As core java developer you can effectively be utilizing the available resources in libraries & gradually rise in this field of core java topics & advanced java concepts.

Oops Concept in Java

The best way to learn java is to be familiar with core java topics which are closer to the Object oriented programming concepts.

Objects are real-world entity such as an object like chair, table, computer, watch, etc.

In core java syllabus Object-Oriented Programming refers to methodology or standards which lets one design a program using classes and objects. Java is also an Object Oriented Programming langauge which has got numerous inbuild resources library available thanks to broadest range of developers community contributing to it.

It lets java for beginners to learn java software through relating to core OOPS concepts that let them develop and maintain with providing some core concepts such as :

  • Object
  • Class
  • inheritance basics
  • The concept & Principles of Polymorphism
  • Concepts & principles of Abstraction &
  • Encapsulation

Also when one focuses on core java basic concepts one has to get familiarize with terms which often come under the core java syllabus and which is used in basic Object-Oriented design such as

  • Coupling
  • Cohesion
  • Association
  • Aggregation
  • Composition

Question & Answer related to Top 3 Core java basic concepts

Q. What are basic Java concepts?

A. OOPs concepts in Java are the main concepts that are part of core java topics & also used in advanced java concepts and form its building blocks.

Client side scripting part that comprises of JEE (viz Java Enterprise Edition which focuses on Server implementation part , J2EE & the Java frameworks).

Q. Can I learn Java in 6 months?

A. Yes why not as one when starts as java for beginners and starts learning the core java basic concepts then more to more deeper topics which are OOPS centric concepts , this fascinating world of Java.

One can be good at Java if one is good at grasping core java topics and proves his or her practical knowledge through continuous practice

Q. Is core Java enough to get a job?

A. Yes when one gets good knowledge about core Java and has clear fundamentals on core java basic concepts one becomes included in the “preferred list of candidates” by IT recruiters.
