In Java create file tutorial, we show how to create a file in Java. We create files with built-in classes including
File
, FileOutputStream
, andFiles
. We also use two third-party libraries: Apache Commons IO and Google Guava.- Before Java 7, for writing bytes (image) to a file, we use FileOutputStream; for writing characters (text) to a file, we use FileWriter, and usually wrapped by a BufferedWriter to gain performance. In Java 7, there is a new NIO class named java.nio.file.Files, and we can use Files.write to write both bytes and characters.

If you want to append text to an existing file, pass a boolean flag of true to constructor of the writer class: FileWriter writer = new FileWriter('MyFile.txt', true); The following example uses a BufferedReader that wraps a FileReader to append text to an existing file.
- Jan 21, 2015 Files.write is best way to create a new file in Java and it should be your preferred approach in future if you are not already using it. This method writes lines of text to the created file. Each line is a char sequence and is written to the file in sequence with each line terminated by the platform’s line separator.
A computer file is a computer resource for recording data discretely in a computer storage device.
File f = new File('C: a b test.txt'); f.mkdirs; f.createNewFile; Notice I changed the forward slashes to double back slashes for paths in Windows File System. This will create an empty file on the given path.
The tutorials shows five ways to create a file in Java. The examples create empty files.
Java creating file with File
The
File's
createNewFile()
method creates a new, empty file named by the pathname if a file with this name does not yet exist. JavaCreateFileEx.java
The
createNewFile()
returns true if the named file doesnot exist and was successfully created; false if the named file already exists.Java creating file with FileOutputStream
In the second example, we create a new, empty file with
FileOutputStream
.The file is created when
FileOutputStream

is thrown if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason.Java creating file with Files
Java 7 introduced
Files
, which consists exclusively of static methods that operate on files, directories, or other types of files. Its createFile()
method creates a new and empty file, failing if the file already exists.JavaCreateFileEx3.java
The example creates a new, empty file with
Files

A
Path
object is created. It is used to locate a file in a file system. The new file is created with
Files.createFile()
. Magic flowers living wallpaper & screen saver 2 1.FileAlreadyExistsException
is thrown if the file already exists.Java creating file with Apache Commons IO
The next example creates a file with Apache Commons IO library.
For the project we need the
commons-io
dependency.The new file is created with
FileUtils.touch()
method.Java Create A File With Text
Java creating file with Google Guava
In the following example, we create a new file with Google Guavalibrary.
For the project we need the
guava
dependency.JavaCreateFileEx5.java
The new file is created with
Files.touch()
. It acceptsa File
as a parameter.In this tutorial, we have shown several ways how to create a file in Java. We have used built-in toolsand third-party libraries.
List all Java tutorials.
Here is a code example for creating text file and put some texts in it. This program will create a file called
write.txt
. To create and write a text file we do the following steps:Create Text File Java
Below is the complete code snippet:
