包路径：java.util.Arrays
类名称：Arrays
方法名：asList

Arrays.asList介绍

[英]Returns a List of the objects in the specified array. The size of the List cannot be modified, i.e. adding and removing are unsupported, but the elements can be set. Setting an element modifies the underlying array.
[中]返回指定数组中对象的列表。无法修改列表的大小，即不支持添加和删除，但可以设置元素。设置元素会修改基础数组。

private void usingArrayList() {
 ArrayList<String> list = new ArrayList<>(Arrays.asList("cat", "cow", "dog"));
 list.add("fish");
 int size = list.size(); // size = 4
 list.set(size - 1, "horse"); // replacing the last element to "horse"
 String removed = list.remove(1); // removed = "cow"
 String second = list.get(1); // second = "dog"
}
