Javaコード
import java.util.ArrayDeque;
import java.util.Deque;

public class ArrayDequePopDemo {

public static void main(String[] args) {
// create an empty array deque with an initial capacity
Deque<Integer> deque = new ArrayDeque<Integer>(8);

// use add() method to add elements in the deque
deque.add(15);
deque.add(23);
deque.add(36);
deque.add(45);

// printing all the elements available in deque
for (Integer number : deque) {
System.out.println(“Number = " + number);
}

int retval = deque.pop();
System.out.println(“Element removed is " + retval);

// printing all the elements available in deque after using pop()
for (Integer number : deque) {
System.out.println(“Number = " + number);
}
}
}
結果
Number = 15
Number = 23
Number = 36
Number = 45
Element removed is 15
Number = 23
Number = 36
Number = 45
