Java Program To Multiply Two Floating Point Numbers

In this Java Program, we perform multiplication of two floating point number.

Logic : double c = double a * double b

Step 1 : Import java.util.Scanner.

Step 2 : Ask the user to enter the first number by using System.out.print method.

Step 3 : Store the user entered number in the variable num1.

Step 4 : Ask the user to enter the second number by using System.out.print method.

Step 5 : Store the user entered number in the variable num2.

Step 6 : Close the Scanner to avoid memory leak.

Step 7 : Calculate the product of the two numbers by using * operator and store the product in the variable product.

Step 8 : Display the result by using System.out.print.

Program :

import java.util.Scanner;

public class Multiply2

    {

        public static void main(String[] args)

        {

            //This reads the input provided by user using keyboard

            Scanner sc = new Scanner(System.in);

            System.out.print("Enter first number:");

            //This method reads the number provided using keyboard

            double num1 = sc.nextDouble();

            System.out.print("Enter second number:");

            double num2 = sc.nextDouble();

            //Closing Scanner after the use

            sc.close();

            //Calculating product of two numbers

            double product = num1*num2;

            //Displaying the multiplication result

            System.out.println("Output:"+product);

        }

}

Output:

Enter First Number : 1.5

Enter Second Number : 2.5

Output: 3.75
