This is a error that occurs at the run time, when an application or a program tries to access the object reference which has a null value stored in it, then this exception occurs in order to overcome this exception you need to to check your code whether you define a variable but have not given a value to it so bascially it automatically takes a garbage null value thats why this error occurs.

Hope this will help you.
