Alisiya [41]

Maturity Stage – During the maturity stage, the product is established and the aim for the manufacturer is now to maintain the market share they have built up. This is probably the most competitive time for most products and businesses need to invest wisely in any marketing they undertake. They also need to consider any product modifications or improvements to the production process which might give them a competitive advantage. i think this would be the best time for the company to purchase an emerging technology.

klio [65]

Answer: D) Whitelisting

Explanation:

Whitelisting are used in many applications and it only allows the good known apps. Whitelisting are majorly used for security purpose as, it permits to maintain or control the misuse the apps by employees in an organisation.

Blacklisting maintain the list of denied access system and it prevented the accessing undesirable program. It is also used as security application but it is less effective than whitelisting.

Encryption are the process which are not used in the restricting application. And lockout are used by the users for entering the password for many time as possible.

Therefore, option (A) is correct.

2. Write a program that calls creates an ArrayList of integer and calls the method minToFront described below. Print out the lis

Novosadov [1.4K]

Answer:

import java.util.ArrayList;

public class MinToFront {

public static void minToFront(ArrayList < Integer > list){

int miniIndex = 0;

for(int j=1; j<list.size(); j++){

if(list.get(miniIndex) > list.get(j))

miniIndex = j;

}

// moving min to front

int min = list.get(miniIndex);

list.remove(miniIndex);

list.add(0, min);

}

public static void main(String[] args) {

ArrayList<Integer> list = new ArrayList<>();

list.add(4); //value store in list

list.add(7); //value store in list

list.add(9); //value store in list

list.add(2); //value store in list

list.add(7); //value store in list

list.add(5); //value store in list

list.add(3); //value store in list

list.add(5); //value store in list

list.add(1); //value store in list

list.add(7); //value store in list

list.add(8); //value store in list

list.add(6); //value store in list

list.add(7); //value store in list

System.out.println(list);

minToFront(list);

System.out.println(list);

}

Output:

[1, 4, 7, 9, 2, 7, 7, 5, 3, 5, 7, 8, 6, 7]

Explanation:

Firstly,we define a method minToFront(), than set an integer variable "miniIndex" to 0, than set a for loop and apply the following condition and inside the loop we apply the if condition, set an integer variable "min" in which we store the value and than we set the following list [4, 7, 9, 2, 7, 7, 5, 3, 5, 1, 7, 8, 6, 7], after that print the list and than print an output.

(Displaying a Sentence with Its Words Reversed) Write an application that inputs a line of text, tokenizes the line with String

Serjik [45]

Answer:

I am writing a JAVA and Python program. Let me know if you want the program in some other programming language.

import java.util.Scanner; // class for taking input from user

public class Reverse{ //class to reverse a sentence

public static void main(String[] args) { //start of main() function body

Scanner input = new Scanner(System.in); //create a Scanner class object

System.out.print("Enter a sentence: "); //prompts user to enter a sentence

String sentence = input.nextLine(); // scans and reads input sentence

String[] tokens = sentence.split(" "); // split the sentence into tokens using split() method and a space as delimiter

for (int i = tokens.length - 1; i >= 0; i--) { //loop that iterates through the tokens of the sentence in reverse order

System.out.println(tokens[i]); } } } // print the sentence tokens in reverse order

Explanation:

In JAVA program the user is asked to input a sentence. The sentence is then broken into tokens using split() method. split method returns an array of strings after splitting or breaking the sentence based on the delimiter. Here the delimiter used is space characters. So split() method splits the sentence into tokens based on the space as delimiter to separate the words in the sentence. Next the for loop is used to iterate through the tokens as following:

Suppose the input sentence is "How are you"

After split() method it becomes:

How

are

you

Next the loop has a variable i which initialized to the tokens.length-1. This loop will continue to execute till the value of i remains greater than or equals to 0.

for (int i = tokens.length - 1; i >= 0; i--)

The length of first token i.e you is 3 so the loop executes and prints the word you.

Then at next iteration the value of i is decremented by 1 and now it points at the token are and prints the word are

Next iteration the value of i is again decremented by i and it prints the word How.

This can be achieved in Python as:

def reverse(sentence):

rev_tokens = ' '.join(reversed(sentence.split(' ')))

return rev_tokens

line = input("enter a sentence: ")

print((reverse(line)))

The method reverse takes a sentence as parameter. Then rev_tokens = ' '.join(reversed(sentence.split(' '))) statement first splits the sentence into array of words/tokens using space as a delimiter. Next reversed() method returns the reversed sentence. Next the join() method join the reversed words of the sentence using a space separator ' '.join(). If you want to represent the reversed tokens each in a separate line then change the above statement as follows:

rev_tokens = '\n'.join(reversed(sentence.split(' ')))

Here the join method joins the reversed words separating them with a new line.

Simply input a line of text and call this reverse() method by passing the input line to it.
