One of the easiest methods is to use the toString method which follows List
private void OutString() { List<Integer> integerList = Arrays.asList(1,2,34,6); System.out.println(integerList); }
Output:
[1, 2, 34, 6]
ToString method used herein is the List elements, used in the examples is of type integer, it toString () method.
If we are to use their own definitions, such as "Person", then pay attention to "Person" class must override the toString method returns otherwise there will be problems like this
