Ex : Each of the following questions is about event processing. Mark T if the question is valid, otherwise F.
(1) Subclasses of EventObject on components handle special types of events such as action, window, component, mouse, and key events ( )
(2) Source objects activate events, event-related objects handle events, and event-related objects are called risers ( )
(3) For all event types, the riser interface is usually named XListener for Xevent (except for MouseMotionListener) ( )
(4) e.getSource() may be used to determine if the source object is a button, check box, or radio button ( )
(5) Since the riser class is not shared by other applications, it is appropriate to be defined inside the frame as an internal class ( )
(6) Since all methods within the riser interface are abstract and require implementation of all methods, classes called adapters are provided for convenience ( )

Please solve the problem. and Please Let me explain the process.

Thank you:)

For this assignment, create a complete UML class diagram of this program. You can use Lucidchart or another diagramming tool. If you can’t find a diagramming tool, you can hand draw the diagram but make sure it is legible.

Points to remember:

• Include all classes on your diagram. There are nine of them.

• Include all the properties and methods on your diagram.

• Include the access modifiers on the diagram. + for public, - for private, ~ for internal, # for protected

• Include the proper association lines connecting the classes that “know about” each other.

o Associations

o Dependencies

o Inheritance

o Aggregation

o Composition

• Static classes are designated on the diagram with > above the class name, and abstract classes are designated with > above the class name.

How do I write this method correctly? What Ihave is a Java project assignment where I'm supposed to create a Roshambo game. One of the classes that the project is supposed to have is a class called "RoshamboApp that let the user play 1 of 2 AI opponents, a "Bart" class, and a "Lisa" class. The instructions say "Create a class names RoshamboApp that allows player1 to play Bart or Lisa as shown in the console output. Rock should beat scissors, paper should beat rock, and scissors should beat paper." The code for a switch statement that I wrote is below, but the IDE says the way I wrote it is wrong. How can I write it correctly?

The assignment:

Project 10-3: Roshambo

Create an application that uses an enumeration and an abstract class.

Console

Welcome to the game of Roshambo

Enter your name: Joel

Would you like to play Bart or Lisa? (B/L): b

Rock, paper, or scissors? (R/P/S): r

Joel: rock

Bart: rock

Draw!

Play again? (y/n): y

Rock, paper, or scissors? (R/P/S): p

Joel: paper

Bart: rock

Joel wins!

Play again? (y/n): y

Rock, paper, or scissors? (R/P/S): s

Joel: scissors

Bart: rock

Bart wins!

Play again? (y/n): n

Specifications

• Create an enumeration named Roshambo that stores three values: rock, paper, and scissors. This enumeration should include a toString() method that can convert the selected value to a string.
• Create an abstract class named Player that stores a name and a Roshambo value. This class should include an abstract method named generateRoshambo() that allows an inheriting class to generate and return a Roshambo value. It should also include get and set methods for the name and Roshambo value.
• Create classes named Bart and Lisa that inherit the Player class and implement the generateRoshambo() method. The Bart class should always select rock. The Lisa class should randomly select rock, paper, or scissors (a 1 in 3 chance of each).
• Create a class named Player1 that represents the player who will play Bart or Lisa. This class should inherit the Player class and implement the generateRoshambo() method. This method can return any value you choose. (You must implement this method even though it isn’t used for this player).
• Create a class named RoshamboApp that allows player 1 to play Bart or Lisa as shown in the console output. Rock should beat scissors, paper should beat rock, and scissors should beat paper.
• Use an enhanced version of the Console class to get and validate the user’s entries.

My code so far for the class in question:

// R = rock
// P = paper
// S = scissors

import java.util.Scanner;

public class RoshamboApp {

String R;
String P;
String S;   
String UserChoice;  
String AIChoice;

switch(UserChoice)
{
    case R:
        if (AIChoice == P) System.out.println("you lose.");
        if (AIChoice == S) System.out.println("you win!");
    case P:
        if (AIChoice == R) System.out.println("you win!");
        if (AIChoice == S) System.out.println("you lose.");
    case S:
        if (AIChoice == R) System.out.println("you lose.");
        if (AIChoice == P) System.out.println("you win!");      
}
if (UserChoice == AIChoice) System.out.println("it's a draw.");

}

This assignment will be assessed using additional criteria provided here.

Your report must include a reference list. All research should be cited in the body of the paper. In-text citations and corresponding references should be included in your paper. For more information on APA style, please visit the APA lab. The paper should be written in third person, which means that pronouns like “I,” “we,” and “you” are not appropriate. The use of direct quotes is strongly discouraged.

Your assignment should contain a cover page, an abstract page, and a reference page in addition to the body. The body of the paper should be 3–4 pages in length, starting with a brief 1-paragraph introduction and ending with a short conclusion. The entire submission will be 6–8 pages in length.

Please submit your assignment as a Word document in APA format using the attached template.

Submitting your assignment in APA format means that you will need a minimum of the following:

Title page: Remember to include the running head and the title in all capital letters.

Abstract: This should be a summary of your paper, not an introduction. Begin writing in third person voice.

Body: The body of your paper begins on the page following the title page and abstract page, and it must be double-spaced (be careful not to triple- or quadruple-space between paragraphs). The typeface should be 12-point Times New Roman or 12-point Courier in regular black type. Do not use color, bold type, or italics, except as required for APA headings and references. The deliverable length of the body of your paper for this assignment is 3–4 pages. In-body academic citations to support your decisions and analysis are required. A variety of academic sources is encouraged.

Reference page: References that align with your in-text academic sources are listed on the final page of your paper. The references must be in APA format, using appropriate spacing, hang indention, italics, and upper and lower case as appropriate for the type of resource used. Remember, the reference page is not a bibliography, but it is a further listing of the abbreviated in-text citations that are used in the paper. Every referenced item must have a corresponding in-text citation.

PumpkinPlus is a profit-maximizing firm that produces a carving tool using labor and materials according to a production function for which both labor and materials are normal inputs. PumpkinPlus faces a downward-sloping demand curve for carving tools. Say the wage rate rises. What changes do you predict in the use of labor, the use of materials, the number of tools produced, the price per carving tool, and the profit earned by the firm in the long run? Explain your reasoning and mention why you may not be able to predict the direction of certain changes. Provide a sketch of an isoquant/isocost line diagram and a diagram showing demand, marginal revenue, average total cost, and marginal cost to illustrate the old and new amounts of each variable listed.

Psychologists like B. F. Skinner have studied how we can use operant conditioning to change the behavior of people and animals. Drawing on your personal experience, choose a person or animal whose behavior you want to change. (You may select your own behavior for this question if you wish.)
