📝 FileReaderWriter (Java)

A simple Java console application for reading and writing text files with automatic timestamps.
It lets users write timestamped notes or messages into a text file and later read them back — all from the terminal.

🚀 Features

• ✅ Create or append to any text file
• 🕒 Auto-timestamped entries using LocalDateTime
• 📖 Read saved content directly from the file
• 💬 Simple interactive menu
• ⚙️ Handles missing files and I/O errors gracefully

---

🧠 How It Works

1. When you start the program, it asks for a filename (without extension).

2. You’ll see a menu:

   • 1️⃣ Write to file
   • 2️⃣ Read file
   • 3️⃣ Exit

3. When writing, each line is saved with a timestamp.

   • Type exit when you’re done writing.

4. When reading, the file’s contents (with timestamps) are displayed in the terminal.
