Java is a platform-independent language. For example, when you try to run a java program, the output is called a bytecode. See platform and environment. It may contain words, phrases, etc which the machine does not understand. Java being the platform independent language allows its end users to access its source code on any other language automatically. In contrast, "platform independent" means that the application can run in different operating environments. Writing code in comment? That is on a specific operating system. Get hold of all the important Java and Collections concepts with the Fundamentals of Java and Java Collections Course at a student-friendly price and become industry ready. Platform Dependent means the program / software that we have developed can run /execute (show results) on a specific platform. Platform means hardware + operating system. For example, the Java programming language was designed to run on multiple types of hardware and multiple operating systems. In the case of java, after compiling the java program, we will get byte code as an output. This class file can run using JRE. Behavior will be same (on MAC, LINUX, and WINDOWS)). So, here comes the role of a compiler. For every operating system separate JVM is available which is capable to read the.class file or byte code. What does java platform independent means? are available and work in the same way on all platforms. The compiler converts the high-level language (human language) into a format understood by the machines. Its source code can be used to work on a different platform which makes it an independent platform to work on. java is platform independent Posted by vengatesh krishnan March 15, 2020 March 16, 2020 Posted in Uncategorized Platform is … One of the major features of java includes that why java is called platform independent language. When we try to run this .exe file on another OS it does not run, since it is OS dependent and hence is not compatible with the other OS. Java is platform independent language (In simple terms we can run (.class file) on any platform. Those are very simple to use. This executable code may be a sequence of machine instructions that can be executed by the CPU directly, or it may be an intermediate representation that is interpreted by a virtual machine. Why Java is Platform Independent Language? Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform-independent byte code. Java is a platform independent programming language, Because when you install jdk software on your system then automatically JVM are installed on your system. Generally, they can be used interchangeably. A simpler cost effective solution is to use portable, platform independent code that runs on variety of CPU's under different environments. Platform independent means that the code remains the same irrespective of the platform involved. Platform independent means the program that we have developed can run on any platform. Also, the criteria for deciding on platform independence might vary from person to person. Java is a platform independent language, which means the java program can be executed on any platform in the world, whether it is a different architecture hardware / processor or different operating system like Linux / … Before getting into details of this first we should know what platform independence is. This interpreter is the JVM and thus the Bytecode is executed by the JVM. Comment document.getElementById("comment").setAttribute( "id", "a9c9b53a3c633b6b65b0e2fe43bcc429" );document.getElementById("ia9f9db009").setAttribute( "id", "comment" ); Save my name, email, and website in this browser for the next time I comment. For the source code to be known by the machine, … Cross-platform means that the application runs on many platforms. We use cookies to ensure you have the best browsing experience on our website. It may contain words, phrases, etc which the machine does not understand. If we take an example of platform dependent language then we can be clearer about how JVM is giving platform independence to java. And finally program runs to give the desired output. It implies that it doesn't matter on what operating system(lets say,Windows OS) the code was written, it could be run on the other operating system(lets say Linux) conveniently and without any issue. JVM- interpreter that converts byte code to … A program is written in a language which is a comprehensible language. Lets try to visualize this scenario using pictures. That’s why javas Moto is WORA (write once run anywhere) Hence we can write java code on windows operating system, compiled it on iOS and run it on UNIX operating system. The programming language like C and C++ do not generate any intermediate code like bytecode in java. Platform-independent software can be used in many different environments, requiring less planning and translation across an enterprise. So java developers aimed at one programming language which can be used irrespective of the platform. In other words, you can write your code once and then run it anywhere, on any platform that provides the environment to run it. Java package is coming with JDK (Java Runtime Environment) and JRE (Java Runtime Environment). This java virtual machine is very standard one. Java Platform Independent Language For more courses : http://www.wingslive.com/Ws_wl_Web_free_Courses.aspx Platform-independent means that code executes without a specific platform. Attention reader! It might contain words, phrases and so forth which the machine does not understand it. Let us take our familiar language ‘C’ which is platform dependent. Java package is coming with JDK (Java Runtime Environment) and JRE (Java Runtime Environment). This environment is the Java Virtual Machine (JVM). The meaning of platform independent is that, the java source code can run on all operating systems. JVM reads bytecode and translate bytecode to … If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. For the source code to be understood by the machine, it needs to be in a language understood by machines, typically a machine-level language. Java has something called a virtual machine called JVM or Java Virtual Machine. Solve Missing Return Statement Error in Java, Difference between Hashtable and HashMap in Java. Experience. Platform Independence: It means if we have written a program it should run on any platform without any modifications. JVM give platform independence to java. Platform independent practically means “write once run anywhere”. The meaning of platform independent is that, the java source code can keep running on every operating system. This fact can be verified by trying to download the JVM for your particular machine – when trying to download it, you will be given a list of JVMs corresponding to different operating systems, and you will obviously pick whichever JVM is targeted for the operating system that you are running. A program is written in a language which is a human readable language. See your article appearing on the GeeksforGeeks main page and help other Geeks. Important Points: This article is contributed by Sania Parween. Here we can write java program and compile that code in our system itself. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. languages are Ruby, Lisp, Scheme, Scala, Clojure, Python, Perl, PHP, C# and the list goes on. For every operating system separate JVM is available which is capable to read the .class file or byte code. But it is not in the case of java. A program is written in a language that is a human-readable language. Required fields are marked *. This byte code can run on a virtual machine that is java virtual machine. Different JVMs are available for each type of platform. This is the great benefit for some one coming from platform dependent programming language like C or C++ whose code needs to be ported for every single platform … Therefore, a compiler is a program that translates the source code for another program from a programming language into executable code. After writing C program we will compile the code it will provide .out file. Java Virtual Machine (JVM) is a specification that provides runtime environment in which java bytecode(.class files) can be executed. Java is developed for emerging need of a programming language for embedded devices. But only one thing is JVM should be installed on that system on which we want to execute our byte code. If we are developing an application we can deploy it on any platform. What happens in case of Java is that the JVM once installed on any platform like windows or OS X can run the java code without any alteration. The main difference between AWT and Swing in Java is that the AWT is Java’s original platform-dependent windowing, graphics, and user interface widget toolkit while the Swing is a GUI widget toolkit for Java that is an extension of AWT.. Java is a high-level, general-purpose programming language that supports object-oriented programming, multithreading, platform … Thus, it exhibits the ability to be platform independent, meaning it can execute a code regardless of the operating system on which it is being executed.
