What is the Difference Between Core Java and Advanced Java

The main difference between Core Java and Advanced Java is that the Core Java is used to build general applications while the Advanced Java is used to build enterprise level applications.

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.

What is Core Java

Core Java mainly focuses on building general applications. Java Standard Edition (J2SE) is categorized as Core Java. Core Java mainly covers object-oriented programming concepts. The main OOP pillars are encapsulation, inheritance, abstraction and polymorphism. They are as follows.

Encapsulation – Combines data and methods to a single unit

Inheritance – Allows using an already created class without writing the code from the beginning, improving the code reusability

Polymorphism – Allows writing code in a way that an object can behave in multiple ways

Abstraction – Allows writing the code in a way that hides the implementation details to reduce complexity.

Core Java helps to implement the above concepts when developing software.

In addition, Core Java covers concepts such as swing, AWT, threading and collections. Swing and AWT help to build powerful Graphical User Interfaces (GUIs).  Furthermore, threading allows executing multiple processes simultaneously while collections allow manipulating a group of objects. Overall, Core Java covers all the fundamental concepts of Java programming language.

What is Advanced Java

Advanced Java is the level ahead of Core Java, and covers more advanced concepts such as web technologies, and database accessing. Java Enterprise Edition (J2EE) is categorized as Advanced Java.

Advanced Java covers a number of topics. JDBC stands for Java Database Connectivity. It is a standard Java API to build independent connectivity between the Java language based application and databases such as MySQL, MSSQL, and, Oracle. Additionally, Servlets and JSP allow developing dynamic web applications. EJB provide distributed and highly transactional features to build enterprise applications. Furthermore, Java web services help to build SOAP and RESTful web services. They provide a common platform for the applications to communicate with each other.

Relationship Between Core Java and Advanced Java

• Advanced Java depends on Core Java. As a result, it is not possible to develop applications using Advanced Java without Core Java knowledge.

Difference Between Core Java and Advanced Java

Definition

Core Java is the category of Java that covers the fundamental concepts of Java programming language to develop general applications. Advanced Java is the category of Java that covers the advanced concepts to build enterprise applications using Java programming language. Hence, this explains the main difference between Core Java and Advanced Java.

Java Version

Java Standard Edition (J2SE) comes under Core Java while Java Enterprise Edition (J2EE) omes under Advanced Java.

Topics or Areas

OOP, data types, operators, exception handling, threading, swing, and collections are some topics in Core Java. In contrast, database connectivity, web services, Servlets, JSP, EJB, etc. are some topics in Advanced Java.

Architecture

Furthermore, core Java uses single tier architecture. In contrast, Advanced Java uses two-tier architecture. e.g.- client, server architecture. This is a major difference between Core Java and Advanced Java.

Applications

Another ifference between Core Java and Advanced Java is that Core Java helps to build general applications while advanced Java helps to build enterprise level applications. e.g., web applications, etc.

Conclusion

In brief, Core Java and Advanced Java are two types of Java language. The main difference between Core Java and Advanced Java is that Core Java is used to build general applications while Advanced Java is used to build enterprise level applications.
