The Java Programming Environment

Java is a powerful general-purpose programming language that has been around for over 23 years now since its inception in 1996. The Java Programming environment consists of —

1. Java Language — used by programmers to write the application
2. The Java Virtual Machine (JVM) — used to execute the application
3. The Java Ecosystem — provides additional value to the developers using the programming language

What is the Java Language?

• It is a human-readable language which is generally considered easy to read and write (albeit a bit verbose at times).
• It is class-based and object-oriented in nature.
• Java is intended to be easy to learn and to teach.
• There are many different implementations of Java available, both proprietary and open source.
• The Java Language Specification (JLS) defines how a confirming Java application must behave.
