Answer:

a. Object cannot be converted to Person

Explanation:

This program demonstrates polymorphism.

e.g., a Student IS a Person therefore you can call m() with a Student as well as a Person object.

The same goes for GraduateStudent.

However, and Object is not a Person, so the last call fails. This can be deducted by the type checking that happens at compile time.

Applying given information of a computational language in pseudocode, a code may be written to represent computing the price of an item on sale for 10% off.

<h3>What is a pseudocode?</h3>

A pseudocode can be considered as a depiction of the steps represented in an algorithm, usually in plain (natural) language.

//This pseudocode is intended to describe

//computing the price of an item on sale for 10% off

START

input origPrice

discount = origPrice * 0.10

finalPrice = origPrice - discount

output finalPrice

STOP

//This pseudocode is intended to compute the number

//of miles per gallon you get with your car.

START

input milesTraveled

input gallonsOfGasUsed

milesPerGallon = milesTraveled / gallonsOfGasUsed

//milesPerGallon is computed using division

output milesPerGallon

//miles is misspelled, and the P in milesPerGallon should be uppercase

STOP

//Program should end with stop

//This pseudocode is intended to describe

//computing the per day cost of your rent

//in a 30-day month

START

input rent

costPerDay = rent / 30

// Comment indicates 31-day month

output costPerDay

// output should be costPerDay

STOP

Explanation:

demo.java Shapes 2 Shapes Polymorphism Create a set of classes derived from an abstract class Shape, which provides a common interface, for managing various 2D geometric shapes. In our model, each Java object will represent a shape somewhere in a Cartesian coordinate system. However, note that unlike in Mathematics, the positive y-axis grows down from the origin. Shapes All shapes have the following properties: color, area, perimeter, location, and bounds. Shapes are mutable, for example any shape can be moved.

(a) There will be a need for the database to support a comparatively complex and complicated hierarchical internal record structure that may vary for each record. Column store NoSQL DBMS

(b)The key requirements for the database are to access a specific record structure as quickly as possible without any concern regarding the internal structure of the record. Key value store NoSQL DBMS

(c) The data are specifically well suited to be organized as a network of connections amid the data items. Graph Base NoSQL DBMS

(d) It is essential that the DBMS offers quick access to each of the records by a key value, but, in addition, it has to also allow easy access to the components of each record. Document store NoSQL DBMS
