HDU 1047 Integer Inquiry JAVA大数

第一次写JAVA  纪念一下～

import java.io.*;
import java.math.BigInteger;
import java.util.*;

public class Main {
	public static void main(String[] args) {
			Scanner cin = new Scanner(System.in);
			int T = cin.nextInt();
			BigInteger a, ans;
			for(int i = 0; i < T; i++){
				ans = BigInteger.ZERO;
				while(cin.hasNext()){
					a = cin.nextBigInteger();
					if(a.equals(BigInteger.ZERO)) break;
					ans = ans.add(a);
				}
				if(i != 0) System.out.println();	
				System.out.println(ans);
			}
		}
}
