Know the Importance of Core JAVA and Its Uses

Core Java refers to a computing platform, more commonly known as the Java Platform Standard Edition (SE). It is one of the most widely used platforms of the Java programming language. It is most generally used in the development of portable applications for desktop and server environments. It consists of all the basics of Java language, variables, and primitive data types, Arrays, Streams, Strings Java Database Connectivity (JDBC) etc.

The term also refers to a set of related technologies like Java VM, CORBA, etc. An important thing to note is that Core Java is not a programming language in of itself, but rather a set of libraries and general purpose APIs (buffer management, object serialization and device input/output). Hence, the underlying way of writing Java doesn’t change, regardless of the libraries one is using. 

Core Java comes with a rich set of APIs which include the Java Language Specification and the Java Virtual Machine Specification. The APIs also come with a set of security functions, like digital signing, setting up access control and secure network communication. Another important feature of the APIs, which allows the program to be used in any language, is Localization.

A few of the many applications of core Java are:

  • It is highly useful for creating web based applications. A lot of services are created using Spring MVC, Struts 2.0 and similar frameworks. Many of the government, healthcare, education, defence, insurance, etc. e-commerce applications are developed in Java.
  • Huge global investment banks like Goldman Sachs, Citigroup, Standard Chartered and others, use Java for writing office electronic trading systems, settlement and confirmation systems, etc.
  • A bunch of useful software tools are written and developed in Java, like Netbeans IDE, InetelliJ, Eclipse, etc. They are also some of the most used desktop applications.
  • It is also capable of being used for ‘embedded devices’ like smart card sensors, as only 130 KB is required to use Java technology.
  • Because of Java SE’s safety and portability, it is also used for high performance trading systems as well as scientific applications.

One should get trained in core JAVA from trusted JAVA training institute like Coder Technologies.
