In this lecture we will learn:
– Set interface in the collection
– Syntax of set interface
– HashSet and TreeSet in a set collection
– Iterable interface in Collection
– How to use an iterator for iterating values

#1
The collection interface is also extended by the set interface.
– List in the collection supports repeated values. 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());
