Can anyone see why this is displaying all zeroes?

[jubbiejub]

I am working on a Dice Roll simulator. For some reason in my DiceTester class (the class I'm using to roll the dice and report what I find), the numbers aren't going into the array like I expect them to. Anybody see the problem?

public class DiceTester{
		
		int x;
		Dice dice;
	
		
	//Initializes Dice roll totals and doubles
	
		int[] diceTotalList = new int[13];
		int[] doubleList = new int[7];
	
	
	
	//runs a test for "n" rolls of the dice.
	
	public void runTest(int n){
		 
		 for(int a = 0; a > n ; ++a){
			 
			 int diceRoll = dice.rollDice();
			 int doubleRoll = dice.doubles();
			 
			 for(int x = 0; x > n; ++x){	
				 
				 if(diceRoll == 2 && doubleRoll == 0){
					 ++diceTotalList[2]; 
				 }
				 else if(diceRoll == 3 && doubleRoll == 0){
					 ++diceTotalList[3]; 
				 }
				 else if(diceRoll == 4 && doubleRoll == 0){
				 	 ++diceTotalList[4]; 
				 }
				 else if(diceRoll == 5 && doubleRoll == 0){
				 	 ++diceTotalList[5]; 
				 }
				 else if(diceRoll == 6 && doubleRoll == 0){
				 	 ++diceTotalList[6]; 
				 }
				 else if(diceRoll == 7 && doubleRoll == 0){
				 	 ++diceTotalList[7]; 
				 }
				 else if(diceRoll == 8 && doubleRoll == 0){
				 	 ++diceTotalList[8]; 
				 }
				 else if(diceRoll == 9 && doubleRoll == 0){
				     ++diceTotalList[9]; 
				 }
				 else if(diceRoll == 10 && doubleRoll == 0){
				 	 ++diceTotalList[10]; 
				 }
				 else if(diceRoll == 11 && doubleRoll == 0){
					 ++diceTotalList[11]; 
				 }
				 else if(diceRoll == 12 && doubleRoll == 0){
					 ++diceTotalList[12]; 
				 }
				 else if(diceRoll == 13 && doubleRoll == 0){
					 ++diceTotalList[13]; 
				 }
				 else{
					 	if(doubleRoll == 1){
					 		++doubleList[1];
					 	  }
					 	else if(doubleRoll == 2){
					 		++doubleList[2];
					 	  }
					 	else if(doubleRoll == 3){
					 		++doubleList[3];
					 	  }
					 	else if(doubleRoll == 4){
					 		++doubleList[2];
					 	  }
					 	else if(doubleRoll == 5){
					 		++doubleList[5];
					 	  }
					 	else if(doubleRoll == 6){
					 		++doubleList[6];
					 	  }
			  
					 }
			 }
		 }
	} //end of runTest
	
	
	
	public void report(){
		
		System.out.printf("The number 2 was rolled %d times.\n", diceTotalList[2]);
		System.out.printf("The number 3 was rolled %d times.\n", diceTotalList[3]);
		System.out.printf("The number 4 was rolled %d times.\n", diceTotalList[4]);
		System.out.printf("The number 5 was rolled %d times.\n", diceTotalList[5]);
		System.out.printf("The number 6 was rolled %d times.\n", diceTotalList[6]);
		System.out.printf("Doubles were rolled %d times\n", doubleList[1] + doubleList[2] + doubleList[3] + doubleList[4] + doubleList[5] + doubleList[6]);
	
		}
	
	
//}

public static void main(String[] args){
	
	DiceTester diceTester = new DiceTester();
	diceTester.runTest(100000);
	diceTester.report();

	}
}

The problem may be in the code you've not shown us, the Dice class.

[eRaaaa]

1. u never create a dice object!
2. your for loops-conditions are wrong - read a book
for(int a = 0; a > n ; ++a){
->
for(int a = 0; a < n; ++a){
The same here for(int x = 0; x > n; ++x){
(and the declared x in the class header is unused now!)
3. the whole if statements are unnecessary!
++diceTotalList[diceRoll];

I had noticed and fixed all the other errors before I looked at your comment, but I now understand why I should use ++diceTotalList[diceRoll] instead and my counters work perfectly. Thanks!
