In this exercise you will debug the code which has been provided in the starter file. The code is intended to do the following:

abruzzese [7]

Answer:

The corrected code is as follows:

import java.util.Scanner;

public class U2_L4_Activity_Two{

public static void main(String[] args){

Scanner scan = new Scanner(System.in);

String str1 = scan.nextLine();

String str2 = str1;

str1 = str1.toUpperCase();

System.out.println(str1);

System.out.println(str2);

}

Explanation:

This corrects the scanner object

Scanner scan = new Scanner(System.in);

This line is correct

String str1 = scan.nextLine();

This copies str1 to str2

String str2 = str1;

This converts str1 to upper case

str1 = str1.toUpperCase();

This prints str1

System.out.println(str1);

This prints str2

System.out.println(str2);

Using C#, declare two variables of type string and assign them a value "The "use" of quotations causes difficulties." (without t

stich3 [128]

Answer:

Let the two string type variables be var1 and var2. The value stored in these two variables is : The "use" of quotations causes difficulties.

The variable which uses quoted string:

string var1 = "The \"use\" of quotations causes difficulties.";

The variable which does not use quoted string:

string var2 = "The " + '\u0022' + "use" + '\u0022' + " of quotations causes difficulties.";

Another way of assigning this value to the variable without using quoted string is to define a constant for the quotation marks:

const string quotation_mark = "\"";

string var2 = "The " + quotation_mark + "use" + quotation_mark + " of quotations causes difficulties.";

Explanation:

In order to print and view the output of the above statements WriteLine() method of the Console class can be used.

Console.WriteLine(var1);

Console.WriteLine(var2);

In the first statement escape sequence \" is used in order to print: The "use" of quotations causes difficulties. This escape sequence is used to insert two quotation marks in the string like that used in the beginning and end of the word use.

In the second statement '\u0022' is used as an alternative to the quoted string which is the Unicode character used for a quotation mark.

In the third statement a constant named quotation_mark is defined for quotation mark and is then used at each side of the use word to display it in double quotations in the output.

When you print ____, the presentation is printed with one or more slides on each piece of paper?

Artist 52 [7]

When you print handouts, the presentation is printed with one or more slides on each piece of paper. When you print handouts, it's best to have the presentation printed on them for those who can not view the presentation clearly to follow along with. This also serves as a great tool for people who missed the presentation to receive a handout later or for those there to take home and review.

Which of the following refers to semitransparent text or a faint object that appears

Agata [3.3K]

<h2>Option D: Watermark refers to semitransparent text or a faint object that appears behind the document content.</h2>

Explanation:

Footer: This is a text which appears in the bottom of every page. Mostly page numbers and the name of the publisher or the company name will be in the footer.

Page Color: This represents the color of the page

Page border: This option provides border to the page. The border can be thin or thick according to the requirement.

Watermark: This is the right answer. A watermark is added such that your content cannot be used by anyone else without permission. When you copy the text, the water mark also gets copied, thus avoiding plagiarism.
