本文實例講述了Java使用Deque實現堆棧的方法。分享給大家供大家參考。具體如下：

				?

									import java.util.ArrayDeque;

									import java.util.Deque;

									public class IntegerStack {

									 private Deque<Integer> data = new ArrayDeque<Integer>();

									 public void push(Integer element) {

									  data.addFirst(element);

									 }

									 public Integer pop() {

									  return data.removeFirst();

									 }

									 public Integer peek() {

									  return data.peekFirst();

									 }

									 public String toString() {

									  return data.toString();

									 }

									 public static void main(String[] args) {

									  IntegerStack stack = new IntegerStack();

									  for (int i = 0; i < 5; i++) {

									   stack.push(i);

									  }

									  System.out.println("After pushing 5 elements: " + stack);

									  int m = stack.pop();

									  System.out.println("Popped element = " + m);

									  System.out.println("After popping 1 element : " + stack);

									  int n = stack.peek();

									  System.out.println("Peeked element = " + n);

									  System.out.println("After peeking 1 element : " + stack);

									 }

									}

									/* 輸出

									After pushing 5 elements: [4, 3, 2, 1, 0]

									Popped element = 4

									After popping 1 element : [3, 2, 1, 0]

									Peeked element = 3

									After peeking 1 element : [3, 2, 1, 0]
