Java에서 키보드로 배열을 입력하는 방법

public class exchangeNum {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
            String str=scanner.nextLine();
            String[] Arrays=str.split(",");   //通过“，”分离
            int[] a=new int[Arrays.length];
            for(int i=0;i<a.length;i++){
                a[i]=Integer.parseInt(Arrays[i]);   //将String型转化成int型
                System.out.print(a[i]+" ");
                }
        }
    }
