Is there way to configure Java 19 (or upper) in VS Code?

Prerequirements: installed Java 19 on your computer (read this article).

Under Windows:

1. press Ctrl+Shift+P keys,
    
2. find and select Preferences: Open User Settings (JSON) option,
    
3. add "java.configuration.runtimes" configuration,
   e.g.:

   {
       // ...
       "java.configuration.runtimes": [
         {
           "name": "JavaSE-11",
           "path": "C:\\Program Files\\Eclipse Adoptium\\jdk-11.0.19.7-hotspot",
         },
         {
           "name": "JavaSE-17",
           "path": "C:\\Program Files\\Eclipse Adoptium\\jdk-17.0.8.101-hotspot",
         },
         {
           "name": "JavaSE-19",
           "path": "C:\\Program Files\\Eclipse Adoptium\\jdk-19.0.2.7-hotspot",
           "default": true
         }
       ],
       // ...
   }

   Note: you can use other JDK than Eclipse Adoptium.

Sometimes it may be needed to change Java version to 19 in pom.xml file when you use Maven project.
e.g.:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>my-project</artifactId>

    <properties>

        <maven.compiler.source>${java.version}</maven.compiler.source>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    </properties>

    <dependencies>

        <!-- ... -->

    </dependencies>

    <build>
        <finalName>${project.artifactId}</finalName>
        <sourceDirectory>src</sourceDirectory>
        <testSourceDirectory>test</testSourceDirectory>
        <plugins>
            <plugin>

                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <source>${maven.compiler.source}</source>
                    <target>${maven.compiler.target}</target>
                    <verbose>true</verbose>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>
