![]() The text " Write." requests to create a Java program that uses OpenCV.The init ImageProcessor.java argument will create a new ImageProcessor.java file in the directory where the command executes.The -preview argument for using preview features, e.g., ChatGPT.$ jbang -preview -verbose init ImageProcessor.java "Write a Java program that processes an input image and add text Hello world on it using OpenCV to produce an output image called output.png" Usually, anyone learning OpenCV in Java would need to know the intrinsic details of image processing and its components and concepts to understand dependencies before even beginning to write any code. In the following example, the command creates Java code that takes an image, adds text, and then writes it to the filesystem. The enhancements introduced also bring some exciting ergonomics, e.g., a developer doesn't necessarily need to figure out all the intrinsic details of an API. Furthermore, it will allow Java developers to use the preview features like String templates. The command will download the early-access release of OpenJDK 21 in case there isn't one on the system. $ jbang -java 21 -enable-preview -c 'print(STR."First arg is \!")' JBang To use JBang with Java 21 preview features, simply run the following command: Furthermore, developers can also request via CLI to generate code with OpenAI’s ChatGPT or even create plugins in Java for ChatGPT. Java developers can now execute Java code with JBang using the upcoming release of Java 21, scheduled for September 19, 2023. It was developed to simplify the execution of Java code more interactively and conveniently, similar to languages like Python. JBang is a lightweight Java-based scripting tool that allows developers to write and run Java code directly from the command line without requiring an entire Java project or compilation steps. JBang has also recently introduced the integration of ChatGPT via the CLI, allowing developers to create JBang scripts using ChatGPT. The latest JBang release provides a preview of Java 21 and more integration with the OpenAI plugin via the quickstart port to Java. ![]()
