Basic exception handling

Exception handling mechanism: suspend problem handling, not in the current function, but in his caller (get on the bus first, then make up the ticket)

What is an exception: anything can be thought of as an exception, and an error is just a kind of exception.

Once an exception is thrown, it is not handled. If an exception is thrown, the default abort function is called to terminate the program.

Catch and handle exceptions:

Throw throws an exception: (the value is of any type, but it's just a reference for us to handle the exception, similar to the return value.)

Try (check, catch) and catch (handle exceptions): must appear together, and their parentheses {} cannot be omitted

Tip: anything can be thought of as an exception, and an error is just one of the exceptions-there is a situation that does not make the program work properly
