Features of Java

In this tutorial you will learn about the features of java. Here we provide a list of most important feature of Java that are help to increase your marks in exams.

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 plays an important role in the popularity of this language.

List of most important features of java is given below.

  1. Simple
  2. Object-Oriented
  3. Portable
  4. Platform independent
  5. Secure
  6. Interpreted
  7. Robust
  8. Architecture neutral
  9. High Performance
  10. Dynamic
  11. Distributed
  12. Multithreaded

we define below, all the features of Java programming languages, so start the learning.


Simple means, Java is very easy to learn, and its syntax is very simple, clean and easy to understand. According to Sun Microsystem, Java language is a simple programming language.

Some points are given below that says Java is a Simple language; –

  • Java syntax is based on C++ (so easier for programmers to learn it after C++).
  • Java has removed many complicated and rarely-used features, for example, explicit pointers, operator overloading, etc.
  • There is no need to remove unreferenced objects because there is an Automatic Garbage Collection in Java.


Java is an object-oriented programming language. Everything in Java is an object. Object-oriented means we organize our software as a combination of different types of objects that incorporates both data and behavior.

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


Java is portable programming language because it facilitates you to carry the java bytecode to any platform. It doesn’t require any implementation, so java is called portable language.

Platform independent

Java is platform independent because it is different from other languages like C, C++, etc. which are compiled into platform specific machines while Java is a write once, run anywhere language. A platform is the hardware or software environment in which a program runs.

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

The Java platform differs from most other platforms in the sense that it is a software-based platform that runs on the top of other hardware-based platforms. It has two components.

  1. Runtime Environment
  2. API (Application Programming Interface)

Java code can be run on multiple platforms, for example, Windows, Linux, Sun Solaris, Mac/OS, etc. Java code is compiled by the compiler and converted into bytecode. This bytecode is a platform-independent code because it can be run on multiple platforms, i.e., Write Once and Run Anywhere.

Java is best language known for its security level. With Java, we can develop virus-free systems.

Java is very secured because; –

  • No explicit pointer
  • Java programs run inside a virtual machine sandbox.
  • Class loader
  • Bytecode Verifier
  • Security Manager etc.

Java language provides these securities by default, some security can also be provided by an application developer explicitly through SSL (Secure Sockets Layer), JAAS (Java Authentication and Authorization Service), Cryptography, etc.


It converts the high-level program into assembly language (machine language).
Java interpreter is a computer program (
system software) that implements the JVM. It is responsible for reading and executing the program. It is designed in such a way that it can read the source program and translate the source code instruction by instruction.


Robust simply means strong, it utilizes strong memory management. That can handle run-time errors as it checks the code during the compiler and runtime. If any runtime error is identified by the JVM. If will not be passed directly to the underlying system.

Architecture neutral

Java is architecture neutral because there are no implementation dependent features, for example, the size of primitive types is fixed.

In C programming, int data type occupies 2 bytes of memory for 32-bit architecture and 4 bytes of memory for 64-bit architecture. However, it occupies 4 bytes of memory for both 32 and 64-bit architectures in Java.

High Performance

Java is high performance because it is faster than other traditional interpreted programming languages because Java bytecode is “close” to native code. It is still a little bit slower than a compiled language (e.g., C++).


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

Java supports dynamic compilation and automatic memory management (garbage collection).


Java is distributed because it facilitates users to create distributed applications in Java. RMI (Remove Method Invocation) and EJB (Enterprise Java Bean) are used for creating distributed applications. This feature of Java makes us able to access files by calling the methods from any machine on the internet.


A thread is like a separate program, executing concurrently. We can write Java programs that deal with many tasks at once by defining multiple threads. The main advantage of multi-threading is that it doesn’t occupy memory for each thread. It shares a common memory area. Threads are important for multi-media, Web applications, etc.

So, in this tutorial you learned all about the Features of Java, I hope you read this tutorial well and learn something about the Java’s Feature. If you have any doubt about this tutorial, you can ask in the comment section.
