Traversing Hashmap In Java. What is the difference between clear and remove method of HashMap. HashMap in Java is like the legacy Hashtable class but it is not synchronized. Then using the next method we print the entries of HashMap.
We can use the Iterator interface to traverse over any structure of the Collection Framework. The reversal is done to avoid Tail Traversing and adding an element to the head. It allows us to store the null elements as well but there should be only one null key.
This allows the execution time of basic operations such as get and put to remain constant even for large sets. To sort the HashMap by values we need to create a Comparator. You want to first check if it is not null and return it only then.
