title: Using Java libraries in Scala
body: <p>I am new to Scala. I am only able to write basic code thus far, but I want to start using it more concretely, rather than just learning theory.</p>
  <p>Let's say I have the following Java code in <em>HelloWorld.java</em>:</p>
  <pre><code>public class HelloWorld {
  
      public static void main(String[] args) {
          System.out.println(&quot;Hello, World&quot;);
      }
  
  }
  </code></pre>
  <p>What would the code be to invoke it from Scala?</p>
