Java is a general-purpose high-level programming language that helps to build a variety of applications. Java is popular as it provides platform as it provides various features such as independency, security, multithread support.

There are two types of Java as Core Java and Advanced Java. Core Java covers the fundamental concepts in the Java programming language. On the other hand, Advanced Java is the next level after Core Java. To know in detail about these two technologies you learn online JAVA training courses.In this post, let’s discuss the main differences between Java and advanced Java:


What is Core Java? — Core Java is the fundamental form of Java. We use it in all Java platforms and technologies. Without going through core Java, it is impossible to move to advance Java.

What is Advanced Java? — Unlike core Java, advanced Java is a specialization of the core Java in some particular domain, such as database handling, networking, and the web.


Core Java covers the fundamental concepts of Java programming language for developing general applications. Advanced Java, on the other hand, covers advanced topics pertaining to Java programming language that helps in building enterprise-level applications.

Applications developed using core Java are typically standalone applications meant to be either cross-platform or platform-specific. Simply, core Java helps in building general applications, such as a student attendance management system, EMI calculator, or the classic snake game.

On the contrary, applications developed using advanced Java are those that enterprises use or are at an enterprise-level. This includes apps that run on servers i.e. web applications.


The core Java makes use of single-tier architecture. On the flip side, advanced Java uses instances of two-tier architecture, such as client-server architecture.

In a one-tier architecture, the data stores in the local system or a shared drive. It has all the layers, such as Business, Data Access, and Presentation. An architecture where the presentation layer or the interface layer runs on a client while the data layer or the data structure stores on a server called as a two-tier architecture. JAVA online training program will help you in learning more about JAVA architecture.


All core Java packages have a naming convention of java.lang.somepackage. On the contrary, packages for advance Java follow javax.servlet.somepackage.


Typically, there are three levels of Java knowledge, namely Java, core Java, and advanced Java. Hence, both core Java and advanced Java differs in terms of knowledge.

· Java — The basic level. This is where one learns how to write a Hello World program in Java and create basic Java programs.

· Core Java — It is the level in Java proficiency required as a minimum for getting a job. At this level, one needs to have an expertise in Java Collections, Java Exception Handling, Java Multi-threading, OOPS, Polymorphism etc.

· Advanced Java — In addition to knowledge of core Java, one needs to have a sound understanding of various related packages and advanced concepts, such as JSON parsing, REST service creation, and XML handling.


While the Java Standard Edition (Java SE) comes under core Java, advanced Java encompasses the Java Enterprise Edition (Java EE).


Core Java covers basic concepts and topics pertaining to the Java programming language. Is Java For Mechanical Engineers.This includes data types, exception handling, operators, and threading.

On the other hand, advanced Java entails complex topics and concepts that require non-Java technologies. Some notable examples are database connectivity, EJB, JSP, servlets, and web services.
