用于可比较对象列表的Java语法 [英] Java Syntax for a list of comparable objects

问题描述

我正在编写一个方法，它将唯一参数作为可比较对象的列表，并且不返回任何内容。我不确定它应具有的语法：

I'm writing a method that takes as its only parameter a list of comparable objects and doesn't return anything. I am uncertain as to the syntax that it should have:

public static void methodName(List<Comparable<Object>> list) {
    // Do some stuff
}

我认为这是错误的因为< Object> 作为Comparable的类型，这意味着列表可以将整数和布尔值作为对象，但我不希望这样。我希望列表只采用一种类型，但该类型必须实现Comparable接口。我如何实现这一目标？

I think this is wrong because of the <Object> as a type for Comparable, which would mean the list can take an Integer and a Boolean as objects, but I don't want that. I want the list to take only one type, but that type has to implement the Comparable interface. How do I achieve that?

推荐答案

也许让它变得通用？

public static <E extends Comparable<E>> void methodName(List<E> list) ...
