What are the differences between exceptions in C++ and Java?

What are the main differences between exceptions in C++ and Java?

C++ uses a more manual approach with try-catch blocks, while Java has a built-in exception hierarchy and checked exceptions.

Can you explain what checked exceptions are in Java?

Checked exceptions in Java are exceptions that must be either caught or declared in the method signature, ensuring error handling.

How does C++ handle exceptions differently?

C++ does not have checked exceptions; all exceptions are unchecked, meaning they don't need to be declared or caught explicitly.

Are there any performance differences between the two?

Yes, C++ exceptions can be more efficient since they don't require the overhead of checked exceptions, but this can vary based on implementation.
