Java基础：数组Array转成List的几种方法

[代码] 数组->List (StringArrayTest.java)

 

import java.util.Arrays;  

 import java.util.List;  

import java.util.ArrayList;  

    public class StringArrayTest  

{  

  public static void main(String[] args)  

    {  

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

     

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

     

      for (String e : wordList)  

     {  

         System.out.println(e);  

     }  

  }  

 

 

[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);
