title: implicit super constructor Person() is undefined. Must explicitly invoke another constructor?
body: <p>I am working on a project and i am getting the error "implicit super constructor Person() is undefined. Must explicitly invoke another constructor" and i don't quite understand it.</p>
  
  <p>Here is my person class:</p>
  
  <pre><code>public class Person {
      public Person(String name, double DOB){
  
      }
  }
  </code></pre>
  
  <p>And my student class when trying to implement the person class, and giving it an instructor variable.</p>
  
  <pre><code>public class Student extends Person {
  
      public Student(String Instructor) {
  
      }
  
  }
  </code></pre>
