Inheritance and object dependencies: break them down for me.

A wrist watch is one of the most often seen things on the planet. Distinguish how each of the following terminology and ideas relates to the concept of a watch: object; attributes; behaviors; class; inheritance (take the concept of an alarm clock as an example); modeling; messages; encapsulation; interface; and information hiding.

A wristwatch is one of the most often seen objects on the globe. Distinguish the relationship between the following language and concepts and the notion of a watch: object; attributes; behaviors; class; inheritance (as an example, consider the idea of an alarm clock); modeling; messages; encapsulation; interface; and information hiding.

Object models, as well as the concepts of encapsulation and polymorphism, are inexorably intertwined.

how can the relationship between laptop and it's screen can best be categorized? 1. Polymorphism 2. Ownership(Composion, aggregation) 3. Inheritance 4. Binary Association

Answer by true or false 1.An abstract class can contain only abstract methods . 2. An abstract class that extends another abstract class must provide an implementation for all the abstract methods that are defined in the superclass . 3. A parent's constructor can be invoked using the super reference . 4. All Java classes are derived , directly or indirectly , from the Object class . 5. The child of one class can be the parent of one or more other classes .

Write a java program as shown in the following UML class diagram:(read the details below) The classes Name and Date are separate classes used as properties in the Employee class. Class Employee is the superclass of the classes SalariedEmployee and HourlyEmployee. The superclass has the attributes name and data of hire and methods to set and get these attributes. It also has 2 abstract methods equals() which check if the objects are same and toString() which convert the properties to a printable string. Also the method read() which used as an input method. The SalariedEmployee subclass has in addition to the attributes of the super-class the attribute annualSalary and set and get methods for it. This class also defines the read() method and grossPay() which in this case returns the salary of the employee. The HourlyEmployee subclass has in addition to the attributes of the super-class, the hoursWorked and hourlyRate attributes. It provides ‘get’ and ‘set’ methods for these attributes.…

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.
