geet, you'll be asked to change your name to the JavaRanch standards. Until then, in a nutshell:
this is a reference to the instance of the object that a non-static method is executing against.
super is a way to reference the superclass from which the current class is dervied. It could be used to differentiate between identifiers that are the same in the derived and super classes. When used as a method name in a constructor, it references the constructor of the superclass.
static is a keyword that specifies that a member or method does not "belong" to a specific instance of the class, but to the class as a whole. Hence, within a static method, there is no this.
