我的程序老是报错怎么解决，就是输出二进制第k位的数为一时为YES
import java.util.Scanner;
public class Two {
public static void main(String[] args) {
int N,k,n1,n2=0,times=0;
Scanner scan1 = new Scanner(System.in);
Scanner scan2 = new Scanner(System.in);

N=scan1.nextInt();
k=scan2.nextInt();

n1=N;
while(n1>0&&1<=N&&N<=(Math.pow(2,23)-1)){
n2=n1%2;
n1=n1/2;

times++;
if(times==k+1)
break;

}
if(n2==1)
System.out.println("YES");
else
System.out.println("NO");
// TODO Auto-generated method stub
}
}
