The short answer: I recommend that you go with at least JDK version 17 by Adoptium Eclipse Temurin. Which version of the JDK should I install? For example, if you want to use the newer functional programming features found in Java 8, then you need to install at least the Java 8 JDK. Since the JDK supplies the compiler for your Java programs, the JDK you install determines what Java version you are able to code in. You should see something like this if you have a JDK installed: You can check if you have a JDK is installed by running the command java -version on the command-line. A JDK is the development environment used for compiling and executing Java applications. To use Java within Visual Studio Code, you need to install a Java Development Kit (JDK) on your computer. Step 1 - Install a Java Development Kit (JDK) However, I will go through how to setup things up from zero, with some beginner-friendly explanation.Īlso, I will see how VS Code fares with Spring Boot applications, and see if you can benefit from using some extensions for this. The VS Code docs has a Java guide that covers things quite well. It should be quick and easy to get up and running, but is it? If you do not know what a JDK is, don’t worry we will get to it! Also you need a Java Development Kit (JDK) installed. = "/mambo.To setup VS Code for Java development, you need to install some extensions to provide core language features such as compilation and execution of Java programs, debugging, syntax highlighting, formatting, and code completion. Then we will create a new simple java class called HelloServlet.java inside directory src\main\java\com\myservlet\HelloServlet.java. Now we are ready to start creating our servlet, We will start by deleting the default App.java file generated by the IDE inside directory src\main\java\com\myservlet\App.java. 1 provided rvlet jstl 1.2 javax javaee -web -api 8.0 provided Without this dependencies we wont be able to build our servlet. Add Dependenciesīefore we start code our servlet we need to add the important dependencies for project in pom.xml file. The project will be complied with maven. Ĭlick on Terminal on top bar then click Run Build Task and then compile Now It's time to compile our project with maven to make sure everything is okay. Select maven: executes common maven command.Īfter the above tasks.json file will be generated. Open the Command Palette (CTRL + SHIFT + P) and type and Configure tasks fileĪfter you successfully generate the project It is time to configure tasks file so as it can used to compile the project with maven. Locate your destination folder which you created before, then generate the project there. Let's Install the Visual Studio extension pack for java in the VSC by hold (CTRL + SHIFT + X) inside VSC and type vscode:extension/vscjava.vscode-java-pack.Ĭreate a folder to your desired location which will be used for your project.įrom the Command Palette (Crtl+Shift+P) in Visual Studio Code, then Make sure to follow the proper procedural on installing all the mentioned technologies.Īfter the Installation of the above we need to set working platform by adding some extensions to VSC that will assist us in creating out project. I will be using window 10 for this tutorial but I believe most of the important steps will be the same in other OS like ubuntu, Mac etc.įirst we need to Download and install Java 8, Apache Maven, Tomcat 8 Server and Visual Studio Code(VSC) IDE into your system. Before we begin, It is good to note that this article is intended not to use some of the supportive frameworks, which most of them will perform most of the work without developer much efforts, so it is good to say it is intended to focus on the core technologies just for the purpose of learning.
