Inheritance and Scoping

Examples:

super(xxx) // calls a superclass constructor

super.xxx // accesses superclass’ variable

super.xxx( ) // calls superclass’ method

this(xxx) // calls a current-class constructor

this.xxx // accesses current class’s variable

this.xxx( ) // calls current class’ method

Note: cannot do

super.super<something>

(can achieve this effect via casting,

but rarely should; details later...)
