CS 1102 Unit 2 Programming Assignment: Create A New J 681577

Cs 1102 Unit 2 Programming Assignmentfirst Create A New Java Class F

Create a new Java class named "Quiz" in Eclipse within your CS1102 project. Include the main method and import javax.swing.JOptionPane. Write a program that prompts the user with a multiple-choice question using JOptionPane.showInputDialog. The question should be stored as a String with choices labeled A to E, concatenated with "+=" and "\n". Follow these steps:

  • Ask the question via a dialog box and store the response in a String variable.
  • Convert the user's answer to uppercase to handle lowercase input.
  • Implement response logic: display a message if the answer is correct ("Correct!"), a different message for incorrect valid inputs ("Incorrect. Please try again."), and another for invalid inputs ("Invalid answer. Please enter A, B, C, D, or E.").
  • Wrap the input and response logic within a while loop to repeatedly prompt until the user provides the correct answer. Use "break" or "return" to exit upon correct answer.

Test your program thoroughly with different inputs, and capture screenshots of the dialog boxes for your submission, including the question prompt, correct answer message, invalid response message, and incorrect answer response.

Paper For Above instruction

Implementing an interactive multiple-choice quiz in Java demonstrates fundamental programming concepts such as user input handling, control flow, string manipulation, and GUI components. This assignment requires creating a Java class that utilizes JOptionPane dialogs for user interaction, thereby providing a simple graphical user interface for quiz engagement.

The process begins with establishing a project environment in Eclipse, which offers an integrated development environment conducive to Java development. The creation of the "Quiz" class with a main method sets the foundation for the application. Importantly, the import javax.swing.JOptionPane; statement grants access to GUI dialog functionalities necessary for prompting questions and displaying messages.

The core functionality is to present a multiple-choice question to the user. This involves storing the question in a String variable and constructing the choices with labels from A to E. String concatenation using "+=" and newline characters "\n" enhances readability and organization of the question display. The question is then shown via JOptionPane.showInputDialog(), which presents a dialog box with the question text and accepts user input as a String.

A critical aspect is input validation and response handling. The program converts user input to uppercase using answer = answer.toUpperCase(); to ensure case insensitivity. The conditional logic employs if-else statements to determine whether the answer is correct, invalid, or incorrect but valid. Specifically, it verifies if the answer is one of the acceptable options ("A" to "E"). For correct responses, a congratulatory message appears; for invalid inputs, the program informs the user to enter valid options; and for incorrect valid answers, it prompts the user to try again.

A loop structure, such as a while(true) loop, encapsulates the question prompt and response checks, enabling repeated attempts until the correct answer is entered. When the user responds correctly, the program uses break or return to exit the loop, concluding the quiz interaction.

Thorough testing involves entering various inputs—correct answer, valid but incorrect answers, and invalid characters—to confirm appropriate responses. Capturing screenshots of the dialog boxes displaying the quiz question, correct feedback, incorrect but valid answer, and invalid input ensures documentation for submission.

This assignment provides practical experience with Java GUI components, string manipulation, conditional logic, and loop control structures, essential skills for developing interactive applications and improving user interaction proficiency.
