In this core java programming tutorial we will write a program to Find number is binary or not in java.
What is binary number?
Binary number consists of only 0 & 1.
Example>
11001011 is binary number.
10000112 is not binary number. (because it consists of 2)

public class BinaryNumberOrNotExample {
public static void main(String a[]){
int n=11001011;
System.out.println(isBinaryNumber(n)? n+" is binary number." : n+" is not binary number.");
n=11001110;
System.out.println(isBinaryNumber(n)? n+" is binary number." : n+" is not binary number.");
n=10000112;
System.out.println(isBinaryNumber(n)? n+" is binary number." : n+" is not binary number.");
n=11005110;
System.out.println(isBinaryNumber(n)? n+" is binary number." : n+" is not binary number.");
}
/**
* returns true if number is binary.
*/
public static boolean isBinaryNumber(int n){
while(n != 0){
if(n%10 > 1){
return false; //number containing any digit greater than 1 means its not binary.
}
n = n/10;
}
return true;
}
}
/*OUTPUT
11001011 is binary number.
11001110 is binary number.
10000112 is not binary number.
11005110 is not binary number.
