Modular Java File Operations

Let’s create a simple Java project that demonstrates file operations, including creating a file, writing to it, reading from it, and finally deleting the file. This project could represent a simple note-taking application where users can add notes to a file, read their notes back, and choose to delete the notes file when they are done.

To organize the simple note-taking application more effectively, we can separate each task (create, write, read, delete) into different classes. This approach improves the project’s structure and makes the code more modular and maintainable. Finally, we’ll combine all these operations in the main class.

Step 1: FileCreator.java

Handles file creation.

Step 2: FileWriterUtil.java

Manages writing content to the file.

Step 3: FileReaderUtil.java

Facilitates reading from the file.

Step 4: FileDeleter.java

Handles file deletion.

Main Class: SimpleNoteApp

Combines all operations.

This simple note-taking application demonstrates the core file operations in Java. It allows the user to add notes, read all notes back, and decide whether to delete the notes file at the end of the session, showcasing practical usage of creating, writing to, reading from, and deleting files.

The note-taking application divides responsibilities into separate classes, each handling a specific aspect of file management. This modular approach not only makes the code cleaner and more organized but also demonstrates a basic principle of object-oriented programming: separation of concerns.
