在java开发中,collection和collections有什么区别?


在Java开发中,`Collection`和`Collections`是两个不同的概念。 `Collection`是一个接口,它是Java集合框架的基础接口,它定义了一些基本的操作,如添加、删除、查找、排序等。`Collection`接口的实现类包括`List`、`Set`、`Queue`等。 `Collections`是一个类,它是Java集合框架的一部分,它提供了一些静态方法,可以方便地对集合进行操作,如排序、填充、复制等。`Collections`类的静态方法可以操作任何实现了`Collection`接口的集合。 `Collection`和`Collections`的主要区别在于,`Collection`是一个接口,它定义了一些基本的操作,而`Collections`是一个类,它提供了一些静态方法,可以方便地对集合进行操作。 [2023-11-07 22:15:46 | AI小红书种草文 | 165点数解答]
