尝试一下java 的大数类

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

public class Main {
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		while(in.hasNextBigInteger())
		{
			BigInteger a = in.nextBigInteger(), b = in.nextBigInteger();
		    BigInteger c = a.multiply(b);
		    System.out.println(c);
		}
	}
}
