When should you prefer suppressed exceptions and when should you avoid it?

Suppressed exceptions in Java are exceptions that are thrown during the execution of a try-with-resources statement when resources are being closed, and they do not prevent the primary exception from being thrown. Understanding when to use or avoid suppressed exceptions can greatly impact error handling in your applications.

When to Prefer Suppressed Exceptions

• Resource Management: If you are managing resources (e.g., closing streams, database connections), suppressed exceptions help capture errors that occur during the closure without losing sight of the primary exception.
• Comprehensive Error Reporting: Suppressed exceptions provide a complete view of what went wrong. They allow you to handle multiple failure points effectively.

When to Avoid Suppressed Exceptions

• Unclear Error Context: If the additional exceptions do not provide meaningful insights into the primary error and may confuse the user or developer.
• Overwhelming Information: If many suppressed exceptions could clutter error logs or make it difficult to trace the root cause of a problem.

Example of Using Suppressed Exceptions

// Example in Java showing suppressed exceptions
try (BufferedReader reader = new BufferedReader(new FileReader("sample.txt"))) {
    // Perform file operations
} catch (IOException e) {
    System.err.println("An error occurred: " + e.getMessage());
    for (Throwable suppressed : e.getSuppressed()) {
        System.err.println("Suppressed exception: " + suppressed.getMessage());
    }
}
