matcher

Directly from this Java Oracle tutorial: Two asterisks, **, works like * but crosses directory boundaries. This syntax is generally used for matching complete paths. Could anybody do a real example out of it? What do they mean with "crosses directory boundary"? Crossing the directory boundary, I imagine something like checking the file from root to getNameCount()-1 . Again a real example explaining the difference between * and ** in practice would be great. The javadoc for FileSystem#getPathMatcher() has some pretty good examples and explanations *.java Matches a path that represents a file

This question already has an answer here: SCJP6 regex issue 1 answer I am testing a small stub of Matcher and Pattern class...see the following small stub.. package scjp2.escape.sequence.examples; import java.util.regex.Matcher; import java.util.regex.Pattern; public class Sample_19 { public static void main(String a[]){ String stream = "ab34ef"; Pattern pattern = Pattern.compile("\\d*"); //HERE * IS GREEDY QUANTIFIER THAT LOOKS FOR ZERO TO MANY COMBINATION THAT //START WITH NUMBER Matcher matcher = pattern.matcher(stream); while(matcher.find()){ System.out.print(matcher.start()+matcher.group(

I am confused on what's the difference between them, and which one to choose in which case. Some difference might be obvious, like any and eq , but I'm including them all just to be sure. I wonder about their differences because I came across this problem: I have this POST method in a Controller class public Response doSomething(@ResponseBody Request request) { return someService.doSomething(request); } And would like to perform a unit test on that controller. I have two versions. The first one is the simple one, like this @Test public void testDoSomething() { //initialize ObjectMapper mapper

I know this has been asked but I am unable to fix it For a book object with body (spanish): "quiero mas dinero" (actually quite a bit longer) My Matcher keeps returning 0 for: String s="mas"; // this is for testing, comes from a List<String> int hit=0; Pattern p=Pattern.compile(s,Pattern.CASE_INSENSITIVE); Matcher m = p.matcher(mybooks.get(i).getBody()); m.find(); System.out.println(s+" "+m.groupCount()+" " +mybooks.get(i).getBody()); hit+=m.groupCount(); I keep getting "mas 0 quiero mas dinero" on console. Why oh why? From the javadoc of Matcher.groupCount() : Returns the number of capturing

I am trying to create a mock for a call. Say I have this method I am trying to stub out: class ClassA { public String getString(String a) { return a + "hey"; } } What I am trying to mock out is: 1st instance is when(classA.getString(eq("a")).thenReturn(...);` in the same test case when(classA.getString([anything that is not a])).thenReturn(somethingelse); The 2nd case is my question: How do I match anyString() other than "a"? With Mockito framework, you can use AdditionalMatchers ClassA classA = Mockito.mock(ClassA.class); Mockito.when(classA.getString(Matchers.eq("a"))).thenReturn("something"
