Exceptions are the unwanted and unexpected event of a program that is never desired by a programmer but has to deal with it so many times. The bright side is that it is possible with the object-oriented language Java to mitigate those undesirable events through a concept called ‘Exception Handling in Java’. It does not repair the exception but provides an alternate way to deal with it.

There can be many reasons for an exception to occur including entry of incorrect data, hardware failure, connection failure, server down, etc. Thus, exception handling is and always will be important in the course of learning Java as it helps to assure the normal flow of a program at the time an unexpected event occurs. Ignoring exceptions may cause the entire software to crash and may result in loss of data.

Now that we got an idea about exceptions and exception handling, let’s dive into it in detail and also understand how Java helps in handling exceptions.
