What is the exception hierarchy in C++ and Java?

Can you explain the exception hierarchy in C++ and Java?

Sure! In C++, exceptions are derived from the std::exception class, while in Java, they extend from the Throwable class.

What are the main types of exceptions in both languages?

In C++, you have standard exceptions like std::runtime_error and std::logic_error. In Java, you have checked exceptions like IOException and unchecked exceptions like NullPointerException.

How do you handle exceptions in C++ compared to Java?

In C++, you use try-catch blocks to handle exceptions, similar to Java. However, C++ does not have checked exceptions, so all exceptions are unchecked.

Can you give an example of exception handling in both languages?

Certainly! In C++, you might use:

try {
    throw std::runtime_error("Error occurred");
} catch (const std::exception& e) {
    std::cout << e.what();
}

In Java, it would look like:

try {
    throw new IOException("Error occurred");
} catch (IOException e) {
    System.out.println(e.getMessage());
}
