title: Removing, Searching, and Returning a position using Type T
body: <p>Need help defining these methods, I am not familiar using Type T.  </p>
  
  <p>Define the following two methods in the <code>LinkedList</code> class:</p>
  
  <p>1) The <code>searchItem</code> method takes an item to be search of type T in the list and if it is found then returns the position in the list, otherwise return -1</p>
  
  <p>2) The <code>removeItem</code> method takes as argument an item to be removed of type T and returns true if the item is successfully removed, otherwise returns false.</p>
