How do exceptions work in C++ and Java?

How do exceptions work in C++ and Java?

In C++, exceptions are handled using try, catch, and throw keywords. In Java, the mechanism is similar but has checked exceptions.

Can you explain the difference between checked and unchecked exceptions in Java?

Checked exceptions must be declared in a method's throws clause or handled with a try-catch block, while unchecked exceptions do not.

What about exception handling in C++? Are there checked exceptions?

C++ does not have checked exceptions. All exceptions are unchecked, and it's up to the programmer to handle them appropriately.

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

Sure! In C++, you might use:

try {
    // code that may throw
} catch (const std::exception& e) {
    // handle exception
}

In Java:

try {
    // code that may throw
} catch (Exception e) {
    // handle exception
}
