What is an Exception?<\/h2>\n

An exception is an event that interrupts the execution of the program without giving the output. In simple words, any issue which stops your script in between the execution is an exception. When an exception occurs in the program then It halts the normal flow of the program and creates an object. The exception object contains a lot of debugging information such as method name, line number where the exception occurred and type of exception.
