Anexceptionis an error event that can happen during the execution of a program and disrupts its normal flow. Java provides a robust and object-oriented way to handle exception scenarios known as Java Exception Handling. Exceptions in Java can arise from different kinds of situations such as wrong...
3. Java throw and throws keyword The Javathrowkeyword is used to explicitly throw a single exception. When wethrowan exception, the flow of the program moves from thetryblock to thecatchblock. Example: Exception handling using Java throw classMain{publicstaticvoiddivideByZero(){// throw an ex...

I believe continuing this trend for future programming languages would be a mistake, for two reasons....
