Can someone fix this code for me so that I dont have to do size + 1 and queue = new String[6] in the contructors to get the result I want? It works but only when I do this and id like the constructors to stay the same but I cant figure out where I messed up. Whenever it shows a full queue it shows it as empty when using both constructors.

public class MinimalQueue {

String queue[];

int front = -1;

int back = -1;

public MinimalQueue(){ queue = new String[5]; } public MinimalQueue(int size) {

queue = new String[size];

}

public void enqueue(String element) {

back = (back + 1) % queue.length;

queue[back] = element;

if (front == -1) { front = 0; }

}

public String dequeue() {

String element = queue[front];

queue[front] = null;

if (front == back) { front = back = -1; } else { front = (front + 1) % queue.length; }

return element;

}

public boolean isFull() {

return back == queue.length - 1;

} public boolean isEmpty() {

return front == -1;

}

public void showQueue() {

for (int i = front; i <= back; i++) { System.out.print(queue[i] + " "); } System.out.println();

}

}
