My 6 months of coding knowledge and understanding in 1 hr 15 minutes. To those people who had trouble understanding hashcode, equals, comparator, comparable: just keep trying, you will understand it. Comparator is really important because sometimes to solve a Q, you need to sort the input data in a particular way, which can be easily done with the help of comparator.

@karanpatel8996 3 года назад

This was great! My suggestion for next video would be for advanced collection concepts. A few examples 1) Advanced functions like map.compute() 2) How collections are internally implemented 3) Thread safe collections like concurrent map and synchronized set and their internal workings.

@diptanshuagrawal5040 2 года назад

Also a note to everyone, please watch this before you start leetcoding. Jaise khaana banane se pehle kaunse bartan use karne hain pata hona chhaie, waise hi coding ke liye java collections framework ka accha idea ho toh coding main maza aata hai. It helps to figure out what to use and how efficiently.

Watched this video today, and I must say that I was here after learning about Collection frameworks. Still, I found this video useful because of the things you mentioned about time complexity and having unique custom objects for Set collections. Also, you made Comparator, and Comparable look so easy. Thanks for this tutorial, I'm having an interview within a few days and I hope I can crack it.

@namrata.nagdev 3 года назад

Just to update : There has been a change internal working of arrayList (Till java 6) newCapacity = (oldCapacity * 3/2)+1 = 16 (java 7 or later) newCapacity = oldCapacity + (oldCapacity >> 1) = 15 Default Capacity * Load Factor = Threshold (10* 0.75 = 7) The number of buckets will automatically get increased when the table has 7 elements in it. ArrayList which is 50% more than the old capacity

what's the difference between PriorityQueue = new PriorityQueue(); vs Queue = new PriorityQueue(); what are the pros and cons of each i can see from diagram PriorityQueue is a class that implements the Queue interface so both syntax should be fine i guess but which one should i use
