实力坑爹!个个让人崩溃的代码,你写过几个!
作为一个程序员,你看过哪些坑爹代码,你又写过多少坑爹代码,还有多少你不知道的坑爹代码?
给大家推荐码云上建的一个代码仓库:bullshit-codes,这个仓库了了收集很多坑爹代码,可以让别人不掉坑或者少掉坑,可以避免自己掉坑,或许哈哈一乐!
上边汇聚了各种编程语言的,仓库地址如下:

这些坑爹代码,可以让别人不掉坑或者少掉坑,可以避免自己掉坑,或许哈哈一乐。
实力坑爹 | 看看都有什么坑?
1. 你是否曾经这样使用过这样的return?
/// <summary>/// 返回值加三元运算符值/// 好像没什么不对 -_-!/// </summary>/// <param name="inputValue"></param>/// <param name="type"></param>/// <returns></returns>public static int GetValue(int inputValue, int type){return inputValue + type == 1 ? 1 : 2;}
2. 年假计算,这个程序员后应该晋升为总监了,“xxx”应该是给ceo 准备的后门。
import java.util.Scanner;public class AnnualLeaveCalculation {public int calculation(User user) {if ("xxx".equal(user.getUsername())) {return 100;} else {int year = DateUtil.daysBetween(new Date(), user.getHireDate()) / 365;if(year == ) {return 5;} else if(year > 1 && year <= 5) {return 7} else if(year > 5 && year <= 10) {return 9;} else if(year > 10) {return 10;}}}class User{/** 用户名 */private String username;/** 入职日期 */private Date hireDate;}}
3. 有没有感觉这段代码特别特别啰嗦,不够简洁
public boolean isFavorite(String articleKey, User user) {boolean isFavorite = false;if (user == null) {return false;}long userId = user.getId();Article article = getByArticleKey(articleKey);if (null == article) {return false;}List<Long> list = listAttentionUsers(article);if (list == null || list.size() <= ) {return false;}for (Long id : list) {if (id == userId) {isFavorite = true;break;}}return isFavorite;}
4. N个if,程序员的爱
import java.util.Scanner;import org.junit.Test;/***** 一个工作好几年的代码**/public class CarInfo {public CarInfoOutPut queryAllCatMonitor(Long orderId) throws ParseException {/**获取运单基本信息**/CarMonitorOutPut car = dao.getCar(orderId);CarTankRecent carTankRecent;CarInfoOutPut carInfoOutPut = new CarInfoOutPut();if(null!=car){carTankRecent =

ArrayList<TaskInformationOutPut>();List<LoadTaskInformationOutPut> queryALLTask = dao.queryALLTask(orderId);for (LoadTaskInformationOutPut loadTaskInformationOutPut : queryALLTask)

本文给大家整理了几个比较坑爹的代码,整理了几个之后,实在整理不下去了,仅供大家参考,看看能不能崩溃掉!!!
