Dice roll program with statistics
It is nice that you have separate methods for throwing the dice and computing the counts. However, diceRoll can be simplified and counters supersimplified; like this

    public static int diceRoll() { 
        Random rand = new Random();
        return rand.nextInt(6) + rand.nextInt(6) + 2;
    }

    public static int[] counters(int[] arr) { 
        int[] counterArray = new int[11];

        for (int dice : arr) {
            counterArray[dice - 2]++;
        }

        return counterArray;
    }


(Edit Also, the name of each method should (preferably) begin with a verb: counters \$\rightarrow\$ countResults and diceRoll \$\rightarrow\$ rollDice.)

Hope that helps.
