# Java program to print two multiply binary numbers with solution

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;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.
