I am fairly new to the java platform. I have just installed it and done everything that i know to do. As far as i know everything is right. I was putting in a program from the new HEAD FIRST java book, which is exceptionally well written might i add, however when i put in the code my computer isnt recognizing the dot operator and some other interesting parts of what i would call a pretty simple program. Please help, i want to make sure i am doing everything right. To give you a good idea what is going on: I have installed j2sdk1.4.2_03 and changed my path name and i have even written a simple hello world program. So i knnow that everything is working ok. I am thinking i am missing a plug in or have a file in the wrong direstory, but i still don't really know. Please help!!

everywhere <<<< is where the error is given to me.
public class GuessGame {
Player p1;
Player p2;
Player p3;
public void startgame() {
p1 = new Player();
p2 = new Player();
p3 = new Player();
int guess1 = 0;
int guess2 = 0;
int guess3 = 0;
boolean p1isRight = false;
boolean p2isRight = false;
boolean p3isRight = false;
int targetNumber = (int) (Math.random() * 10);
System.out.println("I'm thinking of a number between 0 and 9...");
while(true) {
System.out.println("Number to guess is " + targetNumber);
guessp1 = p1.number;
System.out.println("Player one guessed " + guessp1); <<<<<
guessp2 = p2.number;
System.out.println("Player two guessed " + guessp2); <<<<<
guessp3 = p3.number;
System.out.println("Player three guessed " + guessp3); <<<<<

if (guessp1 == targetNumber) { <<<<<
p1isRight = true;
if (guessp2 == targetNumber) { <<<<<
p2isRight = true;
if (guessp3 == targetNumber) { <<<<<
p3isRight = true;
if (p1isRight || p2isRight || p3isRight) {
System.out.println("We have a winner!");
System.out.println("Player one got it right?" + p1isRight);
System.out.println("Player two got it right?" + p2isRight);
System.out.println("Player three got it right?" + p3isRight);
System.out.println("Game is over");
} else {

System.out.println("Players will have to try again.");

there are others but ive forgotten how to look page by page in dos...oopsie.

Unless I'm mistaken, you want your variable guessp1 to be guess1 as you defined earlier in the file, no? Same with the other two files.

Thank you. everything is good with that class. But i still have problems with the dot operator, in a another portion of the program, in this class below:
public class GameLauncher {
public static void main (String[] args) {
GuessGame game = new GuessGame();
game.startGame(); <<<<< here it doesnt like the dot

is there more i can do???
