrow_forward
- Consider the following detailed inheritance hierarchy diagram: (ATTACHED IN IMAGE) The person constructor has two string parameters, a first name, and the last name. The constructor initializes the e-mail address to the first letter of the first name followed by the first five letters of the last name followed by @jc.com. If the last name has fewer than five letters, the e-mail address will be the first letter of the first name followed by the entire late name followed by @jc.com A) Implement the person constructor: B) Override Object's toString method for the Person class. The toString method should return the present state of the object. Assume that the constructor writer for the previous part of this problem works as intended. C) Write both the Person and Student class headers so that the Student is a subclass of Person.arrow_forwardConsider the following detailed inheritance hierarchy diagram: (ATTACHED IN IMAGE) The person constructor has two string parameters, a first name, and the last name.

The Money class represents an amount in U.S. dollars. Money Class e Fields cents : int dollars : int e Methods getValue() : double Money(int d, int c) setCents(int c) : void setDollars(int d) : void toString() : String • Each Money object has two int instance variables: dollars and cents. • The class has one constructor that takes two int parameters. The first int represents whole dollars, and the second int represents cents. • The class has one accessor method named getValue() which returns the amount as a double. (Just divide cents by 100.0 and add it to dollars. Return that amount.) • The class has two mutator methods-setDollars() and setCents()–that modify the corresponding instance variables. • The class has a toString() method that returns the amount as a String in the form: $ 2345.75. Use concatenation to produce the output. Do not worry about the decimal places.arrow_forward
