Java could also be a programming language and a computing platform for application development. it's class-based, object-oriented, and designed to possess as few implementation dependencies as possible. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle) and released in 1995 as a core component of Sun Microsystems' Java platform. it's almost like C and C++ but tons easier. you'll combine Java with plenty of technologies like Spring, node js, Android, Hadoop, J2EE, etc… to make robust, scalable, portable and distributed full-fledged applications. Java also promotes continuous integration and testing using tools like Selenium.
Java applications are typically compiled to bytecode which can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.Objectives:
Java is one of the most popular programming languages used to create Web applications and platforms. Java language developed by company "SUN micro systems" and created by "James Gosling".
Java is the high level programming language used to create Web applications and enterprise applications. It was designed for flexibility, allowing developers to write code that would run on any machine, regardless of architecture or platform.
Swing is a high level Java GUI tool set launched by Sun Microsystems. It is used to develop Visual customer connections with Java. Java Swing is the GUI toolkit for Java programming language.
Java 2 Platform Enterprise Edition. J2EE is a platform independent, The J2EE platform consists of a set of services, APIs and protocols that provide the functionality for developing multitiered, Web-based applications.
