These two steps: compilation and execution require two specific pieces of software that are part of the Java Development Kit, also known as the JDK. Once the compiler produced the binary file that you need, you can execute this binary file, that will your program. All you need to do is copy it and paste it in your text editor. Do not worry, this page gives you the code you are going to compile. The precise description of what is this byte code is beyond the scope of this tutorial.Ĭompiling some code may fail your code has to be correct for the compiler to produce an executable version of it. This is a technical term that you may come across. ![]() This code contains special binary codes called byte code. Whereas you can read a source code and understand it, binary or executable files are not meant to be read by a human person. The file produced by a compiler is often called a binary file or an executable file. Every compiler is specific to a language. ![]() Some languages do not have a compiler Java does. This transformation is conducted by a special piece of software called a compiler. Then this code has to be transformed to another format, which can be executed by your computer. ![]() The first of these steps is to write some Java code in a text editor. If you need to create an enterprise application, the creation process is more complex but at its core you will find these simple steps. This tutorial shows you how to create a very simple Java application. There are several steps that you need to follow to create a Java application. But before we move on, I would like to do through several elements that you need to know to fully understand what you are doing.Įven if you are familiar with some other programming language, know about compilation, know what an executable file is you may be interested in the following because Java works in a way that differs from C or C++. I understand that you are eager to type some code in your editor and run it to see your first Java application in action! Do not worry, your expectation will be fulfilled by the end of this tutorial.
