I don't understand What's the difference between a Priority Queue and an ordered array/linked list that are kept ordered when inserting/removing elements?
Bro, I have been watching videos/reading webpages for the better part of 1h and not one single dickhead could explain this as clearly as you did. THANK YOU!
Hey brother, I have a question that how to run code when a jlabel or jpanel touches another jlabel or jpanel in java? I think you will reply and help me...
Face reveal not necessary BUT, good news for you is he promotes his 2nd channel with a logo of himself holding a dog (that's 2 for 1, him and a dog). Go give a subscribe 👍
Yes, you can use Collections.Sort() for arrays in Java. Priority queues are different in implementation from an array. In theory, PQs can be implemented using arrays, but it's not recommended.
