Question

Please create a Java Program, Using Netbeans JDK, that Asks the operator for 2 numbers, and the user's First and Last Name, and calculates the sum, difference, quotient, and product of the 2 numbers. The program should display to screen:

"Hello ";{First Name Last Name}
"The Sum is ": {Sum}
"The Difference is ": {Difference}
"The Product is: ": {Product}
"The Quotient is ": {Quotient}

Each student should post a Java program should have: (a) Pseudocode and (b) adjacent Java code. (*Note: Pseudocode must be placed in comments)

//Pseudocode

Java Code

//Pseudocode2

Java Code 2

Thanks for the question.

Here is the completed code for this problem. Comments are included so that you understand whats going on. Let me know if you have any doubts or if you need anything to change.

Thank You !!

import java.util.Scanner;

public class FE1 {

    // create a Scanner object to take user inputs
    private static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {

        // takes all 4 input from user
        System.out.print("Enter first name: "); // print message to user for entering first name
        String firstName = scanner.nextLine();
        System.out.print("Enter last name: "); // print message to user for entering last name
        String lastName = scanner.nextLine();
        System.out.print("Enter first number: "); // print message to user for entering first number
        double firstNumber = scanner.nextDouble(); // storing the number as double
        System.out.print("Enter second number: "); // print message to user for entering second number
        double secondNumber = scanner.nextDouble(); // storing the number as double

        // print the results
        System.out.println("Hello: " + firstName + " " + lastName);
        System.out.println("The Sum is: " + (firstNumber + secondNumber)); // sum the two numbers
        System.out.println("The Difference is: " + Math.abs(firstNumber - secondNumber)); // difference the two numbers
        System.out.println("The Product is: " + (firstNumber * secondNumber)); //// multiply the two numbers
        if (secondNumber != 0) // check if the denominator is not zero
            System.out.println("The Quotient is: " + (firstNumber / secondNumber));
        else // if denominator is zero print message
            System.out.println("The Quotient is: undefined");

    }

}
