ArrayList 初始化等价于数组初始化 [英] ArrayList initialization equivalent to array initialization

问题描述

我知道你可以在实例化过程中初始化一个数组，如下所示:

I am aware that you can initialize an array during instantiation as follows:

String[] names = new String[] {"Ryan", "Julie", "Bob"};

有没有办法用 ArrayList 做同样的事情?还是我必须使用 array.add() 单独添加内容?

Is there a way to do the same thing with an ArrayList? Or must I add the contents individually with array.add()?

推荐答案

Arrays.asList 可以在这里提供帮助:

Arrays.asList can help here:

new ArrayList<Integer>(Arrays.asList(1,2,3,5,8,13,21));
