Simple Array Printing

Take the following code and add the three methods needed:

• one method to print the array in reverse
• another methods to print every second element of the array starting with 0
• a final method to print every second element of the array starting with 1

public class moreBasicArrays
   {
   public static void main (String args [])
   {
   int size = 20;
   int a [] = new int [size];
   //0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 
   counting (a, size);
   printarray (a, size);
   
   //19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 
   printReverse (a, size);
   
   //0 2 4 6 8 10 12 14 16 18
   printSecond (a, size);
   
   //1 3 5 7 9 11 13 15 17 19
   printSecond1 (a, size);
   }

   public static void counting (int a [], int size)
   {
       for (int i = 0 ; i < size ; i++)
       {
         a [i] = i;
       }

   }

   public static void printarray (int a [], int size)
   {
     for (int i = 0 ; i < size ; i++)
     {
        System.out.print (a [i] + " ");
     }
     System.out.println ();
   }

}
