feat: Use escape sequences to print double quotes in strings [quote-escape]

🔑 Key: quote-escape
🧠 Logic:
- To include double quotes (`"`) within a string in Java, use the escape character (`\"`).
- Example:
  ➤ `"She said, \"Hello!\""` → prints: She said, "Hello!"
  ➤ `"This string contains \"quotes\"."` → prints: This string contains "quotes".

📘 Purpose:
- Useful for formatting dialogue, JSON strings, or quoted output in terminals and files.
- Prevents syntax errors that occur when raw quotes are misinterpreted as string boundaries.
