Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays an appropriate message.

Answer:

Public and private keys form the basis for public key cryptography, also known as asymmetric cryptography. In public key cryptography, every public key corresponds to only one private key. Together, they are used to encrypt and decrypt messages. If you encode a message using a person’s public key, they can decode it using their matching private key.

Three steps can be taken to construct a list of elements using a for loop: Make an empty list appear. Iterate through an iterable or set of elements. Add each component to the list's end.

An Array List can be looped through using an Iterator. If there are additional members in the Array List, the method hasNext() returns true; otherwise, it returns false. If there is no next element, the method next() raises the No Such Element Exception and returns the next element in the Array List.

FOR LOOPS and WHILE LOOPS are two popular types of loops. A For loop runs a variable number of times. LOOP TYPE — FOR LOOP When you know how many times you want to run an algorithm before stopping, you use for loops.

Therefore, Since indexation in lists begins at 0, we must compare item[0], which is “male,” with “male” in the if statement before iterating through males in the for loop.

Explanation:

D

Yvonne will most likely worry that the mat will discolor and deteriorate. The correct option is D.

Lists are used in Python to hold multiple values in one variable

(a) Nested list

A nested list is simply a list of list; i.e. a list that contains another list.

It is also called a 2 dimensional list.

An example is:

nested_list = [[ 1, 2, 3, 4]  , [ 5, 6, 7]]

(b) The “*” operator

The "*" operator is used to calculate the product of numerical values.

An example is:

num1 = num2 * num3

List slices

This is used to get some parts of a list; it is done using the ":" sign

Take for instance, you want to get the elements from the 3rd to the 5th index of a list

An example is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

secondList = firstList[2:5]

The “+=” operator

This is used to add and assign values to variables

An example is:

num1 = 5

num2 = 3

num2 += num1

A list filter

This is used to return some elements of a list based on certain condition called filter.

An example that prints the even elements of a list is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

print(list(filter(lambda x: x % 2 == 0, firstList)))

A valid but wrong list operation

The following operation is to return a single list, but instead it returns as many lists as possible

def oneList(x, myList=[]):

   myList.append(x)

   print(myList)

oneList(3)

oneList(4)

Programming languages can be used to simulate several scenarios; in this case, the "boost"

The simulating program in C++ where comments are used to explain each line is as follows:

#include<iostream>

#include<cstdlib>

#include<ctime>

using namespace std;

int main() {

 // This sets the seed to time(0)

 srand(time(0));

 // This generates a random number between 0 and 10, to represent the boost

 int boost = rand()%10;

 // This prints the required outputs

 cout << "Boost: " << boost;

 cout << "\nDistance travelled: " << boost;

We are given that;

- Game changer technologies has four software teams

- Each of the teams develops 4 different examples of the new game app.

Now, since each of them is developing four four different examples of its new game app, the method being used is called prototyping. This is because prototyping is referred to as the early approximation of the final system of a product whereby such a product is built, tested and rebuilt if required until an acceptable prototype is achieved.

When the acceptable prototype is gotten, then it will be used to develop its final game app.
