Develop Your First Object-Oriented Program For A Computer Cl

Develop Your First Object Oriented Program for a Computer Class

This assignment is to develop your first object-oriented program. You will create a class named Computer with at least two attributes: one integer data type and one String data type. The class must include at least one method. Additionally, prepare a class diagram and source code for the Computer class. Then, write a program that creates two instances of the Computer class—one representing an existing computer and another representing a future, more desirable computer. The program should prompt the user for information about both computers, calculate the difference between their integer attributes (e.g., memory), and display all relevant information along with the improvement. The project includes pseudocode and a design document, and requires well-commented Java source files.

Paper For Above instruction

The purpose of this assignment is to introduce students to fundamental object-oriented programming concepts using Java. By designing a simple class and implementing a program that utilizes multiple class instances, students will gain practical experience in class creation, encapsulation, user input handling, and basic calculations within a programming context. This foundational exercise prepares students for more complex object-oriented programming tasks by emphasizing the importance of structured code, documentation, and user interaction.

The first step in this project involves defining a Java class named Computer. This class should have at least two attributes: one integer, such as memory, and one String, perhaps brand. The class must also include at least one method, such as a getter or a setter, to demonstrate behavior beyond just storing data. Creating a class diagram that visually represents these attributes and methods will help in understanding the structure. The class diagram should be a simple UML representation, which can be prepared using diagramming tools and included in the documentation.

Once the class structure is designed, students will write the Java source code for this class and save it as Computer.java. This code must be well-commented to explain the purpose of attributes and methods, aligning with best coding practices. The next step involves developing a main program that creates instances of the Computer class—one to simulate the student’s current computer and another representing their ideal future computer. The program will employ the Scanner class to gather user input about each computer’s specifications.

The program's core functionality revolves around prompting the user for details about both computers, specifically focusing on an integer attribute like memory. After capturing the information, the program calculates the difference in this attribute—indicating the level of improvement. For example, if the existing computer has 8GB of memory and the future computer has 16GB, the program will compute and display a 8GB increase. This calculation helps illustrate how object-oriented programming facilitates modeling real-world objects and their comparisons.

To make the program comprehensive, it should display all entered data along with the calculated improvement. The output should be formatted clearly, providing insight into both the current and future computer specifications. Proper commenting within the code is essential to enhance code readability and maintainability.

The planning phase requires students to create pseudocode—a step-by-step, language-agnostic plan of how the program will execute. This pseudocode should include input prompts, data storage, calculation steps, and output presentation. Including this pseudocode in the design document is crucial, as it guides the coding process and ensures logical flow.

Finally, students are required to submit their design document, including the class diagram and pseudocode, along with the Java source files. Submission should also include the .class files resulting from compilation to demonstrate the program's operability. This comprehensive approach ensures students understand both the conceptual and practical aspects of object-oriented programming in Java.
