One of the best tutorials for Java available online. Durga sir, your teaching quality is unparalleled. All other online java tutorials are nothing infront of your tutorials. For a beginner like me, you have made Java so simple that now I do not have any issues with it. Keep up the good work Sir. Wish you all the best.

Now after listening your lectures,I have no words to compare your teaching skill. But i strongly believe that god came into my life to teach me java and also to give hope on my life and career in the form of durga sir 🙏🏻

one more difference between HashMap and HashTable is that whenever we iterate entry from hashMap it will iterate in ascending and in HashTable it will come in descending order naturally (*if key will be integer number)

retrieve keys 28:30 ** retrieve only keys: Set keySet() ** retrieve only values: Collection values() Key + Values = Entry Set entrySet() Entry interface 31:50 without existing Map object, there is no chance of existing Entry object. So Entry is an inner interface of Map interface.

Map.Entry is nothing but interface but then how the object m1 was created in the above example???Since interface objects can't be created?

Thanks for such awesome explanation. When we print entrySet , it is printed in following manner: [K=V, K=V,...] Is there any toString() method in action here..?

Sir, hashmap's underlying data structure is hashtable. So, the hashmap shd also be synchronized. But it is not. Why?

Both HashMap and Hashtable are implemented using Hash Table dataStructure.

Hi Akash, it is not Collection Interface, this is Collections class which extends Object class, it has common methods of collection and Map interfaces related classes, and synchronizedMap() method is one of them.

sir for KeySet(),values(),entrySet(), how can we invoke them using Map object?Map is an interface know sir!
@vishalpanwar9550
@vishalpanwar9550 6 жыл бұрын
We are invoking these methods on implementation of Map interface i.e HashMap class and not on Map interface.
