如果你想要返回两个对象想要返回一个封装两个对象的单个对象。
If you want to return two objects you usually want to return a single object that encapsulates the two objects instead.
你可以返回一个 ListdObject的List / code>这样的对象:
You could return a List of NamedObject
objects like this:
public class NamedObject<T> {
public final String name;
public final T object;
public NamedObject(String name, T object) {
this.name = name;
this.object = object;
}
}
然后你可以轻松返回 List< NamedObject< WhateverTypeYouWant>>
。
另外:为什么要返回以逗号分隔的名称列表而不是列表与LT;字符串>
?或者更好的是,返回 Map< String,TheObjectType>
,其中键是对象的名称和值(除非您的对象具有指定的顺序,在这种情况下为 NavigableMap
可能就是你想要的。
Also: Why would you want to return a comma-separated list of names instead of a List<String>
? Or better yet, return a Map<String,TheObjectType>
with the keys being the names and the values the objects (unless your objects have specified order, in which case a NavigableMap
might be what you want.
