Before you begin practicing many forms of examples provided On this reference, we think that you will be now informed about Laptop or computer systems and computer programming languages.
def z attempt def i = 7, j = 0 try def k = i / j assert Phony //by no means reached because of Exception in preceding line last but not least z = 'reached here' //always executed whether or not Exception thrown catch ( e ) assert e in ArithmeticException assert z == 'arrived at below'
