write an algorithm, pseudo code and program code that reads two numbers and multiplies them together and print out their product

Answer 1

// importing Scanner library to read in user input

import java.util.Scanner;

public static void multiply() {

// surrounding code with try/catch, to catch possible errors thrown when reading in user input

try {

Scanner input = new Scanner(System.in);

// reading in doubles because the double type allow for integers and floats.

System.out.println("Please enter your first number: ");

double a = input.nextDouble();

System.out.println("Please enter your second number: ");

double b = input.nextDouble();

double product = a * b;

System.out.println("The product of your two numbers is "+ product);

}

catch (Exception e) {

System.err.println(e.getMessage());

}

}
