Java is a famous programming language that is high-level, robust, object-oriented, and secure. Java was developed by Sun Microsystems in 1995 and owned by Oracle. Today, more than 3+ billion devices run on Java across the globe. ‘Core Java’, is the term used by Sun Microsystem to refer to the Java to standard edition J2SE. It’s the parent of all other Java editions and is used on-site internet. It has wide usage around the globe. Android that runs on Java is a very fast and secure scripting language. It is used for mobile applications like Android apps, desktop applications, web applications, Web servers and application servers, gaming, database connection, and more.
What Is Java Used For?
Java works on different platforms like Windows, Mac, Linux, Raspberry Pi, etc. It is easy-to-learning, and simple language to use. It’s an open-source and free language. Java is a secure, fast, and powerful language. It has huge community support wherein billions of developers discuss ideas and solutions. Java is an object-oriented language that gives a clear structure to programs and allows code to be reused, and saves costs. As Java is close to C++ and C#, it makes it quite easy for programmers to switch to JAVA or vice versa.
What is Core Java?
Core Java defines JAVA that will cover the basic concepts of Java Programming language. Java is quite popular and widely used programming language; the beginners will start the journey with Core JAVA and then later move to advanced JAVA. Core JAVA refers to the collection of libraries rather than just the programming languages. It’s the pure form of Java used for the development of general desktop apps. Simply speaking, it’s like a subset of JAVA SE technologies that will consist of both general-purpose APIs and special-purpose APIs. It offers the core Java functionality with a deep knowledge of the java certification.
Core JAVA is a part of Java that stands for J2SE and it contains all the basics of Java including some principles and package details. It’s a stand-alone Java app that will cover everything from OOP concepts to special operators, from data types to wrapper classes, from the Linked list to the Array list, and from the queue to exception handling.
The market has three computing platforms based on the Java programming language, including the Java SE. And it’s the most widely popular used platform based on the OOP concepts and is commonly used for portable desktop development applications. The general purpose API’s – Java programming consists of development tools, a virtual machine, and other class libraries. It includes the JAVA virtual machine specifics.
The JAVA programming language has the following editions that it will support:
JAVA Standard Edition (JAVA SE)
The Java SE is a computing-based platform and is used to develop desktop or window-based applications. Core Java is part of JAVA SE wherein the developers will develop desk-top based applications by using the basic JAVA concepts. JDK (Java Development Kit) is quite familiar with Java SE implementation.
Java Enterprise Edition (JAVA EE)
Java EE is also known as Java 2 Platform or J2EE. It’s the enterprise platform where the developer will develop applications on the servers of the enterprises. This edition is mostly used in development.
Java Micro Edition (Java ME)
Mobile phone applications can be developed by Java Micro edition. Without Java ME it's difficult to design an application. It’s clear that Core Java is the part of Java SE & Java SE stands to be the foundation for all sorts of Java editions
Concepts Covered in Core JAVA
The following concepts are the basic concepts that a beginner should go through:
Overloading & Overriding
Inheritance with Interface and Abstract Class
Swings and Applets
JDBC (Java Database Connectivity)
Spring (MVC, Core, JDBC, ORM, AOP)
Hibernate ORM framework
Web Services (SOAP & REST)
Key Difference between Java and Core Java
Java language is a general-purpose programming language based on the concepts of high-level Object-oriented programming languages. It derives most of the syntax from C and C++
Core Java is just a part of Java being used for the development of portable code for both desktop applications and server environments.
Java supports cross-platform compatibility and is designed to have lesser implementation dependencies compared to other programming languages.
Core Java is a computing platform used to develop Java applications for desktops and servers.
Java language is a robust & secure platform that makes an ideal choice for the development of application software for a wide variety of platforms like mobile phones, websites, embedded systems, servers, and more.
Core Java means Java Standard Edition (Java SE) which is the basic foundation of the Java Platform. It is used for the development of enterprise-level applications for both desktops and servers.
Java is the basic level programming language for beginners who want to learn the basics of Java Programming and gain some knowledge on Java SE.
Core Java will teach all the fundamentals of Java applications and more such as OOP concepts, Multithreading, Generics, string handling, etc.
Java comes with packages like Java, Lang, awt, Javax
Core Java has a single package known as Java.lang.
To learn Java, you require only basics and can be learned by the beginners quite easily
Core Java includes learning concepts of object-oriented programming, multi-threading, polymorphism, and others.
When we compare Java and Core Java, there is not much difference between them since core Java is a part of Java. The only key difference we would find is core Java has in-depth detailing of java and also combines a few other programs.
Java started as a simple language for the internet but later it turned into a cross-platform language developed ever before. It’s easy to operate and accessible Java is used worldwide. Core Java is called the standard Java edition and all the other Java editions came from this.
Today, nearly every device runs on Java language, and it's used in app development. Java is also used in the development of various applets and it is neutral and portable. Java, core Java and other editions are capable of executing the high-performance apps. The automatic garbage collector is used by Java to manage the object life cycle memory.
Java language also helps in designing servlets used for web development. Core Java has applications in Java and in other editions, and one java class could be extended to another class therefore it's termed an inheritance of java.
Java has evolved from a humble beginners’ language to holding a powerful share in today’s digital world, by offering a reliable platform upon which many services and applications are built. New cutting-edge products & digital services designed for the future rely heavily on Java and its editions.
Java is Just Fantastic!
Hope you know got a complete idea of what is Java, what is Core Java, and the key differences between Java vs core java
