Question

Here is the code I am supposed to Analyze:

// If we want to use the Scanner class (type) to get user input, we need
// to import the following Java package that includes the Scanner class
// definitions. We do not have to add an import statement to use the
// print() or println() methods of the System object, because they
// are built in.

import java.util.Scanner;

public class PRG420Week1_AnalyzeAssignment {

/* The main() method you see below is special. It tells the Java interpeter to "start here."
EVERY JAVA APPLICATION OR APP MUST HAVE A MAIN METHOD CALL THAT LOOKS LIKE THIS:
public static void main(String[] args) {}
  
The "meat" of the program goes between the curly braces.
The main() method can take an array of strings (called args, which is short for "arguments").
However, in this case, we are not passing any arguments to the main() method and we are not
referencing the args variable anywhere in the body of the main() method. We are simply
telling the Java interpreter to begin running the first line within the curly braces and
keep going until the last line within the curly braces.
*/

public static void main(String[] args) {
  
// Display a message on the console using the println() method.
System.out.println("Display the line."); // Display the string "Display the line"
  
// Similar result to above--only this time, we will call the println() method with a variable.
String myStringVariable; // Declare a variable of type String called myStringVariable
myStringVariable = "Hello, world!"; // Assign string value "Hello, world!" to myStringVariable
System.out.println(myStringVariable); // Display this new string on the console
  
//Similar result to the two above--only this time, we will ask for a string from the user
//and use that string to format and display a greeting on the console.
Scanner myInputScannerInstance = new Scanner(System.in); // Create a usable instance of an input device (which for most people is a keyboard)
System.out.print("Please type a word and then press Enter: "); // Prompt user for input. print() does not add a carriage return.
// Capture first word user types in (ignore everything after the first space) and assign it to variable sentenceYouTyped
String sentenceYouTyped = myInputScannerInstance.next();
// Construct and display the message. The println() method adds a carriage return.
System.out.println("You just typed in this word: |" + sentenceYouTyped + "|");
}
  
}

Here are the questions I am being asked:

Carefully read through the code line by line, then answer the following questions in a Microsoft^® Word document:

1. What syntax signals a Java™ comment? (In other words, what symbol(s) tell the Java™ compiler not to process certain text?)
2. Type the line(s) of code that accept user input.
3. Type the line(s) of code that process user input.
4. Type the line(s) of code that produce output.
5. Type the result this program would produce if a user, when prompted, responded by typing "everyone" and then hit Enter.
6. Type the result this program would produce if a user, when prompted, responded by typing in "Mickey Mouse" and hit Enter.
7. Type the result this program would produce if a user, when prompted, responded by typing "Benjamin Franklin" and hit Enter.

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

1,Java Comment :

• // is used for single line comment
• /**/ is used for multi line comment.

2.Line of the code that accept user input :

• Scanner myInputScannerInstance = new Scanner(System.in);
• Scanner class is required when input is taken by user.

3.line(s) of code that process user input :

• String sentenceYouTyped = myInputScannerInstance.next();
• this line will read the input entered by user in the variable named sentenceYouTyped

4. the line(s) of code that produce output.:

• System.out.println("You just typed in this word: |" + sentenceYouTyped + "|");
• Above line will display user input on the console

5.Screen when user enter everyone

6.Screen when user enter Mickey Mouse

7.Screen when user enter Benjamin Franklin
