NIO2 API returns its own DirectoryStream object, which implements the Iterable interface. Moreover, the NIO2 API has the toRealPath() and normalize() methods that we can use to remove redundancies.Ĭonversion to URI can be done by using the toUri() methods: URI fileUri = file.toURI() Īlso, we can list the directory content: // java.io APIĭirectoryStream paths = Files.newDirectoryStream(path)
While the Path object is immutable, it returns a new instance. Path canonicalPath = path.toRealPath().normalize() Path absolutePath = path.toAbsolutePath() It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Next, we create an Instance of BufferedReader upon the file reader. Here we are creating an instance of FileReader by providing the path to file. File file new Path currentDirectoryPath Paths.get FileSystem fileSystem. Also, the Java 8 Streams which are generated from File IO resources need to be closed. // create file object for current folder. Below programs will illustrate the use of the getPath() function: Example 1: We are given a file object of a file, we have to get the path of the file object. To get the list of all the existing files in a directory this class provides the files class provides list() (returns names) and ListFiles (returns File objects) with different variants. Return value: The function returns a String value which is the Path of the given File object. (f.getPath ()) The following is an example to get the path of the file. java.io.File f file.getSelectedFile () Now, get the path of the selected file which we will get using the above method. To get the path of the selected file, at first get the selected file. String canonicalPathStr = file.getCanonicalPath() Note that, in Java File IO we need explicitly close all of the streams and readers that we create. The class named File of the java.io package represents a file or directory (path names) in the system.This class provides various methods to perform various operations on files/directories. Java 8 Object Oriented Programming Programming. String absolutePathStr = file.getAbsolutePath() To get absolute or canonical paths, we can use: // java.io API Be aware that, unlike the previous examples, most of them are performed directly on object instances. In the end, let's quickly look at methods in the File class for getting the filesystem path.
