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;
        }
        
    }
}
