JAVA大数运算--加减乘除取余

JAVA大数加减乘除超级简单五个运算五行代码即可

import java.math.BigInteger;

public class 大数运算 {
    
    
    public static void main(String[] args) {
    
    
        String num1 = "999999999999999999999999999999";
        String num2 = "888888888888888888888888888888";
        BigInteger big1 = new BigInteger(num1);
        BigInteger big2 = new BigInteger(num2);
        System.out.println("加法操作:" + big1.add(big2));
        System.out.println("减法操作:" + big1.subtract(big2));
        System.out.println("乘法操作:" + big1.multiply(big2));
        BigInteger result[] = big1.divideAndRemainder(big2);
        System.out.println("相除后的商是:" + result[0]);
        System.out.println("相除后的余数是:" + result[1]);
    }
}

运算结果如图
