    The java.io.File class in Java provides an abstract representation of file and directory pathnames. It offers a system-independent way to handle file paths, whether absolute or relative, and supports operations for file creation, deletion, querying, and directory listing.

    A File object does not represent the file’s content, but rather the pathname. It can point to an existing or non-existing file/directory.

    Key Features:

    • Path Handling: Supports absolute and relative paths, with system-dependent separators (File.separator and File.pathSeparator).

    • File Metadata: Methods like exists(), isFile(), isDirectory(), length(), lastModified().

    • File Operations: Create (createNewFile()), delete (delete()), rename (renameTo()), and set permissions (setReadable(), setWritable(), setExecutable()).

    • Directory Operations: List contents (list(), listFiles()), create directories (mkdir(), mkdirs()).

    • Integration with NIO: Convert to Path using toPath() for advanced file operations.

    Example Usage:

    import java.io.File;
    import java.io.IOException;

    public class FileExample {
    public static void main(String[] args) {
    File file = new File("example.txt");

    try {
    // Create new file if it doesn't exist
    if (file.createNewFile()) {
    System.out.println("File created: " + file.getName());
    } else {
    System.out.println("File already exists.");
    }

    // File properties
    System.out.println("Absolute Path: " + file.getAbsolutePath());
    System.out.println("Writable: " + file.canWrite());
    System.out.println("Readable: " + file.canRead());
    System.out.println("File Size: " + file.length() + " bytes");

    // Delete on JVM exit
    file.deleteOnExit();

    } catch (IOException e) {
    e.printStackTrace();
    }
    }
    }
