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

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

In C++, exceptions are used for handling errors that can be caught and managed, while errors are typically serious issues that cannot be handled. In Java, exceptions are also used for error handling, but they are categorized into checked and unchecked exceptions.

Can you give examples of exceptions and errors in both languages?

Sure! In C++, an example of an exception is std::runtime_error, while an error could be a memory allocation failure. In Java, an example of a checked exception is IOException, and an unchecked exception could be NullPointerException.

How do you handle exceptions in C++ and Java?

In C++, you use try-catch blocks to handle exceptions. In Java, you also use try-catch blocks, but you can declare checked exceptions in the method signature using the throws keyword.

Are there any best practices for using exceptions?

Yes, some best practices include using exceptions for exceptional conditions only, avoiding using exceptions for control flow, and providing meaningful messages when throwing exceptions.
