Java File.createFile method. The File.createFile is a method of File class which belongs to java.nio.file package. It also provides support for files. The nio package is buffer-oriented. The createFile method is also used to create a new, empty file. We don't need to close the resources when using this method. It is an advantage. How to create a file in a directory in java? Ask Question Asked 9 years, 4 months ago. Import java.nio.file.Files; import java.nio.file.Path; import java.nio.file. File.createNewFile java.io.File class can be used to create a new File in Java. When we initialize File object, we provide the file name and then we can call createNewFile method to create new file in Java. File createNewFile method returns true if new file is created and false if file already exists. This method also throws java.io.IOException when it's not able to create the file.
In this article You'll learn how to create a webpage that gives a list of the files in a folder. This example uses 'client-side' Java Script. Client side Java Script that lets the public view a directory list of files on your server is considered to be dangerous. You would need to give the webpage special security privileges to work. This example is for use with Internet Explorer Web browser on your local computer. For your web site, you would use a server-side ASP file. In that case the code would be very similar, but easier.
The first step for the code is to find out what folder it's in. With a webpage, that information is contained in the document location object. We then pass that folder path to a FileSystemObject. Unfortunately, the format of the local path returned by the location object is not compatible with the FileSystemObject.

Equivalent path required by FileSystemObject:

To make the path compatible, first we use some string object methods to remove the 'file:///' from the beginning of the path, and to remove the '/filename.ext' from the end of the path. The code for this is shown below.
Next we use escape characters and regular expressions to replace the forward-slashes with back-slashes and replace incompatible local path characters with web path characters. The code for this is shown below.
There are certain characters in Internet URLs, like that returned by the location object, that are incompatible with local file paths. For example Windows uses back-slashes in file paths while the Internet uses forward-slashes in URLs. A blank space is acceptable in windows file paths, but must be represented with the %20 character code in Internet URLs.
The first line of code above uses a regular expression in the string object's replace method. Regular expressions is too complex of a subject to go into detail here, but the expression ///g means 'all forward slashes'. The second parameter passed to the replace method is a string meaning two back-slashes. Since, in code, a back-slash indicates an escape character, you need to escape each back-slash. (Even to me that sounds like double-talk, but take my word for it. Escape characters is too complex of a subject to go into detail here.
The second line of code replaces any %20 space character codes in the Internet path with a plain old space. Now we're prepared for business. Shown below is the code to create a Scripting.FileSystemObject and pass it's GetFolder method the path we have created, and then save the Folder's FileCollection.
Next, we create an array and an Enumerator object, and use the Enumerator object in a loop to step through the FileCollection, placing all the filenames (actually all the files complete directory file paths) into the array elements. The code for this is shown below.
