POJava: Variable holder and its value?
text
Body
copied!<p>I'm having a tough time understanding something from one of my exercises in a book(Complete beginner).</p> <p>The example code was to make a guessing game with three players and it generates a random int for all three players which has to come out the same as the randomly generated int by the game.</p> <p>The code contains three classes, but this is the most important one where I have a question. The other two are just GameLauncher class and Player(The one that plays against the other three players) class.</p> <pre><code>public class GuessGame { Player p1; Player p2; Player p3; public void startGame(){ p1 = new Player(); p2 = new Player(); p3 = new Player(); int guessp1 = 10; int guessp2 = 0; int guessp3 = 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); p1.guess(); p2.guess(); p3.guess(); guessp1 = p1.number; System.out.println("Player one has guessed " + guessp1); guessp2 = p2.number; System.out.println("Player two has guessed " + guessp2); guessp3 = p3.number; System.out.println("Player three has 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("The game is over."); break; }else{ System.out.println("None of you got it right! Try again!"); } } } } </code></pre> <p>From the above code:</p> <pre><code> int guessp1 = 10; int guessp2 = 0; int guessp3 = 0; </code></pre> <p>is the one that I don't understand. Originally, all of them are assigned the value 0. I tried to assign 10 to see what would happen, but nothing changed. The game played out just the same.</p> <p>My question is, what is the significance for the value assigned to a declared integer if any at all? Especially in this situation.</p> <p>Excluding normal uses like say just printing it or manipulating it with math. </p>
