算法day2---二进制找1的个数

public class deme02 {
    public static void main (String args[]){
        Scanner scanner=new Scanner(System.in);
        int N=scanner.nextInt();
        System.out.println(Integer.toString(N,2));
        int count=0;
        for(int i=0;i<32;i++){
            if((N&(1<<i))==(1<<i)){

                count++;
            }
        }
        System.out.println(count++);
    }
}

结果：
