Write a method with the header public static void swapAdjacent (int[] values) that takes a reference to an array of integers values and swaps adjacent pairs of elements: values[0] with values[1], values[2] with values[3], etc. For example, if you add the following test code to your main method: int[] a1 = {0, 2, 4, 6, 8, 10}; swapAdjacent (a1); System. out. println (Arrays. toString (a1));

public static void swapPairs (int[] a) {

int len=a. length;

if (len%2 = =0) {

for (int i=0; i
a[i]=a[i+1];

a[i+1]=a[i];

int[] b={a[i]+a[i+1]};

}

}

if (len%2!=0) {

for (int j=0; j
a[j]=a[j+1];

a[j+1]=a[j];

a[len-1]=a[len-1];

int[] b={a[j]+a[j+1]+a[len-1]};

}

}

}

public static void printArray (int[] a) {

System. out. println (a);

}
