Analyse the following code :

 public class Test { public static void main(String[] args) { int[] a = {1, 2}; swap(a[0], a[1]); System.out.println("a[0] = " + a[0] + " a[1] = " + a[1]); } public static void swap(int n1, int n2) { int temp = n1; n1 = n2; n2 = temp; } } 

Which of the following shows correct printout?Question options:

	a[0] = 2 a[1] = 1
	a[0] = 0 a[1] = 0
	a[0] = 1 a[1] = 2
	a[0] = 2 a[1] = 2
	a[0] = 1 a[1] = 1
