How do you use jpackage with a simple code example?

jpackage is a tool provided by the Java Development Kit (JDK) that allows developers to create native installers for Java applications. It packages your Java application along with a Java Runtime Environment (JRE) so that users can easily install and run your application without needing to install Java separately.

Simple Example of jpackage

Below is a simple example of how to use jpackage to create a native installer for a Java application.

Step 1: Create a Simple Java Application

Create a Java file named HelloWorld.java with the following code:

public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } }

Step 2: Compile the Java Application

javac HelloWorld.java

Step 3: Create the Native Installer using jpackage

Run the following command to create a native installer:

jpackage --input . --name HelloWorldApp --main-class HelloWorld --type exe

jpackage Java application native installer JRE Java Development Kit
