Explain try and catch exception in java?
Why use exceptions instead of return values? 1. Forces error checking 2. Cleans up your code through separating the normal case from the exceptional case. (The code isn't littered along with a lot of if-else blocks checking return values.) 3. Low overhead for non-exceptional case

Java throws Exception objects to denotes a problem. These cannot be ignored.try-catchtry-catch public class HelloThere {

}
