Multiplying in java: Enhancing programming skills is very important no matter what language you have chosen. So, practice frequently with these simple java programs examples and excel in coding the complex logic.

Program to Multiply Two Floating Point Numbers

How to multiply floating point numbers: We can find the product of two floating point numbers easily in Java.

Let’s see 2 different methods to do it.

Method-1 : Multiplication using the ‘*’ operator

We can find the product easily by simply using the ‘*’ operator. It takes two operands and multiplies them.

Below program is implementation code.

import java.util.Scanner;
class multiply
{
    public static void main(String args[])
    {
        System.out.println("Enter two floating-point numbers");
        //Scanner class to take input
        Scanner scan = new Scanner(System.in);
        float num1 = scan.nextFloat(), num2 = scan.nextFloat();
        //Multiplying both the operands to find the product
        float product = num1 * num2;
        //Printing the result
        System.out.println("The product of "+num1+" and "+num2+" is "+product);
    }
}

Output:

Enter two numbers
15.3
63.1
The product of 15.3 and 63.1 is 965.43

Method-2 : Multiplication using a user defined method

We can multiply two floating point numbers using a user defined method.

The process is completely same, here we only create a user defined method and we will put the same logic inside the user defined method. We need to call the method to get the result.

Below program is implementation code.

import java.util.Scanner;
class multiply
{
    public static float prod(float num1, float num2)
    {
        //This user defined function takes two numbers as input and returns the product
        float product = num1*num2;
        return product;
    }
    public static void main(String args[])
    {
        //static initialization (f is used to signify the compiler that it is a floating
        //point number and not double)
        float num1 = 15.3f, num2 = 63.1f;

        //Calling the user defined function prod() and passing num1 and num2 into it
        //then printing the result
        System.out.println("The product of "+num1+" and "+num2+" is "+prod(num1,num2));
    }
}

Output:

The product of 15.3 and 63.1 is 965.43
