A+B and A*B problem 大数相加 相乘 模拟 题意 给你两个数a和b,这两个数很大,然后输出这两个数相加的和,相乘的积. 解题思路 模拟,但是还是搜了搜代码实现,发现这个大佬写的是真的简洁高效. 下面第一个代码转自博客(修改了一些) >>>https://blog.csdn.net/hacker00011000/article/details/51298294 第二个代码是CZH同学的代码,代码更是简单易懂! 别的一些思路 大数相加相乘 https://blog.csdn…

问题: 大数相加不能直接使用基本的int类型,因为int可以表示的整数有限,不能满足大数的要求.可以使用字符串来表示大数,模拟大数相加的过程. 思路: 1.反转两个字符串,便于从低位到高位相加和最高位的进位导致和的位数增加: 2.对齐两个字符串,即短字符串的高位用‘0’补齐,便于后面的相加: 3.把两个正整数相加,一位一位的加并加上进位. 具体代码如下: /** * 用字符串模拟两个大数相加 * @param n1 加数1 * @param n2 加数2 * @return 相加结果 */ pu…

随机生成10个数,填充一个数组,然后用消息框显示数组内容,接着计算数组元素的和,将结果也显示在消息框中 一,      设计思路: 先生成随机数数组,再将数组保存在一个字符串中,然后将数组各数字加和, 二,      程序流程图     三,      源程序代码 import javax.swing.JOptionPane; public class ArraySum { public static void main(String[] args) { int[] array=new int[…

题目要求:用字符串模拟两个大数相加. 一.使用BigInteger类.BigDecimal类 public static void main(String[] args) { String a="8888899999999888";  String b="88888888888888";  String str=new BigInteger(a).add(new BigInteger(b)).toString();  System.out.println(str);…
