Joining Strings using String.join() Example

In this Java example, we join strings with the String.join() method.

public class Java8StringJoinExample {

    public static void main(String[] args) {

        String join = String.join("/", "2019", "07", "11");
        System.out.println(join);
    }
}

Output:

2019/07/11

The String.join() method internally uses the StringJoiner.

A date is concatenated with the String.join() method:

String join = String.join("/", "2019", "07", "11");
