Class CategoryDisplayWindow
represents windows that display a single category
of experiences recorded by a user of the GoodStuff experience diary application.
Such a window enables the user to record new experiences in the category and
graphically highlights the user’s favorite among those experiences.
(Please note that the given version of the application does not support multiple categories. Persistent storage of experiences into files is also unsupported.)
Note to students: In this course, you don’t need to understand how this class works.
- Value parameters:
- category
the category of experiences to be displayed in this window

Compares the receiver object (this
) with the argument object (that
) for equivalence.
Compares the receiver object (this
) with the argument object (that
) for equivalence.
Any implementation of this method should be an equivalence relation:
- It is reflexive: for any instance
x
of typeAny
,x.equals(x)
should returntrue
. - It is symmetric: for any instances
x
andy
of typeAny
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any instances
x
,y
, andz
of typeAny
ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
.
If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is usually necessary to override hashCode
to ensure that
objects which are "equal" (o1.equals(o2)
returns true
) hash to the same scala.Int.
(o1.hashCode.equals(o2.hashCode)
).
- Value parameters:
- that
the object to compare against this object for equality.
- Returns:
true
if the receiver object is equivalent to the argument;false
otherwise.- Definition Classes

Calculate a hash code value for the object.
Calculate a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)
) yet
not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)
). Therefore, when overriding this method, be sure
to verify that the behavior is consistent with the equals
method.
- Returns:
the hash code value for this object.
