Can vscode run kotlin

Running Kotlin in VS Code requires the following environment configuration: Java Development Kit (JDK) and Kotlin compiler Kotlin-related plug-ins (such as Kotlin Language and Kotlin Extension for VS Code) create Kotlin files and run code for testing to ensure successful environment configuration

VS Code Run Kotlin: A powerful tool and potential pitfalls for efficient development

Prepare your development environment first. VS Code itself is just an editor. To run Kotlin, you need to install the Java Development Kit (JDK) and Kotlin compiler first. The JDK provides the Kotlin runtime environment, and the Kotlin compiler converts your Kotlin code into Java bytecode, which is ultimately executed by the Java virtual machine (JVM). You can download JDK from the Oracle official website, and the Kotlin compiler can be downloaded through SDKMAN! or directly from the Kotlin official website. After the installation is complete, remember to configure the environment variables so that the system can find the JDK and Kotlin compilers.

After completing the above steps, enter the VS Code plug-in market to install Kotlin-related plug-ins. I personally recommend the two plugins, Kotlin Language and Kotlin Extension for VS Code. The former provides basic functions such as syntax highlighting, code completion, and reconstruction, while the latter adds advanced functions such as debugging, running and testing. After installing the plug-in, VS Code will automatically recognize the Kotlin file and provide corresponding code prompts and intelligent perception.

What you need to note here is the version compatibility of the plug-in. Sometimes new versions of plugins may be incompatible with older versions of JDK or Kotlin compilers, causing some unexpected problems. If you encounter problems, try updating or falling back on the plugin version, or checking if the versions of the JDK and Kotlin compilers match. I once spent half a day troubleshooting a simple running error because of the plug-in version problem.

At this stage, you need to create a simple Kotlin file to test your environment. For example, create a file named HelloWorld.kt and write the following code:

 <code class="kotlin">fun main() { println("Hello, World!") }</code>

After completion, check whether the code can be run successfully. You can directly compile the code using the kotlinc HelloWorld.kt -include-runtime -d HelloWorld.jar command in the VS Code terminal, and then run the generated JAR file with the java -jar HelloWorld.jar command. Of course, the Kotlin plug-in for VS Code also provides a more convenient way to run, usually running the current file with just a click of a button.

VS Code combined with Kotlin plug-in can indeed greatly improve Kotlin development efficiency. Code completion and smart prompt functions save a lot of time, and the debugging function is also very powerful, which can quickly locate and solve code problems. Especially for large projects, VS Code's code navigation and reconstruction functions are indispensable.

However, VS Code is not perfect either. Sometimes, some bugs may occur in the plug-in, causing the code prompts to be inaccurate or the debugger cannot work properly. Additionally, for very complex projects, VS Code's performance may be affected, especially when dealing with large files. At this time, it might be better to consider using a professional IDE like IntelliJ IDEA. But for most Kotlin projects, VS Code is competent enough, and its lightweight and cross-platform features make it a very good development tool. Which tool to choose ultimately depends on your project size, personal preferences, and team habits.
