printing - Print string to a java.io.Console object -

i'm making multi-player game each player has own input/output console on screen. i'm having bit of trouble trying this. don't want every player see other player's in/outputs.

to use analogy, want playeroneconsole.out.println("player 1 string");, instead of system.out.println("player 1 string"); can see player one's stuff.

after reading documentation, i've tried this, not work intended throws nullpointerexception:

public class player {      string myname;     console myconsole;      public player(string name) {         myname = name;         myconsole = system.console();     }       public void taketurn(string playeroptions){         myconsole.writer().print(playeroptions); //this not right.     } } 

i want playeroptions print exclusively player's console, not system console.

by way, i'm using netbeans ide 8.0.2 if makes difference.

when using java.io.console, must execute java app console e.g. windows cmd or linux terminal. ides won't execute java through console, system#console returns null.

by way, code:

myconsole.writer().print(playeroptions); //this not right. 

it's right indeed :)
