simpledateformat

问题 I'm developing an android application and am attempting to integrate the Bluemix service - Personality Insights. However, due to a conflict with dates (Bluemix service is assuming a Java SimpleDateFormat which includes the symbol 'X', while Android's SimpleDateFormat does not include this symbol) causing an error (Log below). My question is this, is there a way to brute force the app to use the Java SimpleDateFormat version as opposed the Android version? other than that I don't see how I can

问题 Why getHours() for "09:50" return 8? Code: SimpleDateFormat sdf = new SimpleDateFormat("HH:mm"); Date date = sdf.parse("09:50"); int hours = date.getHours(); // return 8 instead of 9 ??? 回答1: Calendar prueba = Calendar.getInstance(); prueba.set(2013, 1, 6, 10, 49, 32); int day = prueba.get(Calendar.DAY_OF_MONTH); int month = prueba.get(Calendar.MONTH); int year = prueba.get(Calendar.YEAR); int hours = prueba.get(Calendar.HOUR); int minutes = prueba.get(Calendar.MINUTE); int seconds = prueba

问题 String str = "13/06/2011"; SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); Date date = (Date)formatter.parse(str); 回答1: I guess that your Date class is actually a java.sql.Date . 回答2: What does your import statement say? Are you importing some other class (for example java.sql.Date ) by accident? What does the compiler say when you remove the class cast (which should not be there)? 回答3: DateFormat.parse() returns an instance of java.util.Date and not java.sql.Date . In order

问题 Decided to ask this, as I couldn't find a similar example in StackOverflow. I want to parse a date string and its timezone using SimpleDateFormat. I (hope) I read the documentation carefully, and wrote this program that replicates the issue. import java.text.DateFormat; import java.util.Date; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Locale; public class SDF { private static final String FORMAT = "EEE, d MMM yyyy HH:mm:ss Z"; public static void main

问题 I am trying to change the format of a date but cannot get it to work from Nov 18, 2014 to 2014-11-18 String s="Nov 18, 2014" s= new SimpleDateFormat("yyyy-MM-dd").format(new SimpleDateFormat("LLL dd, yyyy").parse(s)); something is wrong with this part new SimpleDateFormat("LLL dd, yyyy").parse(s) 回答1: Change LLL to MMM and it should work. LLL is not defined (corrent value). You should look at Class SimpleDateFormat at official docs Common Pattern Strings for java.text.SimpleDateFormat As

问题 My current Java project requires me to work with dates and through my research and tinkering around I discovered the setLenient() method is defaulted to true . When I set it to false I begin to have problems with my code. I have a JFormattedTextField intialized with a SimpleDateFormat . For my project, I need to have / placeholders always present so using the answer to this question, I was able to install / s as place holders in the form of MM/dd/yyyy When the SimpleDateFormat is set to
