Featurers of Java Programming Language

The primary objective of Java programing language creation was to form it portable, simple and secure programing language .

The features of Java also are referred to as java buzzwords.

Most Important features of java programming languages are given below:

  • Simple
  • Object-Oriented
  • Portable
  • Platform independent
  • Secured
  • Robust
  • Architecture neutral
  • Interpreted
  • High Performance
  • Multithreaded
  • Distributed
  • Dynamic

Brief Explanation of features of Java


Java is extremely easy to learn , and its syntax is straightforward , clean and straightforward to know . Java language may be a simple programing language because:
  • - Java syntax is predicated on C++. so, it's easy to find out it after C++.
  • - Java has removed many complicated and rarely-used features, for instance , explicit pointers, operator overloading, etc.
  • - there's no got to remove unreferenced objects because there's an Automatic garbage pickup in Java.


Java is an object-oriented programing language . Everything in Java is an object.

Object-oriented programming (OOPs) may be a methodology that simplifies software development and maintenance by providing some rules.

Basic concepts of OOPs are:
  • Object
  • Class
  • Inheritance
  • Polymorphism
  • Abstraction
  • Encapsulation


Java is portable because it facilitates you to hold the Java bytecode to any platform. It doesn't require any implementation.

Platform Independent

Java is platform independent because it's different from other languages like C, C++, etc. which are compiled into platform specific machines while Java may be a write once, run anywhere language.

There are two sorts of platforms software-based and hardware-based. Java provides a software-based platform.

The Java platform differs from most other platforms within the sense that it's a software-based platform that runs on the highest of other hardware-based platforms.

It has two components:
  • Runtime Environment
  • API(Application Programming Interface)
Java code are often run on multiple platforms, for instance , Windows, Linux, Sun Solaris, Mac/OS, etc.

Java code is compiled by the compiler and converted into bytecode.

This bytecode may be a platform-independent code because it are often run on multiple platforms.


Java is best known for its security.

Using Java, we will develop virus-free systems.

Java is secured because:
  • No explicit pointer
  • Java Programs run inside a virtual machine sandbox
  • ClassLoader in Java
  • Bytecode Verfier
  • Security Manager


Robust simply means strong.

Java is strong(robust) because:
  • It uses strong memory management.
  • pointers aren't available in java that avoids security problems.
  • Java uses automatic garbage pickup which runs on the Java Virtual Machine to urge obviate objects which aren't getting used by a Java application.
  • There are exception handling and therefore the type checking mechanism in Java.

All these points make Java robust.

Architecture neutral

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 byte code is translated on the fly to native machine instructions and isn't stored anywhere.

The development process is more rapid and analytical since the linking is an incremental and lightweight process.

High Performance

Java is quicker than other traditional interpreted programming languages because Java bytecode is "close" to native code.

It is still a touch bit slower than a compiled language like C++.

Java is an interpreted language that's why it's slower than compiled languages like C, C++, etc.


A thread is sort of a separate program, executing concurrently. we will write Java programs that affect many tasks directly by defining multiple threads.

The main advantage of multi-threading is that it doesn't occupy memory for every thread. It shares a standard memory area.


Java is meant for the distributed environment of the web .

Java is distributed because it facilitates users to make distributed applications in Java.

This feature of Java makes us ready to access files by calling the methods from any machine on the web .


Java may be a dynamic language. It supports dynamic loading of classes. It means classes are loaded on demand. It also supports functions from its native languages, like C and C++.
