Java is a general-purpose, class-based, object-oriented programming language designed for having lesser implementation dependencies. It is a computing platform for application development. Java is fast, secure, and reliable, therefore. It is widely used for developing Java applications in laptops, data centers, game consoles, scientific supercomputers, cell phones, etc. If you want to learn Core and Advanced Java Concepts , then you can consider joining CETPA Infotech Pvt Ltd, Noida.

1. 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.

2. Java is a compiled and
interpreted language
Compiled & Interpreted
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
byte code is translated on the fly to native machine
instructions and is not stored anywhere.

3. Platform Independent &
Portable Language
Write Once and Run
Everywhere !
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
byte, pair of hexadecimal numbers represents 1 byte
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.

Most famous programming languages
Java is Simple and Secure
Java is designed to be easy to learn. If you
understand the basic concept of OOP Java, it would
be easy to master.
With Java's secure feature it enables to develop
virus-free, tamper-free systems. Authentication
techniques are based on public-key encryption.

5. 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.

6. 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.

7. Java makes an effort to eliminate error
prone codes by emphasizing mainly on
compile time error checking and
runtime checking. But the main areas
which Java improved were Memory
Management and mishandled
Exceptions by introducing automatic
Garbage Collector and Exception
Handling.
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 is also a distributed language.
Programs can be designed to run on
computer networks. Java has a special
class library for communicating using
TCP/IP protocols. Creating network
connections is very much easy in Java
as compared to C/C++.

8. 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.
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.
