One efficient method for converting an ArrayList to a String in Java is to use the built-in String.join() method with a delimiter. For example:

ArrayList<String> list = new ArrayList<String>();
String string = String.join(", ", list);

This will create a string that concatenates all the elements in the ArrayList separated by the delimiter ", ". In this example, the resulting string would be "Hello, World".
