如何使用Java中的数组初始化向量？ [英] How to initialize a vector with an array in Java?

问题描述

我是否必须逐个推送我的元素？我试过像

Do I have to push my elements one by one? I tried something like

String[] array;
array=...
Vector<String> vector = new Vector<String>(array);

但我的eclipse将此标记为错误。

but my eclipse marks this as an error.

推荐答案

Vector 没有直接接受数组的构造函数。

Vector doesn't have a constructor that accepts an array directly.

假设数组的类型为 String [] ，你可以

Vector<String> vector = new Vector<String>(Arrays.asList(array));

最好使用 ArrayList 因为它没有'具有同步方法的开销。你可以使用

Better to use ArrayList as it doesn't have the overhead of having synchronized methods. You could use

List<String> list = new ArrayList<>(Arrays.asList(array));

这也将产生一个可变集合。

This will produce a mutable collection also.
