Arraylist new line

Hey, i did an code what loops all players on server and adding them to my arraylist, when i show my arraylist iin command all players are on 1 line [NICK, NICK, NICK] what i must to do to create new line each player? like:
NICK
NICK
NICK

 

Code:java

public String getListAsString(List<?> items, String delimiter) {
    boolean first = true;
    StringBuilder sb = new StringBuilder();
    for (String s : items) {
        if (first) {
            first = false;
        } else {
            sb.append(delimiter);
        }
        sb.append(s.toString());
    }
    return sb.toString();
}

Then you can call:

Code:java

List<String> players; //your list of player names
String playerList = getListAsString(players, ", ");

Alternatively, with Java 8:

Code:java

public String getListAsString(List<?> items, String delimiter) {
    boolean first = true;
    StringBuilder sb = new StringBuilder();
    items.stream().forEach((s) -> {
        if (first) {
            first = false;
        } else {
            sb.append(delimiter);
        }
        sb.append(s.toString());
    });
    return sb.toString();
}

 

You could make a for loop for all the objects their strings and display those on a new line.

}

is that good?

Uh, nope.

What are you attempting to achieve? Sending a joining player a list of online players? Also, try to keep your spacing consistent.
