Java Exchange Position Elements

Write a java program to exchange the every odd position element with the corresponding even position element. the array may have the odd numbers of elements or even numbers of elements.

Input: 15 7 18 21 9 12 87 25 8 5
output: 7 15 21 18 12 9 25 87 5 87

Apply swap logic for every odd position element and even position element of an array. but no need to think about the total no of elements of the array. It may be even numbers of elements or odd numbers of elements

	class OddEvenExchange
	{
		public static void main()
		{
			int []arr={15,7,18,21,9,12,87,25,8,5};
			int i,temp;
			System.out.println("\nAfter Exchange");
			for(i=0;i<arr.length;i++)
			{
				System.out.print(arr[i] + " ");
			}
			for(i=0;i<arr.length;i+=2)
			{
				temp=arr[i];
				arr[i]=arr[i+1];
				arr[i+1]=temp;
			}
			System.out.println("\nBefore Exchange");
			for(i=0;i<arr.length;i++)
			{
				System.out.print(arr[i] + " ");
			}
		}
	}
