What kind of exceptions you have faced and how you handled them?
In Selenium: nosuchelement, nostaleexception, nosuchaframe common exception
In SQL: SQL exception
To handle it: try/catch block and throws keyword
(try / catch inside the block)
place try catch inside main method is easy
throws keyword is used within the method signature
disadvantage is: throws keyword whoever calls the method will
have to handle the exception again but with try/catch you handle once.
Try/catch is better way to handle it in utility class.
Next time you call method you don’t get any exceptions
