title: Rename multiple files in eclipse
body: <p>How can I rename multiple files in eclipse and update their references as well ? </p>
  
  <p>For ex. I got these classes in many packages in my project : </p>
  
  <pre><code>com.a.b.c.Fooclass1
  com.a.b.c.Fooclass2 
  com.a.b.c.Fooclass3
  com.a.b.c.BarFooclass1
  com.a.b.c.Dontworryclass
  </code></pre>
  
  <p>I want to replace <code>Foo</code> with <code>BAR</code>.<br/>
  How can I replace <code>Foo</code> with <code>BAR</code> in the class names of all those classes in my project, which have <code>Foo</code> in their name. </p>
  
  <p><strong>Edit</strong> : I <em>really know</em> how to use refactor in eclipse for a single file ! I wanted to know a solution for multiple files. </p>
