Java: How to convert String[] to List or Set [duplicate]

Answer 1

The easiest way is through

Arrays.asList(stringArray);

Answer 2

If you really want to use a set:

String[] strArray = {"foo", "foo", "bar"};  
Set<String> mySet = new HashSet<String>(Arrays.asList(strArray));
System.out.println(mySet);

output:

[foo, bar]

Answer 3

java.util.Arrays.asList(new String[]{"a", "b"})

Answer 4

String[] w = {"a", "b", "c", "d", "e"};  

List<String> wL = Arrays.asList(w);  

Answer 5

It's a old code, anyway, try it:

import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;
public class StringArrayTest
{
   public static void main(String[] args)
   {
      String[] words = {"word1", "word2", "word3", "word4", "word5"};

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

      for (String e : wordList)
      {
         System.out.println(e);
      }
    }
}

Answer 6

Arrays.asList() would do the trick here.

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

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

For converting to Set, you can do as below

Set<T> mySet = new HashSet<T>(Arrays.asList(words));
