The set is an interface in Collection that supports only unique values. - Package set in the collection is java.util.Set; - Set extends collection but the class which implements set is different and the class name is HashSet. - We can define its datatype through generics as well such as greater then bracket Integer less then bracket #2 - Set also uses the add() method to insert the values in a set. - Set does not print the repeated values. It prints the same value only one time. - Set does not maintain the sequence, it gives values in any random order. The set does not sort the values - Set also does not support an index for values. #3 - Instead of using the class HashSet, if we will use the TreeSet, it will give values in sorted order. - All the elements in a TreeSet are sorted as it extends AbstractSet and implements NavigableSet and further NavigableSet extends Sorted Set. #4 - Collection interface extends an Iterable interface through which we can iterate between the elements by using enhanced for loop, etc. - Iterable interface contains a method called iterator(). - Iterator returns an iterator object that got all the values from a set. It can be in place of loops. - It has also a method called next() that gives the values of the next element. - It has a method hasNext() that helps the loop to know that the set contains a value of the next element. while(values.hasNext()) System.out.println(values.next()); Github repo : https://github.com/navinreddy20/Javacode.git More Learning : Java :- https://bit.ly/3x6rr0N Python :- https://bit.ly/3GRc7JX Django :- https://bit.ly/3MmoJK6 JavaScript :- https://bit.ly/3tiAlHo Node JS :- https://bit.ly/3GT4liq Rest Api :-https://bit.ly/3MjhZwt Servlet :- https://bit.ly/3Q7eA7k Spring Framework :- https://bit.ly/3xi7buh Design Patterns in Java :- https://bit.ly/3MocXiq Docker :- https://bit.ly/3xjWzLA Blockchain Tutorial :- https://bit.ly/3NSbOkc Corda Tutorial:- https://bit.ly/3thbUKa Hyperledger Fabric :- https://bit.ly/38RZCRB NoSQL Tutorial :- https://bit.ly/3aJpRuc Mysql Tutorial :- https://bit.ly/3thpr4L Data Structures using Java :- https://bit.ly/3MuJa7S Git Tutorial :- https://bit.ly/3NXyCPu Donation: PayPal Id : navinreddy20 https://www.telusko.com
