Kotlin constructor with super class
<p>Any way I try, be it primary constructors or secondary, I can't figure out how to declare a new class with a super class and a constructor in kotlin.</p>

<pre><code>class myPanel : JPanel {
    myPanel() : super() {

    }
}
</code></pre>

<p>This is how i would most like t do it but it gives an error expecting member declaration.</p>

<pre><code>class myPanel() : JPanel() {
    {
        ...
    }
}
</code></pre>

<p>this is how I thought a primary constructor looked but it gives the same error. Searching the internet hasn't been helpful and all I could find was the second example.</p>

<p>So, what are all of the valid ways of creating a class with a super class and its one constructor?</p>
