Java program to print two multiply binary numbers with a solution. A binary number is a number expressed in the base-2 numeral system, also known as the binary numeral system, in digital electronics and mathematics.

import java.util.Scanner;

public class Main {

public static void main(String[] args)

{

long bin1, bin2, multiply = 0;

int digit, factor = 1;

Scanner in = new Scanner(System.in);

System.out.print("first bin number");

bin1 = in.nextLong();

System.out.print("second bin number");

bin2 = in.nextLong();

while (bin2 != 0)

{

digit = (int)(bin2 % 10);

if (digit == 1)

{

bin1 = bin1 * factor;

multiply = binproduct((int) bin1, (int) multiply);

}

else

{

bin1 = bin1 * factor;

}

bin2 = bin2 / 10;

factor = 10;

}

System.out.print("Product of two bin numbers: " + multiply+"\n");

}

static int binproduct(int bin1, int bin2)

{

int i = 0, remainder = 0;

int[] sum = new int[20];

int bin_prod_result = 0;

while (bin1 != 0 || bin2 != 0)

{

sum[i++] = (bin1 % 10 + bin2 % 10 + remainder) % 2;

remainder = (bin1 % 10 + bin2 % 10 + remainder) / 2;

bin1 = bin1 / 10;

bin2 = bin2 / 10;

}

if (remainder != 0)

{

sum[i++] = remainder;

}

--i;

while (i >= 0)

{

bin_prod_result = bin_prod_result * 10 + sum[i--];

}

return bin_prod_result;

}

}

Output:

First binary number: 110

Second binary number: 101

Product of two binary numbers: 11110

## What is binary number in java program

A binary number is made up of two digits: 0s and 1s. Binary numbers have a base of 2 and are represented as such. (101)2 ( 101 ) 2 is an example. A bit is a name given to each digit in a binary integer.

## What is long keyword in java programming

A minimum value of -263 and a maximum value of 263-1 can be found in the long. Long can now be represented as an unsigned 64-bit long with a minimum value of 0 and a maximum value of 264-1 in Java 8. 0L is the default value. It has an 8-byte default size. It’s utilized when you need an integer value with a larger range.
