Answers for "path matcher java"

path matcher java

Tells you if a file matches your pattern

FileSystem fileSystem = FileSystems.getDefault();
		PathMatcher pathMatcher = fileSystem.getPathMatcher("glob:**/testFile.?");
		Path path = Paths.get("D:/cp/testFile.t");
		System.out.println(pathMatcher.matches(path));

The "glob:" says that we are glob. You can also regex
* It matches zero , one or more than one characters. 
  While matching, it will not cross directories boundaries.
** It does the same as * but it crosses the directory boundaries.
? It matches only one character for the given name.
\ It helps to avoid characters to be interpreted as special characters.
[] In a set of characters, only single character is matched. 
  If (-) hyphen is used then, it matches a range of characters. 
  Example: [efg] matches "e","f" or "g" . [a-d] matches a range from a to d.
{} It helps to matches the group of sub patterns.
