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;

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!!!
