Java中大整数乘法

Code:

import java.math.*;



public class BigInt {

public static void main(String[] args) {

String s1 = new String("1234567898765432100000");

String s2 = new String("1234567899999999999999");



BigInteger bigX = new BigInteger(s1);

BigInteger bigY = new BigInteger(s2);



BigInteger bigXY = bigX.multiply(bigY);

System.out.println(s1+" x "+s2+" = "+bigXY);



}

}

更详细信息应该查看java api中，java.math.BigInteger;
