This is were you use = + 

Conditinals are what are used to make a string work.

public interface Queue<E> extends Collection<E> {

    E element();

    boolean offer(E e);

    E peek();

    E poll();

    E remove();

}

List: If you just want a list and don't care about any duplicates, i.e list of people, shopping list, list of things to do in life.

​

Queues: If you want to simulate a queue for example, in a hospital you have a queue and also priority queue (in emergency departments). The triage would determine who is in critical condition and needs to be treated.

​

Another example is a shopping queue, first person in line is 'usually' the first one to checkout.

​

Stacks: Used in your internal memory to push and pop values as you pass them to functions/methods.

​

Another interesting use is, in video game inventory method, where you can pick up an item (push) onto the stack, and drop an item (pop) off the stack.

​

Hash/Dictionary: These are usually seen used in database, for look up and index.

​

Depending on what you want to simulate, I do agree with the others, it's handy to read up on data-structures. A book helps but the internet also has a wealth of information.
