Add And Multiply Three Integers Scoring Guide

Question

Add And Multiply Three Integers Scoring Guide Design a Java program that reads in three integer values and prints out both the sum and the product of these three values. The application is to read three integer numbers entered by the user from the keyboard, assign these to three int variables, and then output the sum and product of these values. Assume the user always enters correct information, so no input validation is needed. Use the input values 10, 20, and 30 to test the application. Your output should match a specified sample format. Create a NetBeans Java console application named U2A1_AddMultiplyThreeInts, develop the program according to these requirements, and test it with the given inputs. Document your testing results with a screenshot in a single document. Explain your approach, including the fundamental Java constructs used that are relevant to your program, and discuss major decisions made during development.

Introduction The task of designing a simple Java application to add and multiply three integers encompasses understanding key programming constructs such as input/output operations, variable assignment, and basic arithmetic calculations. Executing this task successfully demonstrates foundational programming skills in Java, including use of the Scanner class, variable management, and output formatting. Development Approach The development process began by creating a new console application in NetBeans named U2A1_AddMultiplyThreeInts. The core of the application involves reading three integers from the user, storing these in three separate variables, and then computing their sum and product. Given the assumption of correct input data, input validation was unnecessary, simplifying the implementation. The application uses the Scanner class to read user inputs from the console. Each input is assigned to a separate integer variable to facilitate clarity and ease of computation. As per the assignment instructions, the program outputs the sum and product in a formatted manner that mirrors the sample output, enhancing readability and adherence to specifications. Implementation Details Code begins with importing relevant classes, primarily java.util.Scanner. The main method initializes a Scanner object to capture user input. The program prompts the user to enter three integers consecutively. These inputs are then stored in variables num1, num2, and num3. Next, the program calculates the sum by adding the three variables and computes the product by multiplying them. It then displays the results in the following format: Sum is: [sum] Product is: [product] This output aligns with the example provided in the assignment description, ensuring clarity. Testing & Evaluation Using the supplied test data of 10, 20, and 30, the application was run, and the output was verified against expected results. The output confirmed that the calculations were correct, as the sum was 60 and the
