Java – How to Convert a String to ArrayList
September 20, 2022 - We are splitting the string based on comma (,) as delimiter to get substrings. These substrings are assigned to ArrayList as elements. import java.util.ArrayList; import java.util.List; import java.util.Arrays; public class JavaExample { public static void main(String args[]){ String num = "22,33,44,55,66,77"; String str[] = num.split(","); List<String> al = new ArrayList<String>(); al = Arrays.asList(str); for(String s: al){ System.out.println(s); } } }

You can do the following:
String [] strings = new String [] {"1", "2" };
List<String> stringList = new ArrayList<String>(Arrays.asList(strings)); //new ArrayList is only needed if you absolutely need an ArrayList

Like this :
String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
List<String> wordList = new ArrayList<String>(Arrays.asList(words));
or
List myList = new ArrayList();
String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
Collections.addAll(myList, words);

March 7, 2025 - In this tutorial, we’ll explore how to accomplish this conversion seamlessly using Java’s built-in methods and techniques. An example can help us to understand the problem quickly. Let’s say we have the following ArrayList, which contains some artists’ names: static final List<String> INPUT_LIST = Lists.newArrayList("Michael Bolton", "Michael Jackson", "Guns and Roses", "Bryan Adams", "Air Supply");

In Java 8 or later:
String listString = String.join(", ", list);
In case the list is not of type String, a joining collector can be used:
String listString = list.stream().map(Object::toString)
.collect(Collectors.joining(", "));

If you happen to be doing this on Android, there is a nice utility for this called TextUtils which has a .join(String delimiter, Iterable) method.
List<String> list = new ArrayList<String>();
list.add("Item 1");
list.add("Item 2");
String joined = TextUtils.join(", ", list);
Obviously not much use outside of Android, but figured I'd add it to this thread...

How to split a string into an ArrayList using a delimiter in Java | LabEx
This example demonstrates how to convert a string array to an ArrayList and showcases one of the advantages of using an ArrayList: the ability to easily add new elements to the collection. Note the differences between arrays and ArrayLists: Arrays have a fixed size, while ArrayLists can grow dynamically · ArrayLists provide methods like add(), remove(), and get() for manipulating elements · ArrayLists can only store objects, not primitive types (though Java automatically handles the conversion using autoboxing)
