Given the code fragment:
public class Foo {
public static void main (String [ ] args) {
Map
unsortMap.put (10, "z");
unsortMap.put (5, "b");
unsortMap.put (1, "d");
unsortMap.put (7, "e");
unsortMap.put (50, "j");
Map
Comparator
@Override public int compare (Integer o1, Integer o2) {return o1.compareTo
(o2); } } );
treeMap.putAll (unsortMap);
for (Map.Entry
System.out.print (entry.getValue () + " ");
}
}
}
What is the result?
The code initializes a HashMap with various key-value pairs and then transfers the data to a TreeMap with a custom comparator that sorts the keys in natural ascending order. The for-each loop then iterates through the TreeMap, printing the values in the order of the sorted keys: 1, 5, 7, 10, and 50, which correspond to the values 'd', 'b', 'e', 'z', and 'j' respectively.
