what I'm trying to do is filling an array of 20 integers with random numbers, and then printing out the number of times each integer repeats itself. I'm getting an error when trying to print out the number of repetitions... Here's my code:

```
package nivel3;

import java.util.Random;

public class exercicio3 {

    public static void main(String[] args) {
        int[] numeros;
        int i=0;

        numeros=new int[20];

        Random rand=new Random();
        System.out.println("FILLING ARRAY WITH 20 RANDOM INTEGERS (FROM 0-9) \n");
        do {
            for (i=0; i<20; i++) {
                numeros[i]=rand.nextInt(10);
                System.out.printf("position"+i+of numeros[20]: "+numeros[i]+"\n\n");
            }
        } while (i<20);

        System.out.println("--------------------------------------------------------------------- \n");
        System.out.println("SHOWING THE REPEATED POSITIONS (FOR EACH POSITION OF THE ARRAY)\n");

            for(int j=0; j<20; j++) {
                int k=0;
                do {
                    k++;
                    if (numeros[j]==numeros[k]) 
                        System.out.printf("the integer in the ["+j+"] position is equal to the integer in the ["+k+"] position \n");

                }while (k<20);
           }
    }
}

```

Here's the error code:

```
