What potential problems can arise from improper use of exceptions in code?

Answer from AI
Improper use of exceptions in code can lead to several problems:
- Performance loss: frequent creation and handling of exceptions are costly.
- Error hiding: if exceptions are caught and ignored without logging, errors remain unnoticed.
- Maintenance difficulty: excessive or incorrect use of exceptions complicates understanding the flow of execution.
- Violation of program logic: using exceptions to control normal flow (e.g., instead of conditional statements) reduces readability and reliability.
Example of bad practice:
try {
int result = Integer.parseInt(input);
} catch (Exception e) {
// Ignoring error, which can lead to hidden bugs
}
It is better to explicitly handle expected exceptions and not use them for normal flow control.
