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 = 4After popping 1 element : [3, 2, 1, 0]Peeked element = 3After peeking 1 element : [3, 2, 1, 0]*/希望本文所述對大家的java程序設計有所幫助。
