Program: 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:
package com.java2novice.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

Exception Vs Error
An error is an irrecoverable condition occurring at runtime like out of memory error. These kind of jvm errors cannot be handled at runtime. Exceptions are because of condition failures, which can be handled easily at runtime.
Famous Quotations
Never argue with a fool, onlookers may not be able to tell the difference.
