Features of Java

Being a mobile, simple and secure programming language was the main objective behind the creation of the Java programming language. These are just the initial level of advantages of Java that were present in the language. There are numerous of astonishing features that play a terrific role in the massive popularity of this unique language. Java buzzwords is the name that has been assigned for the advantages of Java.

Here is a list of the most prominent advantages of the Java language that is depicted below.

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

1. Simple

It is one of the simplest language that you will ever come across in your life. It is extremely easy to learn the Java language because of the fact that its syntax is simple, not messy and can be easily understood. Here are some of the facts that are provided by the Sun that is the developing company of Java in the favor that Java language is a simple programming language:

  • The syntax of Java is basically based on the C++ and hence, programmers can easily learn it after C++).
  • There were many complicated and rarely-used features that has been removed from the Java, for instance, explicit pointers, operator overloading, etc.
  • Unreferenced objects don’t have a need to be removed from the Java as Java has an Automatic Garbage Collection.

2. Object-oriented

As a matter of fact, we all are aware that Java is an object-oriented programming language and everything that is present in Java is basically an object. Object-oriented generally elaborates to the feasibility to organize the software as a combination of different types of objects that mutually incorporates both the data and behavior. A methodology that generally simplifies the software development and maintenance just by providing some rules is known as the Object-oriented programming (OOPs). Here are some of the basic concept of the OOPs:

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

3. Platform Independent

Java is generally known as a platform independent language that simply means that it can be run on various platforms. And the reason behind being independent is that it differs from other programming languages like C, C++, etc. that are compiled in to a platform specific machines. But Java follows a procedure of write once, run anywhere. To simply the understanding process please note that the platform is basically the hardware or software environment in which a program runs. The Java platform differs from most of the other platforms in the sense that it is a software-based platform that basically runs on the top of the other hardware-based platforms. This platform generally have two components that are depicted below:

  • Runtime Environment
  • API(Application Programming Interface)

The Java code is very adaptable and can be executed on various platforms like, Windows, Sun Solaris, Linux, Mac/OS, etc. Java code is converted into bytecode after being compiled by the compiler. The bytecode can be executable on multiple platforms and hence, it is called as the platform-independent code.

4. Secured

If you want to secure your code the Java is the language for you. Virus-free systems can be developed by the help of Java. Java is secured because:

  • There is no explicit pointer.
  • Java Programs can also run inside a virtual machine sandbox.
  • Classloader: A part of the Java Runtime Environment (JRE) that is generally used to load Java classes into the Java Virtual Machine dynamically is known as Classloader in Java. This one adds the security just by separating the package for the classes of the local file system from the classes that have been imported from the network sources.
  • Bytecode Verifier: This checks the code fragments for any of the illegal code that may violate the access right to the objects.
  • Security Manager: This manager generally determines what resources a class may access.

5. Robust

Robust is a word that points towards being strong. And the Java is known to be robust because of the facts that are depicted below:

  • Java language generally uses the strong memory management.
  • There is a lack of pointers in the Java language that are used to avoid the problems regarding security.
  • Java language has an automatic garbage collection that runs on the Java Virtual Machine in order to get rid of the objects that are no longer in use by a Java application anymore.
  • Exception handling and the type checking mechanism are present in the Java language.

6. Architecture-neutral

Java is an architecture neutral language because of the fact that there are no implementation dependent features in it.

7. Portable

Java language is portable as we have discussed above it facilitates the programmer the feature of carrying the Java bytecode to any platform without any implementation.

8. High-performance

Java language is known to faster than other traditional interpreted programming languages as Java bytecode is generally "close" to the native code. However, this language is a little bit slower than a compiled language and the reason is that Java is an interpreted language.

9. Distributed

Java language is basically distributed as it facilitates the programmer to create distributed applications in it. RMI and EJB are the two components that are used for creating distributed applications.

10. Multi-threaded

A thread is basically just like a separate program that is executes concurrently. Programmers can write Java programs that deal with multiple tasks at one time just by defining the multiple threads. It doesn't occupy memory for each thread and this is the main advantage of the multi-threading and this is known to share a common memory area.

11. Dynamic

As a matter of fact we known that Java is a dynamic language and is famous for supporting dynamic loading of the classes. In simple words, classes can be loaded on demand and that supports the functions that are from its native languages that are C and C++. Dynamic compilation and automatic memory management that is also known as the garbage collection are generally supported by the Java language.
