Files class provides several methods to create regular files, directories, symbolic links, and temporary files/directories.
These methods throw an IOException when an I/O error occurs during the file creation.
They throw an IOException if you attempt to create a file that already exists.
Most of the methods accept a varargs parameter of the FileAttribute type, which lets you specify the file attributes.
You can use the createFile() method to create a new regular file.
The file creation fails in case the file already exists, or the parent directory does not exist.
The following code shows how to create a new file. It attempts to create a Main.java file in your default directory.
The program prints the details of the file creation status.
import java.io.IOException; import java.nio.file.FileAlreadyExistsException; import java.nio.file.Files; import java.nio.file.NoSuchFileException; import java.nio.file.Path; import java.nio.file.Paths; public class Main { public static void main(String[] args) { Path p1 = Paths.get("test.txt"); try {/*w ww.j av a2 s . c o m*/ Files.createFile(p1); System.out.format("File created: %s%n", p1.toRealPath()); } catch (FileAlreadyExistsException e) { System.out.format("File %s already exists.%n", p1.normalize()); } catch (NoSuchFileException e) { System.out.format("Directory %s does not exists.%n", p1.normalize() .getParent()); } catch (IOException e) { e.printStackTrace(); } } }
