"this" is an implicit reference to the current object. all Objects have a this reference. It can be used to pass a reference to the current object to a method in another object.
super is used to refer to the parent class of the current object. This is useful if you wish an overriding method to refer to the version of the method in the parent class.

also this() and super() play a key role in constructor.
Check out the JLS for more info and a lil example: �8.8.5 Constructor Body

Hi Rajiv
There is no this in a static reference, for example the main() method.
