//print elements at even index
for(i=0;i<numbers.length;i+=2)
System.out.print(numbers[i]+" ");
System.out.println();
//print even elements
for(i=0;i<numbers.length;i++)
{
if(numbers[i]%2==0)
System.out.print(numbers[i]+" ");

System.out.println();
//display elements in reverse order
for(i=numbers.length-1;i>=0;i--)
System.out.print(numbers[i]+" ");
System.out.println();
//display first and last element
