Java基础：数组Array转成List的几种方法

转载自：http://www.oschina.net/code/snippet_8676_2652

 

在编写Java程序中，经常要用的一个转换就是数组和List对象之间的互转
 

[代码] 数组->List (StringArrayTest.java)

view source

 

print?

01	import java.util.Arrays;

02	import java.util.List;

03	import java.util.ArrayList;

04

05	public class StringArrayTest

06

{

07	public static void main(String[] args)

08

{

09	String[] words = {"ace", "boom", "crew", "dog", "eon"};

10

11	List<String> wordList = Arrays.asList(words);

12

13

14	for (String e : wordList)

15

{

16	System.out.println(e);

17

}

18

}

19

}

 

 

[代码] 比较傻的做法

String[] words = { ... }; 
List<String> list = new ArrayList<String>(words.length); 
for (String s : words) { 
    list.add(s); 
}

 

 [代码] 这方法也还可以

import java.util.Collections;

List myList = new ArrayList();
String[] myStringArray = new String[] {"Java", "is", "Cool"};
Collections.addAll(myList, myStringArray);

over!
