We do following

public static int BinaryGap(int n)
{
	int maxGap = 0;
	int currentGap = 0;
	while(n > 0)
	{
		if(n % 2 == 0)
		{
			currentGap++;
			if(maxGap < currentGap)
			{
				maxGap = currentGap;
			}
		}
		else if(n % 2 == 1)
		{
			currentGap = 0;
		}
		n = n/2;
	}
	return maxGap;
}

In a loop, divide the number by 2. Keep count of the number of times, n%2==0 is found continuously

public int maxGap(int n){
	if(n<0){ return -1;}
	int maxgap = 0;
	int gap=0;
	while(n>0){
		if(n%2==0){
			gap++;
			if(gap>maxgap){ maxgap = gap; }
		} else {
			gap=0;
		}
	}
}
