用java写大数，感觉就是ＢＵＧ

 import java.math.*;
 import java.io.*;
 import java.util.*;
 public class Main{
     public static void main(String[] args){
         Scanner sc = new Scanner(System.in);
         BigDecimal f1, f2;
         int c = Integer.parseInt(sc.next());
         int i = 1;
         while(sc.hasNext()){

             f1 = new BigDecimal(sc.next());
             f2 = new BigDecimal(sc.next());
             System.out.println("Case " + i + ":");
             System.out.println(f1 + " + " + f2  + " = " + f1.add(f2) );
             if(i < c)
                 System.out.println();
             //System.out.println(f1.subtract(f2));
             //System.out.println(f1.multiply(f2));
             //System.out.println(f1.divide(f2));
             i++;
             if(i > c)    break;
         }

     }
 }
