Java String Array To List Example
This Java String Array To List Example shows how to convert Java String array to java.util.List object
using Arrays.asList method.

public class JavaStringArrayToListExample {
public static void main(String args[]){
//create String array
String[] numbers = new String[]{"one", "two", "three"};
/*
* To covert String array to java.util.List object, use
* List asList(String[] strArray) method of Arrays class.
*/
List list = (List) Arrays.asList(numbers);
//display elements of List
System.out.println("String array converted to List");
for(int i=0; i < list.size(); i++){
System.out.println(list.get(i));
}
/*
* Please note that list object created this way can not be modified.
* Any attempt to call add or delete method would throw UnsupportedOperationException exception.
*
* If you want modifiable list object, then use
*
* ArrayList list = (ArrayList) Arrays.asList(numbers);
*/
/* Alternate Method to covert String array to List */
List anotherList = new ArrayList();
Collections.addAll(anotherList, numbers);
}
}
/*
Output of this example would be
String array converted to List
one
two
three
