NullPointerException is a RuntimeException . Runtime exceptions are critical and cannot be caught at compile time. They crash the program at run time if they are not handled properly. When a class is instantiated, its object is stored in computer memory. The NullPointerExceptions (http://net-informations.com/java/cjava/null.htm) occur when you try to use a reference that points to no location in memory (null) as though it were referencing an object. These include:
- Calling the instance method of a null object.
- Accessing or modifying the field of a null object.
- Throwing null as if it were a Throwable value.
