Exceptions vs Errors: What’s the actual difference?

### 📌 The Ultimate Guide: Error vs Exception (Why they are NOT the same)

---

### 🛑 1. What is an Error?

Errors represent severe problems that an application should not try to catch. They are usually related to the system environment.

* **Origin:** System-level or hardware issues.

* **Recoverability:** **Irrecoverable.** The program terminates immediately.

* **Handling:** Cannot be handled using standard code (`try-catch`).

* **Common Examples:** `OutOfMemoryError`, `StackOverflowError`, `HardwareFailureError`.

---

### ⚠️ 2. What is an Exception?

Exceptions represent conditions that a reasonable application might want to catch. They are caused by the program's code logic.

* **Origin:** Application-level or logical code mistakes.

* **Recoverability:** **Recoverable.** You can save the application from crashing.

* **Handling:** Easily handled using `try-catch-finally` blocks.

* **Common Examples:** `NullPointerException`, `FileNotFoundException`, `ArithmeticException`.
