Answer #1
  • This interface is a prameterized one. It is public and has three method prototypes:
    • 1.) public method with boolean return type: isEmpty
    • 2.) public method with T return type: deque
    • 3.) public method with no return and T as argument: enque

interface implementation:

interface QueueInterface<T>{

public boolean isEmpty();

public T dequeue();

public void enqueue(T element);

}
