How to delete last , ?

import java.util.ArrayList;

public class List {
   public static void main (String[] args) {
       ArrayList<String> companies = new ArrayList<>();
        companies.add("DELL");
        companies.add("APPLE");
        companies.add("SAMSUNG");
        companies.add("SONY");
        companies.add("ALCATEL");
         for (int i = 0; i < companies.size(); i++) {
      System.out.print(companies.get(i)+ ", " );
         }
   }
}

I want to delete last , from list output should be : DELL, APPLE, SAMSUNG, SONY, ALCATEL not : DELL, APPLE, SAMSUNG, SONY, ALCATEL,

System.out.println(String.join(", ", companies));

There are various approches to output a list with a delimiter using a loop... eg.:

StringBuilder sb = new StringBuilder();
if (companies.size() > 0) {
    sb.append(companies.get(0));
    for (int i = 1; i < companies.size(); i++) {
        sb.append(", ").append(companies.get(i));
    }
}
System.out.println(sb.toString());
