// Java program for joining the strings
// Using StringJoiner class
  
import java.io.*;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.StringJoiner;
  
class GFG {
    public static void main(String[] args)
    {
        // Here we need to join strings "DSA","FAANG","ALGO"
        // and with delimiter " gfg "
        StringJoiner sj
            = new StringJoiner(" gfg ", "[", "]");
        
        sj.add("DSA");
        sj.add("FAANG");
        sj.add("ALGO");
        
        // Convert StringJoiner to String
        String joined = sj.toString();
  
        // Here we created an ArrayList of strings
        ArrayList<String> gfgstrings = new ArrayList<>(
            Arrays.asList("DSA", "FAANG", "ALGO"));
        
        // StringJoiner class having parameters
        // delimiter,prefix,suffix
        StringJoiner sj2
            = new StringJoiner(" gfg ", "[", "]");
        
        // Now we will iterate over ArrayList
        // and adding in string Joiner class
        for (String arl : gfgstrings) {
            sj2.add(arl);
        }
        
        // convert StringJoiner object to String
        String joined2 = sj2.toString();
  
        // printing the first output
        System.out.println(joined);
        System.out.println("--------------------");
        
        // printing the second output
        System.out.println(joined2);
    }
