Convert String into comma separated List in Java
At first, set a list with string values −
List<String> myList = new ArrayList<>( Arrays.asList("One", "Two", "Three", "Four"));
Now, use String.join() to set them as a comma separated list −
String str = String.join(", ", myList);
Example
Following is the program to convert string into comma separated List in Java −
import java.util.*; public class Demo { public static void main(String args[]) { List<String> myList = new ArrayList<>(Arrays.asList("One", "Two", "Three", "Four")); System.out.println("List = " + myList); // comma separated String str = String.join(", ", myList); System.out.println("String (Comma Separated) = " + str); } }
Output
List = [One, Two, Three, Four] Comma separated String: One, Two, Three, Four
