In This Assignment You Will Design And Code A Simple Java Application

In this assignment, you will design and code a simple Java application that reads in three integer values and prints out both the sum and the product of these three values. Your program output should look like the sample output provided in the "Add and Multiply Three Integers" course file resource. Complete instructions and required templates are included in the Resources section (Week X Solution Submission Template and Add and Multiply Three Integers Instructions). Your assignment will be scored on the following criteria: Design a program that meets Java arithmetic operators requirements. Code an application that exercises fundamental constructs. Test the application and document testing. Explain the approach taken to develop the application and the major decisions made. Identify relevant fundamental constructs in the submitted program. Communicates efficiently, effectively, and in an appropriate manner as an IT professional.

Paper For Above instruction

The development of a simple Java application that reads three integers, calculates their sum and product, and displays the results is an ideal exercise for students and professionals mastering fundamental programming constructs and arithmetic operations. This task not only emphasizes the importance of understanding data input, arithmetic operators, control flow, and output formatting but also encourages systematic testing and clear documentation, crucial skills in professional software development.

The first step in designing this Java program involves planning the input and output interactions. The program must prompt the user to enter three integer values, ensuring proper data validation for robust operation. Utilizing the Scanner class, a standard component in Java's utility package, facilitates reading user inputs from the console. The program then computes the sum and product using the addition (+) and multiplication (*) operators, fundamental in any programming language.

A key decision design consideration is the structure of the code, aiming for clarity and maintainability. Defining separate variables for each input and subsequent calculations helps improve code readability. Following best practices, the program should include comments explaining each major step, aiding future maintenance or enhancements.

The implementation proceeds with reading user input, performing calculations, and then outputting results formatted to match the sample provided in the course resource. Ensuring the output aligns precisely with the expected format enhances the professionalism and usability of the application.

Testing the application is crucial to confirm correctness. Inputting various sets of integers, including positive, negative, and zero values, helps verify the robustness of the program. Documenting testing procedures and results demonstrates thoroughness, a hallmark of professional programming practices.

Major decisions in the development process include choosing appropriate variable names, structuring the code logically, and adhering to Java syntax conventions. These decisions impact code clarity, ease of testing, and future scalability.

In conclusion, this Java application exemplifies core programming skills—input handling, arithmetic operations, output formatting, and testing—fundamental to building reliable software. Effective communication of the development approach and adherence to professional coding standards ensures that the program serves as a valuable learning and professional tool.
