title: Is there any "visual debugger" for Java?
body: <p>Is there any debugger for Java that shows step-by-step animation of what actually happens when some lines of codes are run?</p>
  
  <p>My friend is asking a lot of Java questions and I'm not sure about the communication right now...</p>
  
  <p>(I'm not even sure about what I'm saying T.T)</p>
  
  <p>Thank you!</p>

  <p>I think the question is not so clear to everyone here...</p>
  
  <p>I don't want ANY debugger here - I already know about eclipse's debugger and etc.</p>
  
  <p>I'm wondering whether anyone made a debugger that shows PICTURES and animations...</p>
  
  <p>I'm trying to teach a guy and thought it would be really good to have a tool that can explain things graphically.</p>
  
  <p>(eclipse debugger - it's all about text. I don't think it's very effective when it comes to teaching things like recursion.)</p>
