What are common exception handling techniques?

Common exception handling techniques include:

1. Try-Catch Blocks:

   • Use try to wrap code that may throw an exception and catch to handle the exception.

   try {
       // Code that may throw an exception
   } catch (ExceptionType e) {
       // Handle the exception
   }

2. Finally Block:

   • Use finally to execute code that should run regardless of whether an exception occurred, often for cleanup.

   try {
       // Code that may throw an exception
   } catch (ExceptionType e) {
       // Handle the exception
   } finally {
       // Cleanup code
   }

3. Throwing Exceptions:

   • Use throw to signal an error condition by throwing an exception.

   throw new ExceptionType("Error message");

4. Custom Exceptions:

   • Create your own exception classes to handle specific error conditions in a more meaningful way.

   public class MyCustomException extends Exception {
       public MyCustomException(String message) {
           super(message);
       }
   }

5. Multiple Catch Blocks:

   • Handle different types of exceptions separately using multiple catch blocks.

   try {
       // Code that may throw multiple exceptions
   } catch (IOException e) {
       // Handle IOException
   } catch (SQLException e) {
       // Handle SQLException
   }

6. Logging Exceptions:

   • Use logging frameworks to log exceptions for debugging and monitoring purposes.

   logger.error("An error occurred", e);

These techniques help create robust applications that can gracefully handle errors and maintain a good user experience. If you need examples or further details on any technique, feel free to ask!
