Answer 1

Answer:

Here is the corrected code:

import java.util.*;

public class DebugNine36 { //class name

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

ArrayList<String>products = new ArrayList<String>(); //creates an ArrayList of type String names products

products.add("shampoo"); //add shampoo to product array list

products.add("moisturizer"); //add moisturizer product array list

products.add("conditioner"); //add conditioner product array list

Collections.sort(products); //sort the elements in products array list

display(products); //calls display method by passing products array list

final String QUIT = "quit"; //declares a variable to quit the program

String entry; //declares a variable to hold product/element or quit

Scanner input = new Scanner(System.in); //creates Scanner object

System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //prompts user to enter a product or enter quit to exit

entry = input.nextLine(); //reads the entry value from user

while(!entry.equals("quit")) { //loops until user enters quit

products.add(entry); //adds entry (product) to products array list

Collections.sort(products); //sorts the elements in products array list

display(products); //calls display method by passing products arraylist

System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //keeps prompting user to enter a product or enter quit to exit

entry = input.nextLine(); } } //reads the entry value from user

public static void display(ArrayList products) { // method to display the list of products

System.out.println("\nThe size of the list is " + products.size()); //displays the size of the array list named products

for(int x = 0; x < products.size(); ++x) //iterates through the arraylist products

System.out.println(products.get(x)); } } //displays each item/element in products array list

Explanation:

In the code the following statement are corrected:

ArrayListproducts = new ArrayList();

This gave an error: cannot find symbol

This is corrected to :

ArrayList<String>products = new ArrayList<String>();

products.add(shampoo);

products.add(moisturizer);

products.add(conditioner);

Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.

This is corrected to :

products.add("shampoo");

products.add("moisturizer");

products.add("conditioner");

display();

This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .

This is corrected to :

display(products);

The screenshot of output is attached.

What is a worksheet?

It is "a piece of paper used to record work schedules, working hours, special instructions, etc. a sheet of paper used to jot down problems, ideas, or the like in draft form." A worksheet used in education could have questions for pupils and spaces for them to record their responses.

A single spreadsheet called an Excel Worksheet is made up of cells arranged in rows and columns. A worksheet always starts in row 1 and column A. A formula, text, or number can be entered into each cell. Additionally, a cell can point to a different cell on the same worksheet, in the same workbook, or in a different workbook.

Therefore, the correct option is D. Use the Sort function to organize the data based on date order.

A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10.

Required:
List different ways that this program can be sabotaged so that during execution it computes a different sum, such as 3 to 20.

Answers

Answer:

See explanation

Explanation:

An instance of such program written in python is

isum = 0

for i in range(1,11):

isum = isum + i

print(sum)

One of the ways the program can give a wrong result is when someone alters the program source program before it's complied and executed.

Take for instance.

Changing

isum = 0 to isum = 4

will alter the result by additional 4

Another way is if an outside program or process alters the program execution.

Write a short quiz program which asks three true/false questions and stores the user's answers as booleans. At the end the program it should print the user's answers with the correct answers.

Note: you should use the same quiz questions and correct answers as the sample run below.

Sample run:

Java is a programming language, true or false?
true
Only numbers can be stored by variables in Java, true or false?
true
There are only 2 possible values which can be held by a boolean variable, true or false?
false
Question 1 - Your answer: true. Correct answer: true
Question 2 - Your answer: true. Correct answer: false
Question 3 - Your answer: false. Correct

The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.

The short quiz program is as follows.

Please note that comments are used to explain difficult lines.

import java.util.*;

public class shortQuiz{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

//This declares the variables that represent correct answers as boolean data type; the variables are also initialized

boolean q1 = true, q2 = false, q3 = true;

//This declares the response to each question as boolean data type

boolean q1response, q2response, q3response;

//This prints the first question

System.out.print("Java is a programming language, true or false? ");

//This gets input for the first response

q1response = input.nextBoolean();

//This prints the second question

System.out.print("Only numbers can be stored by variables in Java, true or false? ");

//This gets input for the second response

q2response = input.nextBoolean();

//This prints the third question

System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");

//This gets input for the third response

q3response = input.nextBoolean();

//This prints your first response, alongside the correct answer to the first question

System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);

//This prints your second response, alongside the correct answer to the second question

System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);

//This prints your third response, alongside the correct answer to the third question

System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);

//The program ends here

}

See attached image for program sample run.

The above program initializes the correct answers using boolean variables. The correct answers are then printed, after the user answers the three questions.

As a twist on the Hello World exercise, you are going to be the end user of the Hello class. This class is designed to greet the user in a variety of world languages. For this task, complete the following:
Use the Scanner class to ask the user for their name.
Create a Hello object by passing the name to the constructor.
Call at least 3 methods from the Hello class to print the greeting in 3 different languages.
Remember to write your code in the HelloTester class, but make sure you take a look at the Hello class so that you know the names of the methods you need to use.

Answers

Answer:

Here is the Hello class:

public class Hello { //class name

private String name; //to store the name

public Hello (String names) //parameterized constructor

{ name = names; }

public void English() { //method to greet user in english

System.out.print("Hello "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } //displays exclamation mark symbol

public void Spanish(){ //method to greet user in spanish

System.out.print("Hola "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } //displays exclamation mark symbol

public void French() { //method to greet user in french

System.out.print("Bonjour "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } } //displays exclamation mark symbol

Explanation:

Here is the HelloTester class:

import java.util.Scanner; //to accept input from user

public class HelloTester { //class name

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

String name; //to store the name of user

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

System.out.println("Enter name?" ); //prompts user to enter name

name = input.nextLine(); //scans and reads the name from user

Hello hello = new Hello(name); //creates Hello class object and calls constructor by passing name

hello.English(); //calls English method using object hello to greet in english

hello.Spanish(); //calls Spanish method using object hello to greet in spanish

hello.French(); } } //calls French method using object hello to greet in french

The output of the program is:

Enter name? user Hello user! Hola user! Bonjour user!
