feat: Print backslashes using escape sequences in Java [backslash-escape]

🔑 Key: backslash-escape
🧠 Logic:
- Demonstrates how to print a single backslash (`\`) using `\\` (escape sequence).
- Prints file paths and double backslashes explicitly using:
  ➤ `"C:\\Program Files\\Java"` → prints: C:\Program Files\Java
  ➤ `"\\\\"` → prints: \\

📘 Purpose:
- Helps in displaying Windows file paths and backslash literals.
- Essential in strings where backslashes are syntactically significant (regex, file paths).

💡 Tip:
- Each `\\` results in one `\` in the output.
