The following Java program prints the names of the text files and jpeg files in the path D:\\ExampleDirectory separately. ExampleĪssume we have a folder named ExampleDirectory in the directory D with 7 files and 2 directories as − To get the file names based on extensions implement this interface as such and pass its object to the above specified list() method of the file class.
The FilenameFilter is an interface in Java with a single method. But the retuned array contains the filenames which are filtered based on the specified filter. File listFiles(FilenameFilter filter)Īmong these, the String list(FilenameFilter filter) method returns a String array containing the names of all the files and directories in the path represented by the current (File) object.To get the list of all the existing files in a directory this class provides five different methods to get the details of all files in a particular folder − This class provides various methods to perform various operations on files/directories. The class named File of the java.io package represents a file or directory (path names) in the system.
