Example of Inheritance: Circle-Cylinder, the Circle is the super class of Cylinder. The Cylinder class is the sub-class of Circle. class Cylinder extends Circle { double height; public class Circle { int xcenter; int ycenter; double radius; Circle( ) { this(1.0); } Cylinder() { super(); height=1.0; } int y, double r, Circle(int x, int y, double r) { xcenter = x; ycenter = y; radius = r; } Cylinder(int X double h) { super(x, y, r); height=h; } Circle( double r){ this(0, 0, r); } Cylinder(int h){ height = h; } double findArea() { return 3.14*radius*radius; } double findVolume() { return super.findArea() *height; } } double findDiameter() { return 2*radius; } } http://hilite.me converts your code snippets into pretty-printed HTML format, easily embeddable into blog posts, emails, and websites. 3.6 Unified Modeling Language (UML) UML is a standard way to represent the class's skeleton. It is represented with a table of 3 rows: the first row: title, the second row: properties, and the third row: constructors and methods. As shown below, Eclipse IDE has an outline panel to represent UML. Person Description name: Name dateOfBirth: Date - numPerson-0: int Name of Person Date of Birth of Person Number of Person A Properties Outline x Person name: Name A dateOfBirth: Date Anum Person: int Person(String, String, int, int, int) A printinfo() : void A printAgeAtYear(int) : void A $ printNumberOfPerson : void +Person(firstName: String. lastName:String, day:int, int month:int, year: int) A constructor with 5 arguments. The constructor assigns input arguments into their corresponding properties eclipse Constructor + printinfo():void Method Print information of a person in the following format: Name: firstName lastName DOB: day-month-year Age: age printAge AtYear(int year):void Print the age of a person at input year in the format of Age: age + printNumberOfPerson():void Print the number of Persons in the following format The total number of Persons is numPerson Exercise 1: (2 points) Project Name : _LAB03_ CompanyHierarchy Instruction : Complete a class Person provided in a template using the given UML. Remark: Students should re-uses Java classes: Name.java, Date.java from Google Classroom. Person Description name: Name dateOfBirth: Date numPerson=0: int Name of Person Date of Birth of Person Number of Person Person(firstName: String, lastName: String, day:int, month:int, year:int) A constructor with 5 arguments. The constructor assigns input arguments into their corresponding properties printInfo():void Print information of a Person in the following format: Name: firstName lastName DOB: day-month-year Age: age printAgeAtYear(int year):void Print the age of a Person at input year in the format of Age: age print NumberOfPerson (:void Print the number of Persons in the following format The total number of Persons is num Person. mer Exercise 2: (2 points) Project Name Instruction : _LAB03_ Company Hierarchy : Complete a class Employee provided in a template using the given UML.
