问题 I'm trying to detect the emoji that I get through e.g. a POST (the source ist not necessary). As an example I'm using this emoji: ✊🏾 (I hope it's visible) The code for it is U+270A U+1F3FE (I'm using http://unicode.org/emoji/charts/full-emoji-list.html for the codes) Now I converted the emoji with json_encode and I get: \u270a\ud83c\udffe Here the only part that is equal is 270a . \ud83c\udffe is not equal to U+1F3FE , not even if I add them together ( 1B83A ) How do I get from ✊🏾 to U+270A U

问题 Do you know any functions that would preform the same as ord and chr from Python in Java. Python docs on them. http://docs.python.org/2/library/functions.html#ord http://docs.python.org/2/library/functions.html#chr I've experienced manually but seem to get so many errors. This would need to work with Strings not just char . Figured I would see if there was a function to do it pre-built. Thanks 回答1: You can cast: c = (char) n; n = (int) c; 来源： https://stackoverflow.com/questions/20250048

问题 I am using Orika 1.4.5, and i want to make my BidirectionalConverter to map PaginatedResponse<T> to PaginatedResponse<S> and viceversa. The PaginatedResponse class is as follows: public class PaginatedResponse<T> { private List<T> items; private List<Sorting> orderBy; private PagingResponse paging; public PaginatedResponse(List<T> items, List<Sorting> orderBy, PagingResponse paging) { this.items = items; this.orderBy = orderBy; this.paging = paging; } // Getters } So i want that my

问题 I have a small sample of test code where I try to convert a Map into a JSON string and back. While parsing from the JSON string, the resulting map contains the String key "1" instead of the Integer key "1", thus making the test fail. The same happens with POJOs used as the key to this map. Is this behaviour expected or have I ommited some configuration for the JSON converters? public class SampleConverterTest { @Test public void testIntegerKey() { // Register an Integer converter JSON

问题 I would like to use a standard JSF converter ( javax.faces.convert.DateTimeConverter ) for a view parameter From the documentation: You can refer to the converter by class or by its ID using the component tag's converter attribute. The ID is defined in the application configuration resource file I then tried: <f:viewParam name = "rangeStartCreationDate" value = "#{doiListController.model.rangeStartCreationDate}" converter = "javax.faces.convert.DateTimeConverter" /> but I get javax.faces

问题 JodaTime is amicably the best date and time library out there, maybe. So I am tempted to receive user input from the front end xhtml Calendar widget in JodaTime instance at the backing bean. Therefore I am thinking of using JSF Converter for this job. Is this wise to do? At the same time, since I'm using Primefaces component library and I am already receiving a Date object at my backing bean, would providing a custom Converter require me to do this all over again? I.e. convert from String
