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.

// This pseudocode is intended to describe
ddd [48]

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.

<em>//This </em><em>pseudocode </em><em>is intended to describe</em>

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

<em>START</em>

<em>  input origPrice</em>

<em>  </em><em>discount </em><em>= origPrice * 0.10</em>

<em>  </em><em>finalPrice </em><em>= origPrice - discount</em>

<em>  output finalPrice</em>

<em>STOP</em>

<em>//This pseudocode is intended to </em><em>compute </em><em>the number</em>

<em>//of miles per </em><em>gallon </em><em>you get with your car.</em>

<em>START</em>

<em>  input milesTraveled</em>

<em>  input gallonsOfGasUsed</em>

<em>  milesPerGallon = milesTraveled / gallonsOfGasUsed</em>

<em>     //milesPerGallon is computed using </em><em>division</em>

<em>  output milesPerGallon</em>

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

<em>STOP</em>

<em>  //</em><em>Program </em><em>should end with stop</em>

<em>//This pseudocode is intended to describe</em>

<em>//computing the </em><em>per day cost </em><em>of your rent</em>

<em>//in a 30-day month</em>

<em>START</em>

<em>  input rent</em>

<em>  costPerDay = rent / 30</em>

<em>     // Comment indicates 31-day month</em>

<em>  output costPerDay</em>

<em>     // output should be </em><em>costPerDay</em>

<em>STOP</em>

Virty [35]

Answer:

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.
