用于实例化初始化集合的紧凑语法 [英] Compact syntax for instantiating an initializing collection

问题描述

我正在寻找一种紧凑的语法，用于实例化集合并向其中添加一些项目。我目前使用这种语法：

I'm looking for a compact syntax for instantiating a collection and adding a few items to it. I currently use this syntax:

Collection<String> collection = 
    new ArrayList<String>(Arrays.asList(new String[] { "1", "2", "3" }));

我似乎记得有一种更紧凑的方法，它使用<$的匿名子类c $ c> ArrayList ，然后将项目添加到子类的构造函数中。但是，我似乎不记得确切的语法。

I seem to recall that there's a more compact way of doing this that uses an anonymous subclass of ArrayList, then adds the items in the subclass' constructor. However, I can't seem to remember the exact syntax.
