Java key word 'this' always refers to the current object, like; this.doSomething() for
a method, or this.myRefVar for a member variable. The presence of 'this' is often
inferred by the compiler, as doSomething() and this.doSomething() mean the same
thing. Also, 'this' is often used within a constructor to invoke a different constructor,
as in; this(parm1, parm2, etc). The specific constructor invoked is based on matching
up the constructor and call parameter types. Key word 'super' is used in the same ways,
but refers to constructors, methods and member variables not in the current object, but
rather, above it in the inheritance tree. Does this help?
