java parsing date formatting simpledateformat
I have encountered a very weird behavior while using SimpleDateFormat for parsing a string to a date. Consider the following unit test:@Test public void testParse() throws ParseException {DateFormat dateFormat = new SimpleDateFormat(“yyyyMMdd”);String dateStr = “2012-12-21”;Date parsedDate = dateFormat.parse(dateStr);Calendar date = Calendar.getInstance();date.setTime(parsedDate);Assert.assertEquals(2012, date.get(Calendar.YEAR));Assert.assertEquals(11, date.get(Calendar.MONTH)); // yeah, Calend

java regex string split
I’m making a text based dice roller. It takes in strings like “2d10+5” and returns a string as a result of the roll(s). My problem is showing up in the tokenizer that splits the string into useful parts for me to parse into information.String[] tokens = message.split(“(?=[dk\\+\\-])”); This is yielding strange, unexpected results. I don’t know exactly what is causing them. It could be the regex, my misunderstanding, or Java just being Java. Here’s what’s happening: 3d6+4 yields the string array

java oop constructor setter
I know that private instance variables are accessed through their public getters and setters method.But when I generate constructors with the help of IDE, it initializes instance variables directly instead of initializing them through their setter methods.Q1. So should I change the IDE generated code for constructors to initialize those instance variables through their setter methods.Q2. If yes, then why IDE don’t generate constructors code in that way?============================= EDITED ======

java junit
I’m trying to implement unit testing for aproject, it uses a legacy “utility” project that is littered with static methods and many of the classes are final or their methods are final. I’m not able to update the legacy project at all.JMock and EasyMock both choke on final methods, and I don’t see a nice way to test the static calls. What techniques are there to test these?

I’ve spent about 6 hours on this so far, and been hitting nothing but roadblocks. The general premise is that there is some row in a ListView (whether it’s generated by the adapter, or added as a header view) that contains an EditText widget and a Button. All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row — even if I have to explicitly identify the row — that has a focusable child, I want that ch
