Difference Between Java and Core Java

Java is a programming language known for its simplicity, object-oriented nature, and platform independence. It consists of three major editions: Java Standard Edition (JSE), Java Enterprise Edition (JEE), and Java Micro Edition (JME). On the other hand, Core Java specifically refers to Java Standard Edition (JSE), which is the base and most essential edition of Java.

1. Scope and Application:

Java: Java has a broad scope and application range. It is used for developing applets, desktop applications, web applications, mobile applications, and enterprise-level systems. It encompasses JSE, JEE, and JME, making it suitable for various platforms and devices.

Core Java: Core Java focuses primarily on developing desktop and server-based applications. It includes the foundational concepts and features of the Java language without the additional components and APIs provided by JEE and JME.

2. Editions:

Java: Java includes JSE, JEE, and JME. JSE provides the core functionality of Java; JEE is used for enterprise-level applications, and JME is designed for resource-constrained devices.

Core Java: Core Java specifically refers to JSE, which is the base and essential edition of Java. It covers the foundational concepts and features of the Java language.

3. Development Focus:

Java: Java has a broader development focus and is used for a wide range of applications, including desktop applications, web development, server-side applications, enterprise systems, mobile applications, and embedded systems.

Core Java: Core Java focuses on developing desktop and server-based applications. It provides the necessary tools and features for building standalone applications and server-side solutions.

4. Component and API Coverage:

Java: Java consists of a comprehensive set of additives and APIs furnished by JSE, JEE, and JME. It gives a wealthy ecosystem of libraries, frameworks, and gear for unique application domains, inclusive of JavaFX for graphical user interface development, JDBC for database connectivity, and JAX-RS for RESTful net services.

Core Java: Core Java covers the essential components and APIs provided by JSE. It includes functionality for tasks like input/output (I/O) operations, networking, file handling, and string manipulation. Core Java forms the foundation for Java development without the additional specialized APIs and components of JEE and JME.

5. Target Platforms:

Java: Java is platform-independent, which means Java programs can run on any platform with a Java Virtual Machine (JVM) installed. It supports various working structures, which include Windows, macOS, Linux, and greater. It can also goal one-of-a-kind devices and architectures, consisting of computing devices, computers, servers, mobile gadgets, and embedded systems.

Core Java: Core Java applications are basically evolved for computing devices and server-based systems. They are not mainly designed for embedded structures or cellular gadgets.

6. Learning Focus:

Java: Learning Java involves understanding the language syntax, object-oriented programming principles, libraries, frameworks, and APIs provided by JSE, JEE, and JME. It requires knowledge of various application domains and technologies.

Core Java: Learning Core Java focuses on mastering the foundational concepts of the Java language, such as variables, data types, control structures, classes, objects, inheritance, polymorphism, and encapsulation. It provides a solid foundation for Java development and serves as a prerequisite for learning advanced Java technologies and frameworks.

7. Community and Support:

Java: Java has a large and active community that contributes to its continuous improvement and evolution. The Java community includes developers, experts, and open-source organizations. It benefits from continuous updates, enhancements, and contributions from industry experts.

Core Java: Core Java benefits from the overall Java community but does not have a dedicated community-driven focus. It leverages the resources, tutorials, and support available within the broader Java community.

8. Platform Features:

Java: Java offers a huge range of platform capabilities, along with automatic memory management (garbage collection), exception handling, multithreading, networking abilities, safety features, and aid for numerous data formats (XML, JSON).

Core Java: Core Java includes the foundational platform capabilities supplied with the aid of JSE, including garbage collection, exception handling, simple I/O operations, networking capabilities, and multithreading. It forms the basis for understanding and utilizing these features in Java applications.

9. Extensibility:

Java: Java provides extensibility through its various editions and the availability of libraries, frameworks, and APIs. Developers can leverage specialised APIs in JEE and JME to increase the capability of Java and cater to particular application necessities. The extensibility allows Java to be used in various domains, which include large information processing, device learning, Internet of Things (IoT), and more.

Core Java: Core Java, being the foundational edition, offers limited extensibility compared to the broader Java ecosystem. While developers can utilize third-party libraries and frameworks, the core focus of Core Java remains on the essential components and features of the language.

10. Deployment and Runtime Environment:

Java: Java packages require the Java Runtime Environment (JRE) or Java Development Kit (JDK) to be installed on the target device. The JRE affords the essential runtime surroundings to execute Java programs, while the JDK includes additional improvement equipment. The availability of the JRE or JDK across different platforms ensures the portability and compatibility of Java applications.

Core Java: Core Java applications, being part of JSE, also require the JRE or JDK for deployment and execution. However, since Core Java is primarily focused on desktop and server-based applications, the deployment and runtime environment considerations are more straightforward compared to Java applications targeting specialized editions like JEE or JME.

Differences Between Java and Core Java

These are the main distinctions between Core Java and Java.

Conclusion

Since Core Java is an extension of Java, we see no difference when we compare it to Java. What makes core Java different is that it has comprehensive Java documentation together with a collection of a few other apps.

Servlets, which are used in web development, are also made with Java. This is known as Java inheritance, and it is possible to extend one Java class to another in Java and other editions. Java meets all of the standards for safe, secure, and resilient use.
