Why we have both: the throws clause in main method and try-catch block? Task task0908 Exception while working with strings: As i understood from the lesson 4 we handle exceptions in either throw clause (here: public static void main(String[] args) throws Exception) or with try-catch block. Why we have both in this example? thank you

Use the keyboard to enter a nam

Runs fine and gives answer but validation says infinite loop.not sure why this gives me an infinite loop error. I run it locally in IntelliJ as well as here and it gives me the correct answer each time. Validation fails and it says "looks like you have an infinite loop"... I don't see how since the code finishes and exits each time.
