Creating Files and Directories

File I/O Classes: Creating Files and Directories

1. File Class:

   - Represents a file or directory path.

   - Provides methods for creating new files and directories.

   File file = new File("newFile.txt");

   try {

       if (file.createNewFile()) {

           System.out.println("File created: " + file.getName());

       } else {

           System.out.println("File already exists.");

       }

   } catch (IOException e) {

       System.out.println("An error occurred.");

       e.printStackTrace();

   }

2. mkdir() Method:

   - Creates a directory.

   File directory = new File("newDirectory");

   if (directory.mkdir()) {

       System.out.println("Directory created: " + directory.getName());

   } else {

       System.out.println("Directory already exists.");

   }

3. mkdirs() Method:

   - Creates a directory and its parent directories if they do not exist.

   File directories = new File("newDirectories/childDirectory");

   if (directories.mkdirs()) {

       System.out.println("Directories created: " + directories.getName());

   } else {

       System.out.println("Directories already exist.");

   }

4. Path Class (Java NIO):

   - Provides methods for manipulating file paths.

   - Can create files and directories using Files class.

   Path path = Paths.get("newFile.txt");

   try {

       Files.createFile(path);

       System.out.println("File created: " + path.getFileName());

   } catch (IOException e) {

       System.out.println("An error occurred.");

       e.printStackTrace();

   }

5. Files Class (Java NIO):

   - Provides methods for file operations.

   - Can create directories and files.

   Path directoryPath = Paths.get("newDirectory");

   try {

       Files.createDirectory(directoryPath);

       System.out.println("Directory created: " + directoryPath.getFileName());

   } catch (IOException e) {

       System.out.println("An error occurred.");

       e.printStackTrace();

   }

These examples illustrate different ways to create files and directories in Java using various file I/O classes and methods.
