What is the reason for avoiding throwing exceptions of type RuntimeException in the code?

Avoiding throwing exceptions of type RuntimeException in code is related to the fact that they are unchecked exceptions, and their unexpected occurrence can lead to hard-to-debug errors and reduce the reliability of the program. Such exceptions usually indicate programming errors (e.g., NullPointerException, ArrayIndexOutOfBoundsException), which are better prevented through correct logic and checks rather than handled in try-catch blocks.

Reasons for avoidance:

• Lack of explicit control: RuntimeException does not require mandatory catching or declaration, making it difficult to understand where and why they might occur.
• Reduced readability and maintainability of code: Code with unexpected RuntimeException is harder to debug.
• It is better to use checked exceptions to explicitly indicate possible errors and force handling.

Thus, by avoiding throwing RuntimeException, a developer increases the reliability and predictability of the application's behavior.
