What are the best practices for exception handling in C++ and Java?

In C++, it's important to use try-catch blocks effectively and to avoid using exceptions for control flow. In Java, always catch specific exceptions and use finally blocks for cleanup.

Can you explain why using exceptions for control flow is discouraged?

Using exceptions for control flow can lead to code that is hard to read and maintain. It can also impact performance since throwing exceptions is generally more expensive than regular control flow.

What should I do in the catch block?

In the catch block, you should handle the exception appropriately, such as logging the error, cleaning up resources, and possibly rethrowing the exception if necessary.

Are there any specific libraries or tools that can help with exception handling?

Yes, in C++, you can use libraries like Boost for better exception handling. In Java, frameworks like Spring provide robust exception handling mechanisms.
