Java Programming Languages & Features of Java

Last Updated on: August 11, 2020 By Softwaretestingo Editorial Board

What We Are Learn On This Post

  • Java Programming Languages Features

Java Programming language: Java is such a type of programming language which is class-based, object-oriented, and concurrent. One of the main features of the Java Programming language is “write once, run anywhere (WORA).” The meaning of WORA writes the java program for a single time and compile the java code. After that, you can run the compile java code in any platform like windows, mac, Linux without doing recompilation.

We are posting a series of tutorials on Core Java and Selenium. So that every tester and Java learner also get benefitted. Follow those links to get the full idea on those topics.

Java Programming Languages Features

Let’s discuss some of the Java Programming features :

  • Simpler: Java programming language is easy to learn because it does not include concepts like pointers and operator overloading, which is available in C++.
  • Object-Oriented: It is one of the main features of Java by which it is one of the most popular languages. Because of this feature, you can model the program into an object which can have data and behavior. Java has four object-oriented concepts like Abstraction, Encapsulation, Polymorphism, and inheritance.
  • Robust Language: Java language developed in such a way that it can do early checking for possible errors. Where we can say that when the compiler compiles the java code that time java compiler can detect the java errors, but when you compare this feature with another programming language, maybe you may not find such rich features. There are other few features are there which make java is robust like garbage collection, Exception Handling, and memory allocation.
  • Secure: In Java You May not find concepts like a pointer, and you can not access the out of boundary arrays element in java, which makes Java more secure.
  • Architecture Neutral: Java is Architecture neutral because java does not have such types of features which are dependent on the architecture of the environment. For example, the size of the primitive data type in java has fixed, which is 4 bytes. In contrast, the c programming languages int data type takes 2 bytes memory for 32-bit architecture and 4 bytes for the 64-bit architecture.
  • Multithreading: Because of Multithreading feature of java, you can able to run parallelly execution of two or more parts of the program by which you can able to do maximum utilization of CPU.
  • Platform Independent: As we already shared that after compile you get the bytecode, which is platform independent so you can execute the same code in a different system and different environment by this feature Java is platform-independent or portable.

Along with all the above Java Programming feature, java programmers also get benefits from the Good Java community members and other benefits like:

  • Oracle powers java: As you know that Java acquired by one of the best leaders of Industry Oracle. So you get more support from big companies like IBM, Google, Redhat.
  • You will get lots of open source libraries that help to build your application or help you with your project.
  • There are lots of tools and IDE are available to write, compile, and run your project. With those tools, you can be more productive.
  • Many frameworks help you build highly reliable applications quickly.
  • The community around Java technology is massive and mature so that you can get support quickly.

Because of such rich java features, Java is ranking in #1 as the programming language in the world by popularity. So we are happy to congratulate you on choosing Java as a programming language for developing or testing your application.  If you want to learn all the features of Java, then follow our complete core java tutorial series of posts. And let me know if we missed something in the comment section.

    What are the Java features?
    java programming language have somany features out of which some of the important features of java are Java is Simple, Familiar, Object-Oriented programming language, Robust, Secure, High Performance, Multithreaded, Platform Independence

    Which feature makes Java so useful for Internet programming?
    Java is distributed because it facilitates users to create distributed applications in Java. RMI and EJB 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.

    What is the most important feature of Java?
    Important features of Java: Java is object-oriented programming language, so it allows to create modular programs and reusable codes. simple, object-oriented, distributed, secure, architecture, robust, multi threaded and dynamic language.

    What is the main use of Java?
    Java is a widely used programming language expressly designed for use in the distributed environment of the internet.

    Why Java is most popular programming language?
    The main reason for this is because it is safe, portable, maintainable and comes with better high-level concurrency tools than C++ or any other language.

    Why Java is robust programming language?
    Java is Robust because it is highly supported language. It is portable across many Operating systems. Java also has feature of Automatic memory management and garbage collection. Strong type checking mechanism of Java also helps in making Java Robust

    How does Java enable high performance?
    Java enabled High performance by introducing JIT- Just In Time compiler , JIT helps the compiler to compile the code On demand basis i.e which ever method is called only that method block will get compiled making compilation fast and time-efficient. This makes the java delivering high performance.
