In TreeMap implementation the code is wrong

for (Map.Entry<String, Integer> entry : myMap2.entrySet()) {
           System.out.println(entry.getKey() + ": " + entry.getEntry.getValue());
   }

a this shows error it should be replaced with

for (Map.Entry<String, Integer> entry : myMap2.entrySet()) {
            System.out.println(entry.getKey() + ": " + entry.getValue());
 }

then it will work.
