String.join is an easy-to-use utility method in String class.

public class StringJoin{  
    public static void main(String args[]){  
        //The first argument (refered as joinString) is used to join the subsequent argument(s)
        String finalString = String.join("-","String","join","example"," Hyphen(-) used to join");
        System.out.println("Output 1: " + finalString);  
        //In case there is only 1 argument after the first argument, then the second argument is not appended with the joinString
        finalString = String.join("-","String");
        System.out.println("Output 2: " + finalString);  
    }
}
