Answer 1

The reason is that, What happens all of your conditions failed to execute ??

Possible solutions :

• You need to provide an else block there.When you provide a else block, then it is sure that always there is a chance to return the value, either in if or in else .

• A default return statement without regarding if-else, where the returning value should be decide in blocks.
