What is java programming language?
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Features of Java Language
There is given many features of java. They are also known as java buzzwords. The Java Features given below are simple and easy to understand.
- Platform independent
- Architecture neutral
- High Performance
Core Java vs Advanced Java
Here you will see a feature-wise comparison of core Java vs advanced Java –
1. Definition of Java Programming
What is Core Java? – Core Java is the fundamental form of Java. We use it in all Java platforms and technologies. Without going through core Java, it is impossible to advance to advanced Java.
What is Advanced Java? – Unlike core Java, advanced Java is a specialization of the core Java in some particular domain, such as database handling, networking, and the web.
2. Applications Developed in Java Programming
Core Java covers the fundamental concepts of Java programming language for developing general applications. Advanced Java, on the other hand, covers advanced topics pertaining to Java programming language that helps in building enterprise-level applications.
3. Architecture of Java Language
The core Java makes use of single-tier architecture. On the flip side, advanced Java uses instances of two-tier architecture, such as client-server architecture.
In a one-tier architecture, the data stores in the local system or a shared drive. It has all the layers, such as Business, Data Access, and Presentation.
An architecture where the presentation layer or the interface layer runs on a client while the data layer or the data structure stores on a server called as a two-tier architecture.
4. Java Packages
All core Java packages have a naming convention of java.lang.somepackage. On the contrary, packages for advance Java follows javax.servlet.somepackage.
5. Knowledge of Java Language
Typically, there are three levels of Java knowledge, namely Java, core Java, and advanced Java. Hence, both core Java and advanced Java differ in terms of knowledge.
Java – The basic level. This is where one learns how to write a Hello World program in Java and create basic Java programs.
Core Java – It is the level in Java proficiency required as a minimum for getting a job.
At this level, one needs to have an expertise in Java Collections, Java Exception Handling, Java Multi-threading, OOPS, Polymorphism, et cetera
Advanced Java – In addition to knowledge of core Java, one needs to have a sound understanding of various related packages and advanced concepts, such as JSON parsing, REST service creation, and XML handling
