java - Java中如何定义栈

Question

这个问题已经有答案了:

Best implementation of Java Queue? (9 个回答)

我知道 Java 通过扩展 Vector 搞砸了堆栈实现。默认情况下 vector 是同步的。阅读java文档，它说要创建一个堆栈，

 Deque<Integer> stack = new ArrayDeque<Integer>();

因为我对java比较陌生。我的问题是:这是在 Java 中定义堆栈的最佳实践吗？

Answer 1

阅读Stack的javadoc :

A more complete and consistent set of LIFO stack operations is provided by the Deque interface and its implementations, which should be used in preference to this class. For example:

Deque<Integer> stack = new ArrayDeque<Integer>();

甚至 Deque 的 javadoc 也这么说:

Deques can also be used as LIFO (Last-In-First-Out) stacks. This interface should be used in preference to the legacy Stack class.

遵循 java 文档的建议是“最佳实践”吗？
是的。
