Thread: Help with loop problem

I have made a game which works fine, 1 hiccup though, at the start of the game a player is asked whether he wants to be a 0 or a X ( noughts and crosses game)..

my problem is, if i get the player to enter 0 he is automatically set to player 2 ( and X is always player 1)....

then it asked player 2 to input there name... but then it doesnt ask player 1 for there name....

and vis versa if i input X it will go to player 1, i enter the name but it skips player 2 and goes in to the game calling player 2 "null"

my code is

if (userinput.equals ("x") {

bufferReader

Print please enter player 1's name....

and so on

with a try and catch in here...

}

else if (userinput != "X"){

print please enter player 2's name

and so on..

with a try and catch in here...

}

im sure there is an easy solution to this but my mind is frazzled at the moment and i need some guidance...

yes, basically i want it to ask for both players name, just that i need to ask whether the player wants to be a 0 or a X

my code currently asks for both names, but when i add in the code for adding a 0 or being a X im unsure which loop to use, if its a loop, ive done a if, statement but thats just 1 or the other, therefore i only get 1 name as the result and the other is always set to "null" which i dont want....

System.out.println("Do you want to be a 0 or a X???");
String userinput = input.nextLine();

if (userinput.equals ("X")){




BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));
System.out.println("Please enter Player 1's name: ");

try {
player1 = reader.readLine();
} catch (IOException e1) {
e1.printStackTrace();
}

System.out.println("You entered : " + player1 + " as Player 1");
}

else if (userinput != "X"){

BufferedReader reader1 = new BufferedReader(new InputStreamReader(
System.in));
System.out.println("Please enter Player 2's name");

try {
player2 = reader1.readLine();
} catch (IOException e) {
e.printStackTrace();
}
}

thats the code i tried using but it doesnt work....

Ah nice one thanks for the tag help.....

i dont understand, why would i ask for the variable if its null?

player 2 is always 0
player 1 is always X

so shouldnt there be some code that asks

print do you want to be a nought or a cross

if nought assign player 2

else assign player 1

but then i also want it to ask both players for names, this is the part where im struggling, i can get both to work separately, but asking for which 0 or X and what name u want im having real trouble with,

thanks for your assistance! means a lot!
