Exception handling is a crucial part of writing robust and maintainable Java applications. However, many developers misuse exceptions, leading to poor performance, hard-to-debug issues, and unreadable code.

In this article, we’ll cover 10 common mistakes developers make while handling exceptions in Java and how to fix them properly. Let’s dive in! 🔥

🔴 1️⃣ Catching Generic Exceptions (Exception or Throwable)

❌ Mistake: Catching Exception or Throwable Without a Reason

Catching a generic exception hides specific errors and makes debugging difficult.

try {
    int result = 10 / 0;  // ArithmeticException
} catch (Exception e) {  // ❌ Bad practice
    System.out.println("An error occurred!");
}

✅ Best Practice: Catch Specific Exceptions

• Always catch specific exceptions to provide better error handling.
• This improves readability and debugging.

try {
    int result = 10 / 0;
} catch (ArithmeticException e) {  // ✅ Good practice
    System.out.println("Cannot divide by zero!");
}

🔹 Fix: Avoid catching broad exceptions unless you truly need to.
