What is the purpose of try-catch-finally in programming?

The try-catch-finally construct is used for error handling in programming. It allows you to try a block of code, catch exceptions if they occur, and execute cleanup code in the finally block.

Can you give me an example of how it works?

Sure! In Java, you might write:

try {
    // code that may throw an exception
} catch (Exception e) {
    // handle the exception
} finally {
    // cleanup code that runs regardless of an exception
}

What happens if there is no exception?

If no exception occurs, the code in the catch block is skipped, but the code in the finally block will still execute.

Is it possible to have multiple catch blocks?

Yes, you can have multiple catch blocks to handle different types of exceptions separately.
