You can do this in Java 21, create this small Java file and run it immediately:

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

Include the .java extension, you're running the file directly.

time java HelloWorld.java

    Hello, World!
