title: Eclipse Java Project Error
body: <p>I created a new project in Eclipse called Lottery. The first thing that happened was I recieved a weird icon on my project that I never seen before.

  <p>I decided it was nothing and created a new class, called RandomNumberGenerator. Then it gave me the following error:</p>
  
  <pre><code>Implicit super constructor Object() is undefined for default constructor. 
  Must define an explicit constructor
  </code></pre>
  
  <p>I have no idea what the problem is. Could somebody help? I can't create another class without an error!</p>
  
  <p>Thanks in advance!</p>
