Core Java vs Advanced Java

In this article Core Java vs Advanced Java we give the differences in details for core java and advanced java like core java used for Builds the foundation of Java – object-oriented programming, basic syntax, etc..

Core Java vs Advanced Java

Core Java

Key Features:

Platform-independent: “Write Once, Run Anywhere” using the JVM.
OOP-centric: Strong emphasis on Object-Oriented Programming.
Memory Management: Automatic garbage collection.
Multithreading Support: Enables concurrent programming.
Security: Built-in security features like bytecode verification and access control.

Advanced Java

Key Features:

Client-server architecture: Build web-based, distributed applications.
Supports Enterprise Development: Used in large-scale applications like banking, CRM, ERP.
Networking and Multitier Architecture: Capable of building scalable, layered applications.
Database Interaction: Through JDBC for persistent storage.

Feature / Aspect	Core Java	Advanced Java
Definition	Core Java refers to the fundamental part of the Java programming language, used for general-purpose programming.	Advanced Java refers to specialized APIs and tools used for developing web-based, network-centric, and enterprise applications.
Purpose	Builds the foundation of Java – object-oriented programming, basic syntax, etc.	Extends Core Java to create web, distributed, and enterprise-level applications.
Main Focus	Desktop applications and console-based apps.	Web-based applications and client-server applications.
Key Topics	– OOPs (Inheritance, Polymorphism, etc.) – Data Types & Variables – Control Statements – Arrays – Exception Handling – Threads – Collections – File I/O	– JDBC (Database Connectivity) – Servlets – JSP (JavaServer Pages) – JavaBeans – Networking (Socket Programming) – RMI (Remote Method Invocation) – JavaMail – MVC Architecture
Scope	Basic programming and standalone application development.	Enterprise and web application development.
APIs Used	java.lang, java.io, java.util, java.math, java.net, etc.	javax.servlet, javax.swing, java.sql, javax.mail, etc.
User Interface	Mostly console-based or basic GUI (Swing, AWT).	Web UI using HTML, JSP, Servlets, JavaScript, etc.
Database Access	Usually not emphasized.	JDBC used for database interaction.
Deployment Environment	Local system (desktop)	Web/Application servers (like Apache Tomcat, GlassFish)
