本文实例讲述了Java使用Deque实现堆栈的方法。分享给大家供大家参考。具体如下：
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); } } /* 输出 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] */
希望本文所述对大家的java程序设计有所帮助。
