title: How to use line break argument
body: <p>I wrote the most simple <em>Hello, World!</em> application:</p>
  
  <pre><code>public class Helloworld {
  
      public static void main(String[] args) {
          System.out.println("Hello\nHello");
      }
  }
  </code></pre>
  
  <p>When it runs, the result is:</p>
  
  <pre><code>Hello
  Hello
  </code></pre>
  
  <p>But if I use <code>Hello\nHello</code> as arguments,</p>
  
  <pre><code>public class Helloworld {
  
      public static void main(String[] args) {
          System.out.println(args[0]);
      }
  }
  </code></pre>
  
  <p>the result is <code>Hello\nHello</code>. How do I get the two-line result?</p>
