CS 1102 Unit 1 Programming Assignment Because This Is The Fi

Cs 1102 Unit 1 Programming Assignment Because This Is The First

Because this is the first programming assignment in the course, the instructions are more detailed than in later units. You will need to follow the instructions carefully. First, download and install Eclipse IDE for Java Developers. Once Eclipse is installed, open the application and select a workspace location when prompted. Click "Use this as the default and do not ask again" and then "OK".

In Eclipse, create a new Java project named "CS1102" by selecting "File" -> "New" -> "Java Project" and entering "CS1102" as the project name, then clicking "Finish".

Next, create a new Java class named "SuperPower" by choosing "File" -> "New" -> "Class", entering "SuperPower" as the class name, and clicking "Finish".

Within the "SuperPower.java" file, add a "main" method which will be executed as the program. Inside the class, add the following code inside the "main" method:

import javax.swing.JOptionPane;

public static void main(String[] args) {


String power = JOptionPane.showInputDialog("What is your super power?");


power = power.toUpperCase();


JOptionPane.showMessageDialog(null, power + " TO THE RESCUE!");


}

This program first prompts the user to input a superpower via a dialog box. It then converts the input to uppercase using "toUpperCase" and displays a message dialog expressing that the superpower is "to the rescue".

To make the program more interactive, run the code: the input dialog will ask for your superpower, and the message dialog will display your input in uppercase with the phrase "TO THE RESCUE!".

For additional features, take screenshots of the input dialog (with lowercase input) and the message dialog (with uppercase output) for submission. The required files for submission are "SuperPower.java" and the two screenshots.

Paper For Above instruction

The fundamental goal of this programming assignment is to introduce students to the Java programming language and the Eclipse Integrated Development Environment (IDE) through a practical, hands-on project. The task involves creating a simple interactive Java application that utilizes graphical user interface (GUI) components, specifically dialog boxes, to communicate with the user.

Initially, students are guided to install the Eclipse IDE, a widely used development environment for Java programming due to its robustness and extensive features. Setting up the IDE, creating a project named "CS1102," and establishing a Java class called "SuperPower" serve as foundational steps to familiarize students with the workspace and file management in Java development. These preliminary steps are essential for organizing code and understanding the workflow involved in Java programming.

Once the class skeleton has been set up, students are instructed to write a main method—a mandatory entry point for Java applications. The initial code within the main method involves prompting the user to input their superpower using "JOptionPane.showInputDialog," a method from the javax.swing package that simplifies obtaining user input through a dialog box. This step introduces core programming concepts such as variable declaration, data types, and string input handling.

Processing the input involves converting the user's input to uppercase via the "toUpperCase" method. This conversion emphasizes string manipulation techniques, demonstrating how Java can modify user input for specific purposes. The use of string methods like "toUpperCase" deepens students' understanding of object-oriented string handling in Java, where strings are objects with associated methods.

Finally, the application displays a congratulatory message that incorporates the user's input in uppercase, appended with the phrase "TO THE RESCUE!". This step introduces GUI output via "JOptionPane.showMessageDialog," reinforcing the application's interactive capabilities. The visual nature of dialog boxes as opposed to console output enhances user experience and aligns with real-world GUI application development.

Throughout the project, students learn important concepts including event-driven programming, dialog-based user interactions, string manipulation, and IDE features such as code auto-completion and error diagnostics. They are also encouraged to test their code by entering lowercase input to verify the "toUpperCase" conversion works correctly, which cultivates debugging and testing skills integral to software development.

Moreover, the assignment emphasizes best practices such as using appropriate imports, commenting code for clarity, and organizing code logically. The requirement to take screenshots of the dialogs serves as a practical exercise in documenting work and grasping user interface behavior. These skills collectively prepare students for more sophisticated Java programming tasks and GUI development in future coursework.

In conclusion, this assignment provides a comprehensive introduction to Java programming fundamentals, IDE utilization, and GUI interaction, forming a solid basis for subsequent programming challenges. It encourages critical thinking, problem-solving, and familiarity with Java's string manipulation and dialog-based interactions—key skills for any aspiring software developer.
