  • Known as Core Java, it forms the foundation of the Java programming language.
  • Focuses on essential libraries and components for general-purpose development.
  • Emphasizes object-oriented programming (OOP) principles.
  • Primarily used for crafting desktop or Windows-based applications.
  • The Java Development Kit (JDK) is a well-known implementation of Java Standard Edition (Java SE).

(2) Java Enterprise Edition (EE):

  • Java EE (also known as Java 2 platform or J2EE) is the enterprise platform designed for server-based application development.
  • Strongly emphasizes on large-scale enterprise applications.
  • Provides additional features like JavaServer Faces (JSF), Enterprise JavaBeans (EJB), and more.
  • Suitable for developing robust, scalable, and distributed server-side applications, making it a preferred choice for web development.

(3) Java Micro Edition (ME):

  • Designed for developing mobile phone applications.
  • Offers a streamlined framework for creating applications designed for mobile devices.
  • Ideal for developing applications for feature phones and other embedded systems.

(4) JavaFX:

  • Designed for creating rich internet applications (RIAs).
  • Provides a set of graphics and media packages for building visually appealing user interfaces.
  • Suited for developing modern and interactive applications.

Difference between Core Java and Advanced Java

The main differences between Core Java and Advanced Java are as:

(a) Syntax and programming complexity

Core Java has a simpler syntax and is easier to learn compared to Advanced Java. Advanced Java requires a higher level of programming expertise and understanding of complex programming concepts.

(b) Libraries and frameworks

Core Java provides a basic set of libraries and tools, while Advanced Java provides a wide range of libraries, tools, and frameworks that simplify the development of complex applications.

(c) Application and system requirements

Core Java applications have lower system requirements compared to Advanced Java applications. Advanced Java applications require more advanced hardware and software configurations to run efficiently.

(d) Skill level and job opportunities

Core Java developers are more common and easier to find compared to Advanced Java developers. Advanced Java developers require more advanced skills and expertise and therefore have higher job opportunities and better salaries.
