java从键盘输入任意一组数据存入数组中统计非负数个数及非负数个数

import java.util.Scanner;

public class ww{

public static void main(String [] args){

int n;

int num=0;

int sum=0;

System.out.println("请输入一个数：")；

Scanner sc=new Scanner(System.in);

n=sc.nextInt();

System.out.println("请输入一组数：")

int [] a=new int [n];

for(int i=0;i

a[i]=sc.nextInt();

}

System.out.println("非负数：")

for(int i=0;i

if(a[i]>=0){

System.out.println(a[i]);

num++;

sum+=a[i];

}

}

System.out.println("非负数个数："+num);

System.out.println("非负数总和："+sum);

}

}
