This one took me more time than the others to understand, thanks to the debugging utility in intelij idea.


Could you explain to me this line :
break (T) (Object) (Integer.valueOf(129) == 129 ? 5 : 7);


What will be the result of the break statement, do we return from the method or do we break the switch.
For wich reason you convert the value to (Object) to (T) type. I tested without this conversion and it worked fine.


Thanks for the channel.
