POWill this ever result in a stack overflow error?

copied!<p>Will incrementing the instance variables of an object ever lead to a stack overflow error? </p> <p>For example: </p> <p>This method (java) will cause a stack overflow error: </p> <pre><code>class StackOverflow { public static void StackOverflow (int x) { System.out.println (x) ; StackOverflow(x+1) ; } public static void main (String[]arg) { StackOverflow (0) ; } </code></pre> <p>but will this?: (..... is a gap that i've put in to shorten the code. its long enough as it is.) </p> <pre><code>import java.util.*; class Dice { String name ; int x ; int[] sum ; </code></pre> <p>....</p> <pre><code>public Dice (String name) { this.name = name ; this.x = 0 ; this.sum = new int[7] ; } </code></pre> <p>....</p> <pre><code>public static void main (String[] arg) { Dice a1 = new Dice ("a1") ; for (int i = 0; i<6000000; i++) { a1.roll () ; printDice(a1) ; } } </code></pre> <p>....</p> <pre><code> public void roll () { this.x = randNum(1, this.sum.length) ; this.sum[x] ++ ; } public static int randNum (int a, int b) { Random random = new Random() ; int c = (b-a) ; int randomNumber = ((random.nextInt(c)) + a) ; return randomNumber ; } public static void printDice (Dice Dice) { System.out.println (Dice.name) ; System.out.println ("value: "+Dice.x) ; printValues (Dice) ; } public static void printValues (Dice Dice) { for (int i = 0; i<Dice.sum.length; i++) System.out.println ("#of "+i+"'s: "+Dice.sum[i]) ; } } </code></pre> <p>The above doesn't currently cause a stack overflow error but could i get it too if i changed this line in main: <code>for (int i = 0; i<6000000; i++)</code> so that instead of 6 million something sufficiently high were there? </p>
