问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . I've looked at both Liquibase and Flyway individually and on an individual comparison alone, Liquibase seems like the better tool for our needs. Some sources mention using both Liquibase and Flyway together. Liquibase seems to have everything Flyway has and more flexibility when it

问题 I need to comapre two files f1.txt and f2.txt and obtain matches, and non-matches, for this case I am looking to match first field on both files. And print first the second field of f2.txt, then print the entire line of f1.txt. And for no match found on f2.txt to state "Not Found" and then print f1.txt entire line. F1.txt 1;2;3;4;5;6;7;8 1a;2;3;4;5;6;7;8 1b;2;3;4;5;6;7;8 2b;2;3;4;5;6;7;8 F2.txt 1;First 1a;Firsta 1b;Firstb Desired output: First;1;1;2;3;4;5;6;7;8 Firsta;1a;1a;2;3;4;5;6;7;8

问题 can i somehow compare two numbers in regex? i want regex that is correct for 10-12, but incorrect for 12-10. I mean that 10 must be smaller than 12. I want to do it in Javascript. 回答1: If the input is always of the form X-Y, then why not use the split() function with '-' as the delimiter and then compare the two parts with > You can't compare numerical values using RegExps. 回答2: I wouldn't use regex for this. I'd split the string on the operator, then compare the two resulting numbers based

问题 Happens if at least one of the values (values == value in RowFilter, value in entry) is a decimal. Here's a failing test: @Test public void testRowFilterNumberMixCore() { TestEntry entry = new TestEntry(1.2f); RowFilter filter = RowFilter.numberFilter(ComparisonType.AFTER, 1, 0); assertTrue(entry + "must be included " + filter, filter.include(entry)); } The output is: junit.framework.AssertionFailedError: [entry: 1.2] must be included [RowFilter: ComparisonType = AFTER, comparableValue: 1,

问题 I have a hashmap with byte[] keys. I'd like to sort it through a TreeMap. What is the most effective way to implement the comparator for lexicographic order? 回答1: Using Guava, you can use either of: UnsignedBytes.lexicographicalComparator() SignedBytes.lexicographicalComparator() The UnsignedBytes comparator appears to have an optimized form using Unsafe that it uses if it can. Comments in the code indicate that it may be at least twice as fast as a normal Java implementation. 回答2: Found this

问题 I know that there has been a lot of questions like this but I couldn't find a reply that would satisfy my needs. I have to write an application that will compare XML files: there will be 2 types of compare, first for 2 files, listing all the differences and second one for multiple XML files listing all the variations from averages. I am looking for some kind of class, library or API that will help me finish this task. Can you suggest some solutions ? And yet, I do not know if I should use DOM

问题 I wanted to compare a string without actually defining one of them as a string, something like this, if (string == 'add') Do I have to declare 'add' as a string or is it possible to compare in a similar way? 回答1: In C++ the std::string class implements the comparison operators, so you can perform the comparison using == just as you would expect: if (string == "add") { ... } When used properly, operator overloading is an excellent C++ feature. 回答2: You need to use strcmp . if (strcmp(string,
