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

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

In Java, checked exceptions must be declared in a method's throws clause, while unchecked exceptions do not. C++ does not have a formal checked/unchecked distinction.

Can you give examples of each type of exception?

Sure! In Java, an example of a checked exception is IOException, while an unchecked exception is NullPointerException. In C++, exceptions are generally unchecked.

Why does Java have checked exceptions while C++ does not?

Java's checked exceptions are designed to enforce error handling at compile time, promoting robust code. C++ relies on the programmer to handle exceptions.

Are there any advantages to using checked exceptions?

Yes, checked exceptions can lead to better error handling and clearer API contracts, as they force developers to consider potential errors.
