do i need to handle checked exception in java code example

Example 1: Can we use catch statement for checked exceptions

If there is no chance of raising an exception in our code then we can’t 
declare catch block for handling checked exceptions. This raises compile time 
error if we try to handle checked exceptions when there is no possibility 
of causing exception.

Example 2: how to handle checked exceptions in java

I would either handle or declare. I Declare using THROWS keyword or handle by
using TRY&CATCH block. If I will use it again I would handle it. If it will
occur only once than I would use THROWS keyword
