Deleting a File in Java

Using java.io.File:

import java.io.File;

public class DeleteFileExample {
    public static void main(String[] args) {
        // Specify the path of the file to be deleted
        String filePath = "path/to/your/file.txt";

        // Create a File object
        File file = new File(filePath);

        // Check if the file exists before attempting to delete
        if (file.exists()) {
            // Attempt to delete the file
            if (file.delete()) {
                System.out.println("File deleted successfully.");
            } else {
                System.out.println("Unable to delete the file.");
            }
        } else {
            System.out.println("File does not exist.");
        }
    }
}

Using java.nio.file.Files:

import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.io.IOException;

public class DeleteFileWithNIOExample {
    public static void main(String[] args) {
        // Specify the path of the file to be deleted
        String filePath = "path/to/your/file.txt";

        // Create a Path object
        Path path = Paths.get(filePath);

        try {
            // Attempt to delete the file using Files.delete
            Files.delete(path);
            System.out.println("File deleted successfully.");
        } catch (IOException e) {
            System.out.println("Unable to delete the file.");
            e.printStackTrace();
        }
    }
}

In both examples:

• Specify the path of the file you want to delete.
• Create a File object or a Path object.
• Check if the file exists (optional).
• Use the delete() method of the File class or Files.delete() method to delete the file.

Make sure to handle exceptions appropriately, especially when working with file I/O, as file deletion operations may throw IOException. Additionally, it's good practice to check whether the file exists before attempting to delete it to avoid unnecessary errors.
