A list of the most important features of Java language is given below.

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


In Java, everything is an object. Java can be easily extended as it is based on the Object model.

Basic concepts of OOPs are:

  • Object
  • Class
  • Inheritance
  • Polymorphism
  • Abstraction
  • Encapsulation

Platform Independent

Unlike many other programming languages, including C and C ++, when Java is compiled, it is not compiled on a platform-specific machine, but platform-independent bytecode. This bytecode is distributed over the web and is interpreted by the virtual machine (JVM) on whatever platform it is running on.


Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it will be easy to master.


With the secure function of Java, it allows developing systems free of viruses and without alterations. Authentication techniques are based on public-key encryption.


The Java compiler generates an architecture-neutral object file format, which makes compiled code executable on many processors, with the presence of the Java runtime.


Being architecture-neutral and having no implementation-dependent aspects of the specification, Java is portable. The compiler in Java is written in ANSI C with a clean portability limit, which is a POSIX subset.


Java makes an effort to eliminate error-prone situations by primarily emphasizing compile-time error checking and runtime checking.


With Java's multithreaded feature, it is possible to write programs that can perform many tasks simultaneously. This design feature allows developers to build interactive applications that can run smoothly.


Java bytecode is translated on the fly to native machine instructions and is not stored anywhere. The development process is faster and more analytical as linking is an incremental and lightweight process.

High performance

With the use of Just-In-Time compilers, Java enables high performance.


Java is designed for the distributed environment of the Internet.


Java is considered to be more dynamic than C or C ++ as it is designed to adapt to an evolving environment. Java programs can contain a large amount of information at run time that can be used to verify and resolve accesses to objects at run time.
