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) Below is the simple syntax to use dataInputStream in java: DataInputStreamdataInputStream new DataInputStream(newFileInputStream('filename')) doubletoreadDouble input.readDouble() inttoread input.read() float toreadFloat input.readFloat() inttoreadInt input.readInt() input. While the Path object is immutable, it returns a new instance. Path canonicalPath = path.toRealPath().normalize() Path absolutePath = path.toAbsolutePath() As for the actual path, you CAN use something to the order of ' ( 'path/to/resource.ext' )' BUT the major thing to note is that it will work from whatever classpath. String canonicalPathStr = file.getCanonicalPath() 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.
