Initializing Arrays

Take the code below and add methods to initialize the array to make what is in the comments. The first one is done for you.

//initializing arrays
public class initialize
{
   public static void main (String args [])
   {
   int size = 30;
   int a [] = new int [size];
   
   //0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 
   allZeros (a, size);
   printarray (a, size);
   
   //1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 
   allOnes (a, size);
   printarray (a, size);
   
   //0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1
   zeroOnes (a, size);

   zeroOneTwo (a, size);
   printarray (a, size);
   
   //0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

   printarray (a, size);

   fibonacci(a,size);
   printarray(a,size);
   }

    public static void printarray (int a [], int size)
    {

        {
            System.out.print (a [i] + " ");
        }
        System.out.println ();
    }

    {

        {
            a [i] = 0;
        }
    }
