I want to convert String
array to ArrayList
. For example String array is like:
String[] words = new String[]{"ace","boom","crew","dog","eon"};
How to convert this String array to ArrayList?
This question is related to
java
new ArrayList( Arrays.asList( new String[]{"abc", "def"} ) );
Using Collections#addAll()
String[] words = {"ace","boom","crew","dog","eon"};
List<String> arrayList = new ArrayList<>();
Collections.addAll(arrayList, words);
String[] words= new String[]{"ace","boom","crew","dog","eon"};
List<String> wordList = Arrays.asList(words);
in most cases the List<String>
should be enough. No need to create an ArrayList
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
...
String[] words={"ace","boom","crew","dog","eon"};
List<String> l = Arrays.<String>asList(words);
// if List<String> isnt specific enough:
ArrayList<String> al = new ArrayList<String>(l);
