title: Error Message: Implicit super constructor is undefind for default constructor
body: <p>I'm looking for the cause of an error message &quot;Implicit super constructor is undefind for default constructor......&quot; and can't get any further. The red line is underlying the name of the class test01. The IDE is Visual Studio Code. Can anyone help me? Many thanks.</p>
  <pre><code>public class test01 {
  }
  void main(string args) {
  
      int zahl1, zahl2;
      CKunde Kunde1 = new CKunde(); 
      Cdaten d1 = new Cdaten();
      
  
  }
  </code></pre>
  <p>}</p>
