Java is an object-oriented programming (OOP) language, which means concepts or things are represented as “objects” that have data fields and methods. In object-oriented programming, models called “objects” represent either a programming entity or an abstract concept. These objects are created and assembled independently of one another but can work with each other in logical ways.

It is explained how to install Java Development Kit (JDK) on Windows.

Java is a very versatile language. Several fields use Java, including Android app development, desktop applications that work on many operating systems, server-side applications, and more. The virtual machine required to run Java programs has been ported to numerous operating systems allowing Java to run on virtually all hardware. According to the TIOBE index, Java has consistently been in the top 3 most-used and popular languages since its initial release in the 1990s.

learn core java programming: Java is a programming language and platform initially developed by Sun Microsystems and now owned by Oracle. Java is inspired by C and C++ and uses an object-oriented programming model, which means that concepts or things are represented as “objects” that have data fields and methods. One of the biggest advantages of Java is that it runs on a Java Virtual Machine (JVM), meaning that you can execute Java code on any platform that has a JVM, without re-compilation. This is different from C and C++, which require re-compilation for every hardware platform you execute the code on.

General info is given about conditional statements and the "if-then-else" statement is described here. An example included

In this video, we will talk about the ternary operator which we can use instead of the if-else satements.

Java:

Object-oriented programming (OOP) is a computer programming paradigm where a software application is developed by modeling real world objects into software modules called classes. Consider a simple point of sale system that keeps record of products purchased from whole-sale dealers and the products sold to the customer. An object-oriented language would implement these requirements by creating a Product class, a Customer class, a Dealer class and an Order class. All of these classes would interact together to deliver the required functionality where each class would be concerned with storing its own data and performing its own functions. This is the basic idea of object-oriented programming or also called oop.

Inheritance allow you to define classes in parent-child relationship. This is one of the fundamental bases of object-oriented concept.

In this video, we will talk about the Sealed class in Java programming language.

Most programmers will choose to learn the object oriented programming paradigm in a specific language. That’s why Udemy features a host of top-rated OOP courses tailored for specific languages, like Java, C#, and Python

Method overrriding allows you to customize parent class methods by yourself. Here, it will be explained.

java programming, learn core java and java improve skills; You can make a varible unalterable using "Final" keyword. Here, it is explained with an example.

java and java programming; Abstract Classes allow you to determine a concept with some restrictions on a software team. So, Each developer can customize a class by self with some base restrictions. Here, you will learn Abstract Class with an example.

The main reason why it’s the best certification, is, unlike most other certifications for Java, the Oracle certification is both well known and universally accepted by employers all over the world. The exam is challenging. You also must bring an ID with you to the exam, so you cannot get anyone to take it for you. Certification is really valuable for both the certification holder and for future employers. There are few, if any, other certification programs so universally accepted as Oracle’s Java certification.

Interface is similar to Abstract Class. There are some differences between them. One of them is that Interface have not certain restrictions. Here, you will learn Interface with example.

Polymorphism basically means that parent classes can create as self or derivative child. It is explained and shown through an example.

As a programming practise, In Object Oriented Concept (oop) you don't reach an objects variable directly. Instead, you use methods to reach variables. It is explained and shown through an example.

In this video, we will talk about the Anonymous classes in Java.

In this video, we will talk about the record keyword, and record class.

In this video, we will talk about the "var" keyword.
