Java使用Deque实现堆栈的方法

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。
