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...

No. It doesn’t quite, you’re starting with your solution instead of the problem. Are you trying to remove initial/number from params? If so, my hint is that you can’t “edit” strings, so you need to do something with params to make this easier. Then rebuild the string when you’re done. More on reddit.com

StringJoiner - Useful for structured output with prefixes and suffixes. Manual string concatenation (loops) - A traditional approach, but less efficient. By choosing the right method, you can optimize performance and readability based on your specific use case. The simplest way to join list elements with a delimiter:

Another idea is to use the Apache Commons Lang to write the following code:
StringUtils.join(myList);
The interest is that you also can provide a separator, for example:
StringUtils.join(myList, " ; ");

Providing you don't object to the string output following the convention:
[A, B, C]
... you can simply call the List'stoString() method to obtain your output (I'm not sure why people are advocating using a loop for this). It may also be sensible to override Car's toString() method to return a human-friendly description of the object.
However, if you wish to obtain each element as an individual String you will need to iterate over the List one element at a time.

Logging: When logging a list of values, it's more convenient to convert the list to a string and log the string rather than logging each element separately. Displaying data: In a user interface, you might need to display a list of items as a single line of text. Sending data over a network: If you're sending data from one system to another, it's often easier to send a single string rather than a list. import java.util.ArrayList; import java.util.List; public class ListToStringForLoop { public static void main(String[] args) { List<String> list = new ArrayList<>(); list.add("apple"); list.add("banana"); list.add("cherry"); String result = ""; for (int i = 0; i < list.size(); i++) { if (i > 0) { result += ", "; } result += list.get(i); } System.out.println(result); } }

You have to loop through the list and fill your String[].
String[] array = new String[lst.size()];
int index = 0;
for (Object value : lst) {
array[index] = (String) value;
index++;
}
If the list would be of String values, List then this would be as simple as calling lst.toArray(new String[0]);

You could use toArray() to convert into an array of Objects followed by this method to convert the array of Objects into an array of Strings:
Object[] objectArray = lst.toArray();
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);
