Example 1: Reverse an array in java using for loop

{
public static void main(String[] args)
{
int[] arrNumbers = new int[]{2, 4, 6, 8, 10};
System.out.println("Given array: ");
for(int a = 0; a < arrNumbers.length; a++)
{
System.out.print(arrNumbers[a] + " ");
}
System.out.println("Reverse array: ");
for(int a = arrNumbers.length - 1; a >= 0; a--)
{
System.out.print(arrNumbers[a] + " ");
}
