Write the output that is printed when the given method below is passed each of the following maps and lists as its parameters.
Recall that maps print in a {key1=value1, key2=value2, ..., keyN=valueN} format.
Though hash maps usually have unpredictable ordering, for this problem, you should assume that when looping over the map or printing a map, it visits the keys in the order that they were added to the map or the order they are declared below.
If a map calls put() on a key that already exists, it retains its current position in the ordering.
public static void collectionMystery5(ArrayList<String> list1, ArrayList<String> list2) {
HashMap<String, String> result = new HashMap<String, String>();
for (int i = 0; i < list1.size(); i++) {
String s1 = list1.get(i);
String s2 = list2.get(i);
if (!result.containsKey(s1)) {
result.put(s1, s2);
} else if (!result.containsKey(s2)) {
result.put(s2, s1);
} else {
result.put(s1 + s2, s1);
}
}
System.out.println(result);
}
