HDU 1002 大整数

哈哈。。。几年一下自己手写的第一个Java大整数程序：

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

public class Main {
	public static void main(String agrs[]){
		Scanner cin = new Scanner(System.in);
		while (cin.hasNextInt()){
			int n = cin.nextInt();
			for (int i = 1; i <= n; ++i){
				BigInteger a = cin.nextBigInteger();
				BigInteger b = cin.nextBigInteger();
				BigInteger c = a.add(b);
				System.out.println("Case " + i + ":");
				System.out.println(a + " + " + b + " = " + c);
				if (i != n) System.out.println();
			}
		}
	}

}
