Components Of Java Programming Language :-
There are three components in Java programming language, which are as follows:

Java Runtime Environment (JRE)
Java Development Kit (JDK)
Java Virtual Machine (JVM)
JRE is a runtime environment. It is the implementation of JVM. JRE consists of core classes, java virtual machine and other supporting files. It does not contain any development tools. JRE is used for executing the java programs. Java course in Pune

JDK is development environment. It contains java compiler, java virtual machine, core classes and debugging tool. JDK is used for developing java applications and applets.

Java is a platform independent language. The java code can be run on any platform. JVM is platform dependent. JVM is a part of JRE and JDK. JRE and JDK are platform independent and can be run on any platform.

1. Object-Oriented: In java, everything is an object. There are no primitive data types like int, float, char, double, byte, etc.
2. Platform Independent: Java programs can run on any platform that has a JVM (Java Virtual Machine) installed. \
3. Simple: Java is easy to learn and its syntax is simple, clean, and easy to understand. Java course in Pune
4. Secure: With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.
5. Portability: Being architecture-neutral and having no implementation dependent aspects of the specification, makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.
6. Robust: Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.
