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

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.
