Question 3: (Inheritance)

Create an abstract class called Employee that has an abstract method call computePay() which

computes the total pay per employee using the rate per hour = $50. The method should accept

the number of hours the employee has worked. Create a child class called employeeChild and

provide the implementation. In the main method invoke that method and get the number of hours

worked from the user and pass it to the called method.

Question 2 (Polymorphism)

Mathematically, the area of a rectangle is computed as length * width, the area of a circle is

computed as pi*radius*radius. Given that pi = 3.14, write a Java program with an overloaded

method called getArea() that can compute for the area of a circle or rectangle depending on the

parameters supplied. Illustrate how you will invoke the method in the main method for the two

scenarios.

You’re working on a search engine. Watch your back Google!

The given code takes a text and a word as input and passes them to a function called search().

The search() function should return "Word found" if the word is present in the text, or "Word not found", if it’s not.

Sample Input

"This is awesome"

"awesome"

Sample Output

Word found

Develop a Python application that will randomly select n integers from 1 to 45 without repetitions.

Sample Output 1:

How many numbers? 6 6 randomly selected nos. [21, 35, 16, 36, 5, 8]

Question 1: (Inheritance)

Consider a scenario where you have been given three classes, namely Vehicle, Bus, and

School_Bus. The School_Bus class is supposed to inherit all characteristics of both the Vehicle

and the Bus class. Explain and illustrate how you are going to achieve this considering you are using Java programming language.

Solve the following problem by showing the design of your solution as an algorithm.

The problem – The program will take two integers from the user, say n1 and n2. It will then print the sum of all numbers between n1 and n2, inclusive. For example, if the user enters 5 and 9, the program will print the value of 5+6+7+8+9. On the other hand, if the user enters 5 and -2, the program will print the value of 5+4+3+2+1+0+(-1)+(-2). Note: Do not assume the user will always enter the smaller number first.

Develop a Python application that will accept two non-negative integers and store them in a list and will append ten additional values equivalent to the sum of the two previous elements of the list.

Sample Output:

First Number: 1

Second Number: 3

[1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322]
