Multiplication of two numbers in JAVA

In the previous blog we saw subtraction of two numbers. Now, we will see about datatypes and multiplication of two numbers .

Basic Data Type:- int, char, float, double

int Datatype:-Its an integer datatype .Its of 4 bytes .Its range is -2,147,483,648 to 2,147,483,647.

char Datatype:-Its an character datatype. Its of  2 bytes. 

float Datatype:-Its for floating point numbers. Its of  4 bytes.

double Datatype:-Its for large floating point numbers .Its of 8 bytes.

1.Multiplication of two numbers using int datatype 

import java.io.*;

import java.util.*;

public class multiplication{

    public static void main (String [] args)

    {

        int number1,number2,number3;

        System.out.println("Enter two numbers:");

        Scanner sc =new Scanner(System.in);

        number1=sc.nextInt();

        number2=sc.nextInt();

        number3=number1*number2;

        System.out.print("Multiplication of two number is "+number3);

    }

}

Algorithm:-

1.Start 

2.Import the packages respectively.

3.Declare the variables number1 and number 2  by using the datatype int .Use the print statement and display a message "Enter two numbers:"

4.By using the scanner class get the input  by using System.in and create the object sc 

5.Get the first & second number by using scanner class .

6.By using number3 variable multiply the two numbers number1 & number2 

7. The print statement gets displayed in the next line to  display a message "Multiplication   of two numbers" along with the Multiplication  of two numbers .

8.Stop.

2.Multiplication of two numbers using float datatype 

import java.io.*;

import java.util.*;

public class multiplication{

    public static void main (String [] args)

    {

        float number1,number2,number3;

        System.out.println("Enter two numbers:");

        Scanner sc =new Scanner(System.in);

        number1=sc.nextFloat();

        number2=sc.nextFloat();

        number3=number1*number2;

        System.out.print("Multiplication  of two number is "+number3);

    }

}

Algorithm:-

1.Start 

2.Import the packages respectively.

3.Declare the variables number1 and number 2  by using the datatype float .Use the print statement and display a message "Enter two numbers:"

4.By using the scanner class get the input  by using System.in and create the object sc .

5.Get the first & second number by using scanner class .

6.By using number3 variable multiply the two numbers number1 & number2 

7. The print statement gets displayed in the next line to  display a message "Multiplication  of two numbers" along with the Multiplication  of two numbers .

3.Multiplication of two numbers using double datatype 

import java.io.*;

import java.util.*;

public class multiplication{

    public static void main (String [] args)

    {

        double number1,number2,number3;

        System.out.println("Enter two numbers:");

        Scanner sc =new Scanner(System.in);

        number1=sc.nextDouble();

        number2=sc.nextDouble();

        number3=number1*number2;

        System.out.print("Multiplication of two number is "+number3);

    }

}
