What is ‘Java’, which we have seen on many devices from computers to mobile phones, and what does it do?

Java, which we encounter on many digital devices whether connected to the Internet or not, is both a programming language, a computing platform and an application running software. Let’s examine in all details what is Java, which is thought to shape the world of the future as well as today’s world.

Even if you are not a programmer or application developer, you must have heard of Java. Because in almost all digital devices we use, we encounter applications prepared with Java, whether they are connected to the internet or not. If you are a software developer or application developer You already need to be proficient in Java because for a long time, the way to develop applications passes through Java.

The answer to the question of what is Java is a bit complicated because Java is both a programming language, a computing platform, and software that the end user can use to run applications. In other words, if we look at it from this perspective, Java is shaping our digital world today as it has in the past, and it seems to shape it in the future as well. Bride What is Java and what does it do Let’s examine the answers to frequently asked questions such as:

What is Java?

Developed by Sun Microsystems, Java was first released in 1995. Java; widely used, class-based, object-oriented is a programming language. Java is also a computing platform for application development and execution. Java is also an application run software that the end user can download free of charge.

Since Java is a programming language that has been used for many years, it has received many different updates over the years and Different versions have been published. Finally, Java SE 15 version was released in September 2020. The software that users will download to run applications is the Java 8 version.

Java software that users will use to run applications While the Java Runtime Environment is called JRE for short, Java Virtual Machine, the computing platform used by application developers, is called JRM for short. There is also a Java Development Kit (JDK) tool that application developers can use. You can access all these services by entering the Java official website on the link here.

What does Java do?


You can develop an application with Java, test this application and present the infrastructure that the user can use this application. What good is Java at this point? What to do with Java It would be much more reasonable to ask. Here are some of the things you can do with Java:

  • You can develop applications for devices with Android operating system.
  • You can create enterprise software in Java language.
  • You can develop mobile Java applications.
  • You can develop a calculation application.
  • You can do big data analysis.
  • You can program the device compatibility of the hardware via Java.
  • You can use it in technologies such as Apache, JBoss, GlassFish.
  • You can use the Java application launcher with the JDK.
  • With the JDK compiler you convert code to bytecode.
  • You do class loading with the JDK Java application launcher.
  • With the JRE you run all Java applications.
  • With the JRE you use all the libraries and package classes.

Highlights of Java:


  • It is one of the easiest programming languages ​​to learn.
  • Written in Java code, the base works on almost all computing platforms.
  • Since codebases written in Java are platform independent, an application written on one machine will run on different machines.
  • Ideal for object-oriented application development.
  • It easily handles multiple operations as it has automatic memory management.
  • Ideal for the internet environment.
  • Network-centric distributed computing facilitates processing.

Here are some of the prominent advantages of using the Java programming language and other Java services. certainly according to the user and the platform on which the application will be developed Different advantages can be added to this list or features that are seen as advantages may turn into disadvantages. However, it is still possible to say that the advantages always prevail.

Java platform types and features:

  • Java Standard Edition
  • Java Enterprise Edition
  • Java Micro Edition
  • JavaFX


Java Standard Edition:

Java Standard Edition, briefly Java SE, which offers the basic functions of the Java programming language; all types and objects definitions for top-level classes. You can use it when networking, for security purposes, for database access, creating GUI for GUI, and parsing XML.

Java Enterprise Edition:

Java Enterprise Edition, which provides a higher level of service, in short Java EE; highly scalable, It is used to develop larger scale, multi-layered and secure network applications. Applications developed with Java EE are more reliable and offer a wider runtime environment.

Java Micro Edition:

Java Micro Edition, abbreviated as Java ME on small devices such as smartphones and tablets Runs applications developed with the Java programming language. Java Micro Edition offers its users a virtual machine that takes up much less space.


Java FX offers its users a much simpler interface. rich internet based applications It is a platform for development. Unlike standard Java, it uses graphics and media engines that help you take advantage of APIs that connect to higher-performance clients and networked data sources.

Signing that it will shape the world of the future by shaping today’s internet and digital world, What is Java and what does it do We answered the curious topics such as and talked about the details you need to know about the Java system.
