- Java4090: the comparator interface
This module discusses and illustrates the use of the Comparator interface. The sorting order established by a Comparator may be different or may be the same as the natural order. A Comparator can be used to establish a sorting order for objects that don't have a natural ordering. The use of a Comparator is an alternative to the implementation of the Comparable interface.

Preface
This module is one of a series of modules designed to teach you about
Object-Oriented Programming (OOP) in general and the Java Collectionsframework in particular.
This module discusses and illustrates the use of the
Comparator interface. The sorting order established by a
Comparator may be different or may be the same as the natural order. A
Comparator can be used to establish a sorting order for objects that don't have a natural ordering. The use of a
Comparator is an alternative to the implementation of the
Comparable interface.
This module is also the first of several modules on the
Comparator interface. The purpose of the modules in this group is to teach you about theinteractions between the
Comparator interface and the Collections
Framework
, particularly with respect to the
Set ,
SortedSet ,
and
SortedMap interfaces of the Collections Framework. This module
discusses
Set and
SortedSet . A discussion of
SortedMap will be
deferred to a future module.
In addition to studying these modules, I strongly recommend that you study
the
Collections Trail in
Oracle's Java
Tutorials . The modules in this collection are intended to supplement and not
to replace those tutorials.

because it helps many people around the world to understand how to interact with other people and understand them well, for example at work (job).
Agreed 👍 There are many parts of our brains and behaviors, we really need to get to know. Blessings for everyone and happy Sunday!

Isn't practices worldwide, be it psychology, be it science. isn't much just a false belief of control over something the mind cannot truly comprehend?
compare and contrast skinner's perspective on personality development on freud
Skinner skipped the whole unconscious phenomenon and rather emphasized on classical conditioning

explain how nature and nurture affect the development and later the productivity of an individual.
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
and having a good philosophy of the world is like a sandwich and a peanut butter 👍
