主要是格式问题

import java.util.Scanner;public class Main{    public static void main(String[] args) {        Scanner input = new Scanner(System.in);        int sum = 0;        int m = input.nextInt();        while (m-->0) {            int n = input.nextInt();            for (int i = 0; i < n; i++) {                int a = input.nextInt();                sum += a;            }            System.out.println(sum);            sum = 0;            if (m!=0) {                System.out.println();            }        }    }}
