Java string join arraylist

// You can't just do String.join(", ", list) because
// the list has to be a String[]. This code works on
// everything.

list.stream().map(Object::toString).collect(Collectors.joining(", "));

Java join list as string

List<String> list = Arrays.asList("a","b","c");
String result = String.join(",", list);

System.out.println(result);		//prints a,b,c
