title: " If the parent has no constructor (Object does have one), the compiler will reject the program."
body: <p>Hi I was reading <a href="https://docs.oracle.com/javase/tutorial/java/javaOO/objectcreation.html" rel="nofollow noreferrer">Object declaration</a>, and encountered the statement</p>
  <blockquote>
  <p>If the parent has no constructor (Object does have one), the
  compiler will reject the program.</p>
  </blockquote>
  <p>Does any one have any idea what this means?</p>
