What is Core Java (1)

What is Core Java?

It is a part of the Java programming language that one can use for
developing or creating a general-purpose app. Its main focus is to
build such general applications. The J2SE (Java Standard Edition)
is known as Core Java. It mainly covers concepts of object-oriented
programming (OOP). Its main pillars are inheritance,
polymorphism, encapsulation, and abstraction. These are:

Inheritance – It allows one to make use of the already existing class
without even writing the code from the very beginning. It thus
ensures code reusability in a better way.

Polymorphism – It allows the writing of code in a certain way to
make the object behave in multiple ways.

Encapsulation – It combines methods and data into a single unit.

Abstraction – It allows the writing of a code in a way that hides the
details of implementation. It, in turn, reduces the complexity.
Allows writing the code in a way that hides the implementation
details to reduce complexity.

In addition, Core Java also covers concepts like AWT, threading,
swing, and collections. AWT and swing help in building powerful
GUIs (Graphical User Interfaces). Threading, furthermore, assists
in the simultaneous execution of multiple processes, and the
collections allow a user to manipulate a group of objects. All-in-all,
Core Java covers all the basic and fundamental Java programming
language concepts.

Definition

Core Java essentially shapes the venturing stone or basics of some
other more complex or higher types of Java. It additionally
incorporates Advanced Java. A client will not have the option to
create or see any application utilizing the JAVA EE (Java Enterprise
Edition) without the essentials and fundamental ideas of Core Java.
Java covers everything beginning from the rudimentary standards
of articles, classes, pecking order, legacy, and information types.

Regions or Topics

Core Java covers some topics like data types, OOP, operators,
exception handling, swing, threading, and collections.

Uses

Core Java helps a client in building a few broadly useful
applications. These applications are by and large autonomous at any
stage. Models incorporate different occasion arranging applications,
realistic computer games like snakes, and mini-computers.

Type of Application

This programming basically covers the socket, swings, AWT,
classes, collection objects, and thread concepts.

Architecture

Core Java utilizes the single-level design. In this manner, it is
known as an independent application. In a solitary level application,
there is zero outsider collaboration. Center Java utilizes gadget
capacity or pile stockpiling restricted to take care of the client's
requirements.

Edition/Version of Java

The J2SE (Java Standard Edition) falls under Core Java.

Expertise

You can't make or foster a high-level java application without
utilizing Core Java. It is essential for fostering all the high-level Java
applications.

Coding Platform

Core Java normally comes into play when writing on Java Standard
Edition (Java SE).

Reason

Core Java does not deal with socket programming, databases, etc.
