main java

Step 4 Develop a class with only a main method in it: public class QueueDemot public static void main(String[] args) { Inside of this main method do the following: Create a reference to a Queue Interface<String> called myQueue and have it refer to a new object of the ImprovedQueue<String> class Call the enqueue method on myQueue passing the String value of "A" Call the enqueue method on myQueue passing the String value of "B" Call the enqueue method on myQueue passing the String value of "C" Call the enqueue method on myQueue passing the String value of "D" Create a String variable called discard and sets it value to the value that is returned from a call to dequeue on myQueue Set the value of discard to the value that is returned from a call to de queue on myQueue Create a loop that continues as long as the queue is not empty and inside this loop create a variable called front that is set each time through the loop to the value that is returned from a call to de queue on my Queue and then the value of front is printed each time through the loop */

Answer 1

public class Main {
    public static void main(String args[]) {
        QueueInterface<String> myQueue = new ImprovedQueue<String>();

        myQueue.enqueue("A");
        myQueue.enqueue("B");
        myQueue.enqueue("C");
        myQueue.enqueue("D");

        String discard = myQueue.dequeue();

        while(!myQueue.isEmpty()) {
            String front = myQueue.dequeue();
            System.out.println("Front = " + front);
        }
    }
}
