title: What are the big improvements between guava and apache equivalent libraries?
body: <p>We currently use apache collections, string utils, etc. I need to decide if we should switch from the apache foundations implementation.</p>
  
  <p>The important criteria is ease of developers use. Performance/memory usage is not yet an important issue for us. Speed of development is the key criteria at this point.</p>
  
  <p>I would appreciate opinions about how the developer's life became significantly easier with guava.</p>
