https://www.sololearn.com/Course/Java/?ref=app An exception is a problem that occurs during program execution. Exceptions cause abnormal termination of the program. Exception handling is a powerful mechanism that handles runtime errors to maintain normal application flow. An exception can occur for many different reasons. Some examples: - A user has entered invalid data. - A file that needs to be opened cannot be found. - A network connection has been lost in the middle of communications. - Insufficient memory and other issues related to physical resources.

you can call yourself a good programmer if you know how to use and where to use exception handling. In live project implementation it is far considered in order to make a app or web user friendly. instead of throwing errors like NullException or IndexOutOfBound you can send user a pretty good response using try catch handling.
