Check Number is Binary or Not Using Java Example

Algorithm for Check Number is Binary or Not:

step 1: Set r=0,c=0

step 2: Read num

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"); 
            } 
 }
