Write a program to check the given number is binary number or not?

Description:

The binary numeral system, or base-2 number system, represents numeric values using two symbols: 0 and 1. More specifically, the usual base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers.

Code:

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 package com.govindsblog.algos;   public class MyBinaryCheck {       public boolean isBinaryNumber(int binary){                   boolean status = true;         while(true){             if(binary == 0){                 break;             } else {                 int tmp = binary%10;                 if(tmp > 1){                     status = false;                     break;                 }                 binary = binary/10;             }         }         return status;     }           public static void main(String a[]){         MyBinaryCheck mbc = new MyBinaryCheck();         System.out.println("Is 1000111 binary? :"+mbc.isBinaryNumber(1000111));         System.out.println("Is 10300111 binary? :"+mbc.isBinaryNumber(10300111));     } }

Output:

Is 1000111 binary? :true Is 10300111 binary? :false
