What is a try-catch-finally example in programming?

Can you explain what a try-catch-finally block is in programming?

Sure! A try-catch-finally block is used to handle exceptions in programming. The 'try' block contains code that might throw an error, the 'catch' block handles the error if it occurs, and the 'finally' block executes code after the try and catch blocks, regardless of whether an error occurred.

Can you give me a simple example of how it works?

Of course! Here's a simple example in Java:

try {
    int result = 10 / 0; // This will throw an exception
} catch (ArithmeticException e) {
    System.out.println("Cannot divide by zero!");
} finally {
    System.out.println("This will always execute.");
}

In this example, the catch block handles the division by zero error.

What happens if there is no exception?

If there is no exception, the code in the 'try' block executes normally, and the 'catch' block is skipped. 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. This allows for more specific error handling.
