title: How to use classes in Referenced Libraries in Eclipse
body: <p>I have imported the algs4.jar file as a referenced library as seen above. All seems to be fine but I can't seem to use or access any of the classes in the library.</p>
  
  <p>Is there an import statement I'm missing?</p>

  <p>Note how I'm trying to use <code>BinarySearch</code> from the referenced library but it is not offering me an option to use or import it.</p>
