This is an example of how to create a new empty File. We are using the File class that is an abstract representation of file and directory pathnames. Creating a new empty file implies that you should:
- Create a new File instance by converting the given pathname string into an abstract pathname.
- Use
createNewFile()API method of File. This method atomically creates a new, empty file named by this abstract pathname if and only if a file with this name does not yet exist. The check for the existence of the file and the creation of the file if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the file.
Let’s take a look at the code snippet that follows:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | package com.javacodegeeks.snippets.core;import java.io.File;import java.io.IOException;public class CreateNewEmptyFile { public static void main(String[] args) { File file = new File("C://test.txt"); boolean fileCreated = false; try { fileCreated = file.createNewFile(); } catch (IOException ioe) { System.out.println("Error while creating empty file: " + ioe); } if (fileCreated) { System.out.println("Created empty file: " + file.getPath()); } else { System.out.println("Failed to create empty file: " + file.getPath()); } }} |
