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. In case of "regex", pattern is regular expression defined by java.util.regex.Pattern. Read java.util.regex.Pattern to get "regex" more. If you want to find a file that matches the pattern consider using FileVistor and implementing its methods to visit each file in a directory
