## OBJECT-ORIENTED PROGRAMMING LANGUAGE ## OBJECT-ORIENTED PROGRAMMING LANGUAGE
JAVA is one of the OBJECT ORIENTED PROGRAMMING LANGUAGES, unlike C and FORTAN which are procedural languages. The OBJECT ORIENTED concept of programming makes it much more efficient than procedural languages. Basically, object orientation breaks the program into parts, which is decided by the programmer. Then the complete program is stored in the permanent memory and when it is executed only that part is brought to dynamic memory which is called by the programmer. Each such part is called a `class` and when it is called in the dynamic memory it is called an `object`.

Download the latest Java binaries from the <a href='http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html' target='_blank' rel='nofollow'>official website</a>. Here you may be faced with a question: which one should I download, JDK or JRE? JRE stands for Java Runtime Environment, which is the platform dependent Java Virtual Machine to run Java codes. JDK stands for Java Development Kit, which consists of most of the development tools, most importantly the compiler `javac`, and also the JRE. So, for an average user JRE would be sufficient, but since we will be developing with Java, we should download the JDK.
