TreeSet Details part 2

[@thelight_]

Awesome Lecture Sir, You still are in play. Best teaching style. Appreciated.

[@remeshkumar7612]

Small correction: StringBuffer implements Comparable starting from java 11.

[@puneethchidura3713]

thanks for the informarion. It really helped me.

[@AbhishekPandey-mi1wi]

This video was released on May 3, 2014, we have Java 1.8 at that time. Whatever he has taught, it is correct. However, you are commenting after 7 years with upgraded version changes, which wouldn't really make any sense.

[@sumantkumar5650]

Yes Sir, I am able to get the output for StringBuffer program. I am having latest java. Thank you so much sir for this type quality teaching.

[@IamJ____0001]

ya thanks mannn...

[@prakashreddy773]

2:25 Now in 2023 TreeSet implements comparable Interface sir. The Code is working fine.

[@SahilRajput-wg2ep]

finally , i thought why my code is working lmao, btw thanks mate.

[@SahilRajput-wg2ep]

now can we say that there are only 3 constructors in java ? as comparable is implemented by default ??

[@amandeepsingh2314]

really sir,you done a great job. best teacher available online

[@persistencej3116]

god bless you sir ... thanks a lot for these tutorials

[@shruthireddynallabolu7736]

Really good job Durga garu, i like your teaching style.

[@sheikh.sameer]

As a side note: that is a half truth that TreeSet doesn't allow null. It depends on the implementation of your comparator. If you want to add null anyhow, tune your comparator such that it allows nulls. eg. TreeSet ts = new TreeSet(new Comparator() { @Override public int compare(Object o1, Object o2) { return o1==null?-1:(o2==null?1:0); } }); ts.add(null); ts.add(null); System.out.println(ts); ------O/P------- [null, null] If you are using TreeSet with natural sorting, it doesn't allow null.

[@avatargirase]

For Interview Questions :- Try inserting t.add(new StringBuffer("MyString")) only once and run. Jvm wont throw any exception as there is nothing to compare with. Once you start adding another entry jvm need comparison thing.

[@wasiimo]

Interesting never thought of that one.

[@Anillkumargallipelli7219]

Yes bro, JVM never thrown any exception

[@techhub9269]

Thanks sir... you are really doing well

[@fardilviews]

But from my case, I don't find any exception import java.util.TreeSet; public class TreeSetDemo2 { public static void main(String[] args) { TreeSet t = new TreeSet();//should homogeneous and comparable t.add(new StringBuffer("A"));//StringBuffer are not comparable t.add(new StringBuffer("Z")); t.add(new StringBuffer("B")); t.add(new StringBuffer("L")); System.out.println(t); } }

[@niteshsince1982]

Thank you very much Durga sir. very helpful.

[@SahilRajput-wg2ep]

IN 2023 now can we say that there are only 3 constructors in java ? as comparable is implemented by default ??

[@abhilashkokkonda1713]

Good explanation

[@prashantpharate]

It was possible to add a null element as the first element of a TreeSet/TreeMap in Java 6, but it was considered a bug:

[@half_dreamy100]

Thank you Sir, these vedio help me a lot

[@IamJ____0001]

[@Rohtube]

Collection.sort(MyList); in MyList list, there are object of class Student. Class student have two fields, Name and ID If we dont specify the comparator, what will be the sorting order for that list ? will it be sorted on name or ID ??

[@valajagdish1049]

i salute you.

[@ankitsharma2k2009]

please upload map concepts sir. Thank you

[@jvsnyc]

They give you so much free stuff it is really hard to find it all, isn't it? kzbin.info/www/bejne/poSqp5WAbKx9bJo

[@vamshikrishna298]

sir where is the maps concepts

[@ranjithrao3835]

good

[@avinashkumargond3291]

Sir, I am using java 11 and I can see StringBuffer and StringBuilder implements Comparable, so now adding of stringBuffer object will work naa?
