在c++于java項(xiàng)目中自定義Troop<T>泛型類達(dá)到方法

發(fā)布時間：2020-11-20 16:28:57 來源：億速云 閱讀：130 作者：Leah 欄目：編程語言

這篇文章給大家介紹在c++于java項(xiàng)目中自定義Troop<T>泛型類達(dá)到方法，內(nèi)容非常詳細(xì)，感興趣的小伙伴們可以參考借鑒，希望對大家能有所幫助。

Troop<T>是一個泛型列表操作類，適用于非高性能和非大數(shù)據(jù)量的要求。包括了：取值get，賦值set，追加append，插入insert，清除remove，進(jìn)隊(duì)enqueue，出隊(duì)dequeue，交換swap，滾動roll，進(jìn)棧push，出棧pop等日常操作。
