How to convert comma-separated String to List?

Question

Is there any built-in method in Java which allows us to convert comma separated String to some container (e.g array, List or Vector)? Or do I need to write custom code for t

Answer 1

There is no built-in method for this but you can simply use split() method in this.

String commaSeparated = "item1 , item2 , item3";
ArrayList<String> items = 
new  ArrayList<String>(Arrays.asList(commaSeparated.split(",")));

Answer 2

This code will help,

String myStr = "item1,item2,item3";
List myList = Arrays.asList(myStr.split(","));

Answer 3

List<String> items= Stream.of(commaSeparated.split(","))
     .map(String::trim)
     .collect(toList());

Answer 4

An example using Collections.

import java.util.Collections;
 ...
String commaSeparated = "item1 , item2 , item3";
ArrayList<String> items = new ArrayList<>();
Collections.addAll(items, commaSeparated.split("\\s*,\\s*"));
 ...

Answer 5

List commaseperated = new ArrayList();
String mylist = "item1 , item2 , item3";
mylist = Arrays.asList(myStr.trim().split(" , "));

// enter code here

Answer 6

List<String> items = Arrays.asList(s.split("[,\\s]+"));
