title: Java: LinkedList class as stack and queues
body: <p>I am new to LinkedList class, and facing difficulties as to how to use it in order to implement or instantiate stack and queues object. I am not looking for piece of self-implemented codes.</p>
  
  <p>I wanted to know how do we use this class as stack and queues and can use the already defined methods: pop,push,enqueue and dequeue or top (in case of stacks).</p>
