compare

Is there anyway to check if an enum exists by comparing it to a given string? I can't seem to find any such function. I could just try to use the valueOf method and catch an exception but I'v been taught that catching runtime exceptions is not good practice. Anybody have any ideas? I don't think there's a built-in way to do it without catching exceptions. You could instead use something like this: public static MyEnum asMyEnum(String str) { for (MyEnum me : MyEnum.values()) { if (me.name().equalsIgnoreCase(str)) return me; } return null; } Edit: As Jon Skeet notes, values() works by cloning a

I have two cloned repositories of two very similar open-source projects, which I have been working on in different instances in Sublime Text 2 to arrive at my desired result. Code from both of these projects was used. I have been using Git as version control for my project, but have not included the original projects. Thus, I would like to be able to quickly compare the contents of two files of the original project and compare the differences between them and my project. I was hoping that Sublime Text 2 would have a "Compare File" feature, but I can't seem to find anything related to it in the

I’m trying to compare two dates in Android but im getting this when I write this SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyy"); String valid_until = "26052018"; final Date strDate = sdf.parse(valid_until); and if I put the try and catch like this I can’t compare the date because it says I didn't declared strDate . SimpleDateFormat is a concrete class for formatting and parsing dates in a locale-sensitive manner. It allows for formatting (date → text), parsing (text → date), and normalization. Good Approach You should use PROPER Date format. DEMO Date strDate=null; // Declare as

This question already has an answer here: Compare/Difference of two arrays in bash 7 answers This question refers to the answered question: Compare/Difference of two arrays in bash Let's take two arrays: Array1=( "key1" "key2" "key3" "key4" "key5" "key6" "key7" "key8" "key9" "key10" "key13" ) Array2=( "key1" "key2" "key3" "key4" "key5" "key6" "key11" "key12" "key13" ) Symetrical Differences between arrays: Array3=(`echo ${Array1[@]} ${Array2[@]} | tr ' ' '\n' | sort | uniq -u `) Array3 values: echo $Array3 key10 key11 key12 key7 key8 key9 Values only in Array1: echo ${Array1[@]} ${Array3[@]} |

　对拍程序（linux） 使用说明： 这里使用compare.cpp程序来对拍的，没有用bash脚本 使用时，先编译4个文件(std中放正确的标程/暴力程序 my中自己的程序 rand是用来产生数据的) g++ compare.cpp -o duipai g++ my.cpp -o my g++ rand.cpp -o rand g++ std.cpp -o std ​ 然后运行compare即可:./compare compare.cpp #include <bits/stdc++.h> using namespace std; int main(){ for(int i = 1;;i++){ system("./rand"); system("./std"); system("./my"); if(system("diff std.out my.out")){ cout<<"WA"<<endl; return 0; } else cout<<"AC"<<endl; } return 0; } 生成数据 考试（做题）时应生成&测试的5组数据 1.样例 2.2~3组手工小数据 3.边界数据 4.特例数据 5.无解数据 考试（做题）提交时的注意事项 尽量少提交，一道题目提交3次以上就没有意义了。 来源： https://www.cnblogs.com/czy--blog/p

I have a function in Python called object_from_DB . The definition isn't important except that it takes an ID value as an argument, uses the sqlite3 library to pull matching values from a table in a .db file, and then uses those values as arguments in the initialization of an object. The database is in no way changed by the use of this function. This sample code, in light of this, baffles me. >>> x = object_from_DB(422) >>> y = object_from_DB(422) >>> x == y False Why does this happen, and what sort of technique will cause x and y to return True when compared? By default, two distinct

Is it possible to compare rows for similar data in SQL Server? I have a company name column in a table where company names could be somewhat similar. Here is an example of the different 8 values that represent the same 4 companies: ANDORRA WOODS ANDORRA WOODS HEALTHCARE CENTER ABC HEALTHCARE, JOB #31181 ABC HEALTHCARE, JOB #31251 ACTION SERVICE SALES, A SUBSIDIARY OF SINGER EQUIPMENT ACTION SERVICE SALES, A SUBSIDIARY OF SINGER EQUIPMENT COMPANY APEX SYSTEMS APEX SYSTEMS, INC The way I clean it right now is using Google refine where I can identify clusters of similar data values and make them
