What are the basics of Java?
Java is a programming language which is platform independent and runs on Linux, Windows, Mac and other operating system. It is designed to be used with high-level abstractions and methods that have a lot of functionality. It has a wide range of functional programming languages and multiple languages for different types of objects (programs, collections, and structures).
Java is an open-source language. In order to make it more accessible to people who don't understand these technicalities, Java is available for a free download from the oracle.com or from https://openjdk.java.net/.
Read on to find out about the basics and learn about Java and its components. Tutorials here will teach you the basics of Java. If you've ever done anything in programming before and are still confused then you can learn a lot from our tutorials.
The Basic Concepts of Java
Java programs are written in Java programming language as text file and saved at .java file. This file is then compiled using the Java compiler. Java compiler converts Java code into byte code which is run by host Java Virtual machine on the computer.
Java is platform independent and you can run compiled Java code on all operating systems having JVM installed on to it.
JRE and JDK are the main packages that every Java application uses. JNI is a Java extension to this package. JNIs are compiled down to run on Java Virtual Machines and run the VM. JAVA, which stands for Java Development Kit, is the software that all developers are using to develop programs.
The Java Virtual Machine (JVM) is an execution environment for the Java language of which Java applications are developed. The JVM provides an environment that allows you to create, compile, package, and link Java programs. The JVM includes such features as garbage collection, multithreading support, access to the JRE runtime through virtual machines.
