Write a method named swapPairs that accepts an array of strings as a parameter and switches the order of values in a pairwise fashion. Your method should switch the order of the first two values, then switch the order of the next two, switch the order of the next two, and so on. For example, if the array initially stores these values:

I am trying to write a code that swaps 1st element of an array with 2nd one, 3rd with 4th and keeps like that. It is not working and instead I wrote a code that is reversing the order. (better explanation on pictures attached.) I am using Java. 

public static void swapPairs(String[]array) {
for(int i= 0; i< array.length / 2; i++) {
int j= array.length - i -1;
swap(array, i, j);
}
}
public static void swap(String[] array, int i, int j) {
String temp= array[i];
array[i]= array[j];
array[j]= temp;
}
