# Check Number is Binary or Not Using Java Example

by Dinesh Thakur Category: Control Structures

Algorithm for Check Number is Binary or Not:

step 1: Set r=0,c=0

step 3: Set b=num

step 4: Repeat through step-7 while num greater than 0

step 5: If (num mod 10)equals to 0 OR equals to 1 then c=c+1

step 6: r=r+ 1

step 7: num=num/ 1 0

step 8: If c equals to r then Print it is a binary number

Else print it is not a binary number

step 9:Exit

Here is the Java Example for Check Number is Binary or Not:

```import java.util.Scanner;

public class CheckNumberisBinary

{

public static void main(String args[])

{

int r=0,c=0,num,b;

Scanner sl=new Scanner(System.in);

System.out.println("Enter a number");

num=sl.nextInt();

b= num;

while(num>0)

{

if((num %10==0)|| (num%10==1))

c++;

r++;

num=num/10;

}

if(c==r)

System.out.println(b+" is a Binary Number.");

else

System.out.println(b+" is not a Binary Number");

}

}
