What is Java?
Java is hypothetically everywhere, thanks to its readability and simplicity. From mobile applications to sites, game consoles, datacenters, from mobile phones to the Internet, Java is everywhere. Millions of devices around the world use Java as a primary programming language. Even all native Android applications are integrated with Java and several companies use Java as a server-side scripting language for backend development. Many applications and websites require you to install Java because it is fast and secure. What began as simply an Internet language has become one of the most versatile multiplatform programming languages already developed. The best part runs literally on any device without the need for recompilation, hence the slogan “Write once, run anywhere”.
In technical terms, it is a high-level programming language that is object-oriented, class-based, and specially designed to have fewer implementation dependencies than the previous languages. It is influenced by the V language and much of its syntax is derived from C and C ++. Java applications are usually compiled for the bytecode and a class file that contains a Java bytecode can run on any platform that runs a Java virtual machine (JVM), regardless of the architecture of the computer. It is completely independent of the platform, which means that it can execute any code compiled on any platform. The abundance of information and its growing popularity is the reason why programmers and developers prefer Java over other programming languages for the development of applications.
What is Core Java?
It is a general term used by Sun Microsystems to describe the standard version of Java (JSE). It is the most basic version of Java, which defines the basis for all other editions of Java, as well as a set of related technologies, such as CORBA, Java VM, etc. Core Java refers to a collection of libraries, and not just the programming language. It is the purest form of Java used mainly for the development of general desktop applications. Simply speaking, it refers to the subset of Java SE technologies, which consists of general-purpose APIs and special-purpose APIs. It provides the main functionality of Java with the deep knowledge of the Java language itself.
Core Java is just a part of Java, which means J2SE, which contains all the basic Java concepts, including some principles and package details. It is an independent Java application that ranges from OOP concepts to special operators, from data types to container classes, from list of links to list of matrices and queue of manipulation of exceptions. There are three computing platforms based on the Java programming language, including Java SE. It is still the most widely used platform based on the OOP concept and is commonly used for the development of portable desktop applications. In addition to the general purpose APIs, it consists of development tools, a virtual machine and other class libraries. It also includes the Java Virtual Machine specification.
Difference Between Java and Core Java
Java is a high-level general-purpose programming language based on the concepts of object-oriented programming (OOP) that derived much of the C and C ++ syntax. It was specially designed to have fewer implementation dependencies compared to previous versions. It is a computational platform for application software development developed by Sun Microsystems, which was later acquired by technology giant Oracle Corporation. The main Java is never really defined anywhere and is just a term used by Sun Microsystems to better describe the Java Standard Edition (Java SE). This is the most basic and robust version of Java, which consists of a wide variety of APIs for general and special purposes. The reason is called the standard edition because it gave rise to all the other Java editions.
Basic concepts of Java and Java Core
Java is a general-purpose programming language based on the concepts of the high-level object-oriented programming language that derives most of the C and C ++ syntax. Core Java, on the other hand, is just a part of Java used for the development of portable code for desktop applications and server environments.
Platform of Java and Core Java
Java is a programming language that supports cross-platform compatibility and is designed to have fewer implementation dependencies compared to other programming languages. Core Java is a computing platform used to develop Java applications for desktops and servers.

Application of Java and Java Core
Java is robust and secure and platform independent, which makes it an ideal choice for the development of application software for a wide variety of platforms, including mobile phones, sites, embedded systems, servers and much more. Core Java refers to Java Standard Edition (Java SE), which is the basic basis of the Java platform and is used for the development of enterprise level applications for desktops and servers.
Java is the entry level programming language for beginners who want to learn the basics of the Java programming language and some knowledge of Java SE. Core Java teaches all the fundamentals of Java applications and more includes concepts of OOP, multi-threading, exception handling, polymorphism, etc.

Summary of Java vs. Java Core
Hypothetically, there is no difference between the two. Everything is only Java. Both terms are practically the same, considering that the Java Core is only a part of Java that means Java Standard Edition, as well as a set of related technologies. Java is a high-level class-based programming language developed by Sun Microsystems, which was subsequently acquired by Oracle Corporation. While Java is used for the development of applets and applications, Core Java is mainly used to design applications for desktop and server environments. Core Java is the most basic and purest form of Java that defines the basis for other editions of the programming language.
