Java Radomly Generating Numbers Error

I am writing this code to run 10000000 times and randomly generate a number and pick the most oftenly generated number, but the results do not seem random. The I have written is

public class Randomizer {
    public static int[][] numbers = new int[45][2];
    public static int maxN = 0;
    public static int finalChoice;
    public static void main(String[] args){
        int arithmoi[] = new int[5];
        for(int i =0; i < 5; i++){
            arithmoi[i] = randomizer(1000000, 45);
            System.out.println("A "+i+": "+arithmoi[i]);
        }
        int extra_num = randomizer(1000000, 20);
        System.out.println("\nT: "+extra_num);


    }

    public static int randomizer(int times, int amount){
        int[][] numbers = new int[amount][2];
        for(int i = 0; i < amount; i++){
            numbers[i][0] = i + 1;
            numbers[i][1] = 0;          
        }

        for(int i = 0; i < times; i ++){
            int rnd = (int)(Math.random() * amount + 1);
            for(int j = 0; j < amount; j++){
                if(rnd == numbers [j] [0]){
                    numbers[j][1] ++ ;
                    break;
                }
            }
        }
        for(int i = 0; i < amount; i++){
            if(maxN < numbers[i][1]){
                finalChoice = numbers[i][0];
                maxN = numbers[i][1];
            }           
        }
        return finalChoice;

    }



}

The result that it gives me are A 0: 36 A 1: 36 A 2: 36 A 3: 36 A 4: 29

T: 14, A 0: 26 A 1: 44 A 2: 44 A 3: 44 A 4: 44

T: 4 and similar. What could the problem be?
