title: Interview : Is it possible to create a class without name?
body: <p>During my interview, interviewer asked me </p>
  
  <p><em>Can we create class without name ?</em> </p>
  
  <p>Since, I was not sure, if it is really possible to create a class without name. So, I said <strong>No</strong>. </p>
  
  <p>Later,  I tried Googling and found, others are also looking for the answer of the same question, but I didn't found clear answer.</p>
  
  <p>I will appreciate, if anyone clearly explain about this class. I mean, what that class technically known as and how can we instantiate this class ?</p>
