A TeamUserPlayer is a Player, but a Player is not a TeamUserPlayer.

You must create a class implementing TeamUserPlayer

Code:

class MyTeamUserPlayer implements TeamUserPlayer {
 
Player player;
 
MyTeamUserPlayer(Player p) {
this player = p;
}
}

Implement the methods of the TeamUserPlayer interface in this class.

Then you can execute your code :

Code:

TeamUserPlayer player = new MyTeamUserPlayer(s);
player.setTeam(true);
player.sendMessage("test");
