7 Amazing Features of Java Every Programmer Must Know
                     7 Amazing Features of 
Java Every Programmer 
Must Know
The primary objective of Java programming language creation 
was to make it portable, simple and secure programming 
language. Apart from this, there are also some excellent 
features which play an important role in the popularity of this 
language.
Java is a compiled and 
interpreted language
Unlike many other programming languages including 
C and C++, when Java is compiled, it is not compiled 
into platform specific machine, rather into platform-
independent byte code. This byte code is distributed 
over the web and interpreted by the Virtual Machine 
(JVM) on whichever platform it is being run on. Java Compiled & Interpreted
byte code is translated on the fly to native machine 
instructions and is not stored anywhere.
Java solves the problem of platform-independence by 
using byte code. The Java compiler does not produce 
native executable code for a particular machine like a 
C compiler does. Instead it produces a special format 
called byte code. Java byte code is written byte by 
Platform Independent & byte, pair of hexadecimal numbers represents 1 byte
Portable Language
Write Once and Run Everywhere 
!
Being architecture-neutral and having no 
implementation dependent aspects of the 
specification makes Java portable. The compiler in 
Java is written in ANSI C with a clean portability 
boundary, which is a POSIX subset.

Architecture-neutral
Software that is designed without 
regard to the target platform
Java compiler generates an architecture-
neutral object file format, which makes the 
compiled code executable on many 
processors, with the presence of Java 
runtime system.
JAVA  BUZZWORDS
Java is Object Oriented 
Programming Language
Java is purely an object oriented 
language due to the absence of global 
scope, Everything in java is an object, 
all the program codes and data resides 
within classes and objects. It comes 
with an extensive set of classes, 
arranged in packages, object model in 
java in sample and easy to extend.
Java is Robust & Distributed Language
Java is easy to learn for programmers. Most people pick 
Java as their first programming language. Moreover, the 
popularity of Java still persists in the industry.
Robust Distributed
Java makes an effort to eliminate error Java is also a distributed language. 
prone codes by emphasizing mainly on Programs can be designed to run on 
compile time error checking and computer networks. Java has a special 
runtime checking. But the main areas 
class library for communicating using 
which Java improved were Memory 
Management and mishandled TCP/IP protocols. Creating network 
Exceptions by introducing automatic connections is very much easy in Java 
Garbage Collector and Exception as compared to C/C++.
Handling.
Multi-Threading
Thread is a lightweight and independent 
subprocess of a running program (i.e, 
process) that shares resources. And when 
multiple threads run simultaneously is called 
multi-threading. 
In many applications, you have seen multiple tasks 
running simultaneously, for example, Google Docs where 
while typing text, the spell check and autocorrect task 
are running. 
Server also uses multithreading to provide its services to 
multiple client requests. In Java, you can create threads 
in two ways, either by implementing the Runnable 
interface or by extending the Thread class.
