Java is a high-level, general-purpose programming language that facilitates the development of numerous applications. Java is well-liked because it offers a variety of characteristics, including independence, security, and support for many threads. Core Java Or Advanced Java are the two different subtypes of Java. The Java programming language’s foundational ideas are covered in Core Java.
Beyond Core level Java is Advanced Java, on the other side. The primary distinction between Core Java & Advanced Java was that the latter is used to create enterprise-level applications while the former is used to create generic apps. Core Java is necessary for Advanced Java. As a result, Core Java expertise is required to construct apps utilising Advanced Java.
Core Java
Core Java is primarily concerned with developing generic programmes. Core Java is a category that includes Java Standard Edition (J2SE). Object-oriented programming ideas are mostly covered in core Java. The four main pillars of OOP are encapsulation, inheritance, abstractions, and polymorphism. Below is a list of them.
- Combining data and methods into a single unit is called encapsulation.
- The ability to use a class that was previously built without starting from scratch, thanks to inheritance, increases the reusability of the code.
- The ability to write software so that even an object may act in several ways is known as polymorphism.
- Abstraction reduces the complexity of the code to be reduced by writing it in a way that hides implementation specifics.
- When creating software, Core Java aids in putting the ideas above into practice.
Swing, AWT, threading, and collections are just a few topics covered in Core Java. Swing and AWT aid in developing robust Graphical User Interfaces (GUIs). Additionally, threading enables the simultaneous execution of several processes, whereas collections enable the manipulation of a collection of objects. Core Java covers all the core ideas of the Java programming language.
How does Advanced Java work?
The level above Core Java, Advanced Java, includes more complex ideas, including web technology and database access. Advanced Java includes Java Enterprise Edition (J2EE). A variety of subjects are covered in advanced Java. JDBC, or Java Database Connectivity, represents the ability to create independent communication between Java-based applications. A Standard Java API provides databases like MySQL, MSSQL, and Oracle. The development of dynamic websites is also made possible by Servlets and JSP. Enterprise applications may be built using distributed and extremely transactional characteristics. Java web services also aid in the development of SOAP or RESTful web services. They offer a unified channel for communication between the apps.
What makes Core Java different from Advanced Java?
The Java programming language’s core ideas are covered by the Core Java category, which is used to create generic applications.
- The Java programming language’s advanced principles for creating corporate applications are covered within the category of Java known as “advanced Java.”
- Java Standard Edition (J2SE) and Java Enterprise Edition (J2EE) fall under the categories of Core Java and Advanced Java, respectively.
- The subjects covered in Core Java include OOP, types of data, operations, exception handling, threads, swing, and collections. In comparison, some subjects in Advanced Java include database connection, online services, Servlets, Jsf, EJB, etc.
- Core Java also has a single-tier architecture. Advanced Java, in contrast, employs a two-tier design, such as client and server architecture. The chief difference between Core Java and Advanced Java is mentioned above.
Another distinction between Core Java as well as Advanced Java. And that is when Advanced Java supports the development of enterprise-level applications, and Core Java supports the development of generic apps. Web applications, for instance.
| Core Java | Advanced Java |
| Used Creating general-purpose applications. | To create an internet application as well as a mobile application. |
| Nobody can create powerful Java programmes without Core Java. | Advanced Java, on the other hand, solely deals with particular specialisations such as databases, DOM (web), networking, etc. |
| Some examples are data types, operators, functions, loops, handling exceptions, threading, and OOP. | It has several aspects, including database connectivity, web services, servlets, etc., and the standard Java components. |
| Because it only employs a single tier of architecture, it is referred to as a “stand alone” application. | It employs a two-tier architecture consisting of client-side and backend server components |
| Swings, sockets, Awt, the threading idea, collection objects, and classes are all covered by the fundamentals of Java programming. | Web-based applications and business applications require advanced Java. |
