Java get a group of user names

I've coded a program where there is like 5 people "killing" a monster, and i need a piece of code to get all of the me开发者_运维技巧mbers "nickname" (getName() ) and display them with a coma beetwen, how could I do that?

I guess I could do a for loop but ye, not sure how to add the comas beetwen then..

Assuming your players are in a collection, you can indeed use a loop, or you can use some 3rd party library, like guava:

Joiner.on(',').join(players);

Or commons-lang:

StringUtils.join(players, ',');

Well, what you do in your loop depends on the way you have this information stored and the structure you are using for things...

But an example would be:

 String namesList = "";
    for(int i = 0; i != 5; ++i){
        String name = users[i].getName()
        namesList += name;
        namesList += ", ";
        ... //do something else
    }

Or if you can use Google Guava (highly recommended as a tool in your belt anyway):

String nickname = Joiner.on(",").join(listOfMembers);
