2026 QUESTIONS WITH 100% CORRECT
ANSWERS GRADED A+
⩥ modulo. Answer: similar to a remainder, calculated using "clock
arithmetic". when a negative number is "modded", it goes "counter-
clockwise," returning a negative value
⩥ standard methods. Answer: putting highly reused methods into an
interface so they're described in exactly one place
⩥ single point of control. Answer: creating a single place to change code
that affects many others
⩥ kernel (primary) methods. Answer: primary methods that are deemed
being special enough to go into their own interface
⩥ secondary methods. Answer: methods that are more "powerful" than
kernel methods, introduced to make a component readily usable in client
code
⩥ constructor. Answer: a method that creates an instance of a class
, ⩥ no-argument constructor. Answer: default constructor, takes no
arguments
⩥ copy constructor. Answer: returns a copy of the parameter value
⩥ instance method. Answer: methods that are called by a specific object
⩥ distinguished formal parameter. Answer: this
⩥ receiver. Answer: object an instance method is called on
⩥ parameter mode. Answer: the effect the parameter will have on the
object
⩥ mutable. Answer: object can be modified
⩥ #<variable_name>. Answer: # represents the old (incoming) variable
value
⩥ updates parameter mode. Answer: signifies that the parameter may
change the object
does not ensures parameter restoration
