How do I use finally in try blocks?

The finally block is used in conjunction with try and catch blocks to ensure that certain code runs regardless of whether an exception was thrown or not. It’s typically used for cleanup actions.

Can you give me an example of how it works?

Sure! Here's a simple example in Java:

try {
    // Code that may throw an exception
    int result = 10 / 0;
} catch (ArithmeticException e) {
    System.out.println("Caught an exception: " + e.getMessage());
} finally {
    System.out.println("This will always execute.");
}

In this case, the message in the finally block will execute even if an exception occurs.

What happens if there is no exception?

If there is no exception, the code in the finally block will still execute after the try block completes successfully.

Is it possible to have multiple catch blocks?

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