title: Performance considerations for keySet() and entrySet() of Map
body: <p>All,</p>
  
  <p>Can anyone please let me know exactly what are the performance issues between the 2? The site : <a href="http://www.coderanch.com/t/203203/Performance/java/entrySet-keySet-Map" rel="noreferrer">CodeRanch</a> provides a brief overview of the internal calls that would be needed when using keySet() and get(). But it would be great if anyone can provide exact details about the flow when keySet() and get() methods are used. This would help me understand the performance issues better.</p>
