Sorting a LinkedHashSet

Question

I\'m wondering if it\'s possible to sort a LinkedHashSet. I\'ve tried the statement

Collections.sort((List paragraph);

Howeve

Answer 1

Yes, You can. Java 8 has made our life easier :)

creating a linked list (it looks simple to me, you can directly insert in LinkedHashSet)

LinkedList lList = new LinkedList();
lList.add("Ravi");
lList.add("Vijay");
lList.add("Ravi");
lList.add("Ajay");
lList.add(null);

LinkedHashSet lHashSet = new LinkedHashSet<>();
lHashSet.addAll(lList);

let's sort now

lHashSet.stream().sorted((String s1,String s2)->{       
    return s1.compareTo(s2);
});

//now print it
System.out.println("----");
lHashSet.forEach(action->{
   System.out.println(action);
});
System.out.println("----");

Output-

----
Ravi
Vijay
Ajay
null
----

Happy Coding :)
