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...

May 31, 2025 - Collectors.joining - Works with Java Streams for advanced list processing. StringBuilder - Best for performance in large string concatenations. 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:

Convert an ArrayList of Object to an ArrayList of String Elements | Baeldung
March 7, 2025 - We can leverage the Java Streams API to solve our problem as well. We first convert the inputList, our data source, to a stream by applying the stream() method. Once we have a stream of elements, which are of type Object, we need an intermediate operation, which in our case is to do the object-to-string conversion, and finally, a terminal operation, which is to collect the results into another list of type String.

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.

Turning a Java List into a Comma-Separated String | Medium
June 20, 2025 - That pattern works well when you don’t have access to an index or don’t want to deal with list size. StringBuilder holds its data in a plain character array. When you call append, it copies new characters into that array. If the array fills up, StringBuilder allocates a new larger one and copies everything over. This avoids constant object churn like String does with +. Calling toString() gives you a fresh String copy of everything that was added. That final step turns the mutable character data into the fixed String object Java uses everywhere else.
