title: Scala trait - Is there an equivalent of Java interface public static field?
body: <p>In Java:</p>
  
  <pre><code>public interface Foo {
  
    public static final int Bar = 0;
  }
  </code></pre>
  
  <p>And in Scala, how can I create a <code>trait Foo</code> that has <code>Bar</code>, and I can access it as: <code>Foo.Bar</code>?</p>
