Core Java Syllabus: Concepts, Modules, and Types of Frameworks

Java is among the top computer languages used for web, mobile, desktop applications, etc. It is a programming language based on the concept of Object-Oriented Programming Systems (OOPS). Programming enthusiasts can learn Java to upscale their skills and knowledge. After the entire Java Web application directory structure. Let’s explore what is included in the advanced, framework and core java syllabus and curriculum. 

What is Core Java?

The term “core” refers to the fundamental notion of anything, while the phrase “Core Java” refers to the fundamental concept of the Java programming language. We are all aware that Java is one of the most well-known and frequently used programming languages, and that a novice should begin with Core Java and work their way up to Advance Java. Java programming language is a general-purpose programming language based on the object-oriented programming (OOPs) paradigm. Java’s ocean is too deep to learn, i.e., the more you study, the deeper it becomes. Java is a powerful and platform-independent programming language. Java follows the WORA philosophy, which stands for Write Once, Run Anywhere. The programming language is straightforward and simple to grasp. However, it is important to note that Core Java is not the same as Java. Although Java is self-contained, it is normal for newcomers to start with the fundamentals of the language. In reality, there are several editions of Java, with Core Java being one of them.

Java Editions

The Java Programming Language supports the following declared editions:

Java SE (Java Standard Edition)	Java SE is a computer platform that may be used to create desktop or Windows-based applications. Thus, core Java is a portion of Java SE in which developers create desktop-based programs utilizing Java’s fundamental ideas, with JDK (Java Development Kit) being a well-known Java SE implementation.
Java EE (Java Enterprise Edition)	Also known as J2EE or Java 2 Platform. It is the enterprise platform on which a developer creates applications for servers, i.e. enterprise development. This is the edition for web development.
Java ME (Java Micro Edition)	It is the tiny version that is used for mobile phone application development. As a result, Java ME is required for the creation of mobile apps. As a result, Core Java is clearly a part of Java SE, and Java SE serves as the foundation for all subsequent Java versions.

Types of Java Courses

Java is categorized into 3 types with very minor differentiation among them.

• Core Java (Java SE & JDBC)
• Advanced Java (Servlets and JSP)
• Different types of FrameWorks (Spring & Hibernate etc.)

Concepts Covered in Core Java

The following are some of the most important Java fundamental topics for a novice to learn:

Java Fundamentals	Packages
OOPs Concepts	Collections
Overloading & Overriding	Multithreading
Inheritance with Interface and Abstract Class	Swings
Exception Handling	Applets JDBC (Basic Database Connections)

Different Types of Core Java Frameworks

This section will show you some of the most popular Java frameworks of 2020. While there are more than just 10 such frameworks, the ones listed and discussed stick out because of their significant features and ease of use.

Spring

Spring is a core part of the java syllabus and is a very lightweight implementation of the framework, usable for pretty much any type of Java project. It’s a modular framework that you could use for any level or layer of a project. What makes it stick out is the fact that you can use it to work on not just one layer of a project but also the entire scope.

Hibernate

Hibernate is an object-relational mapping (ORM) framework that makes common data-handling mismatch cases a thing of the past. If you’re always working with relational databases, the Hibernate ORM framework could easily become your staple.

The framework comes stock with data handling muscle that bridges paradigm differences. Companies like IBM and Dell have used the Hibernate framework for their web applications.

JSF (JavaServer Faces)

It’s often a huge task for back-end developers to get the front side of complex applications right. This is where JSF comes in handy.

The Oracle-built, stable framework comes with a component-based MVC environment to create beautiful “faces” for Java applications. It’s packed to the brim with libraries that allow developers to experiment with the front end—without introducing other frameworks for that part.

GWT (Google Web Toolkit)

As can be expected from a Google product, GWT is open source. The main reason many developers’ work starts with GWT is that it’s easy to make beautiful UIs with little knowledge of front-end scripting languages. It basically turns Java code into browser-friendly packages.

Web apps such as Blogger, Google Analytics, and Google Adsense are all built using Java with the GWT framework. It’s fully featured and supported by a large group of developers dedicated to the framework, making it perfect for scale-sensitive application development.

Struts (The Later Version)

Strut is also part of the core java syllabus and is an Apache-run enterprise-level framework perfect for web developers. It’s feature-rich and comes in two versions: Struts 1 and 2. The most widely used is Struts 2, which basically extends the first version with everything that comes with OpenSymphony web framework tools. That means you get to apply new technologies such as Ruby and new JavaScript frameworks to extend your Java applications’ functionality.
