So I completed the entire video of Collection today and I must say "Durga Sir " is one of the best teachers I have ever seen. The best teacher to give left and right to java language ..
@@kishankumar8074 What is current tech stack good for Software development if not Java? Is Java still worth to learn? You inputs will be helpful. Thanks
@@ManojKumar-nf4wr Yes it is still worth to learn Java , since if you understand these basic concepts well , you can learn any Programming Language easily.
I just want to thanks you from my bottom of my heart.. you are doing such a great job .. No one in this world is so generous to provide such a knowledge for free. You are a true Guru.. Thanks sir. Big fan of yours..

Sir i have a doubt you create a student array with object s and you write student and customer you says that customer is not valid that will shows an error then at the time of video 9:34 you create a Object array with object name "a" what is difference between above student array and object array how it takes similar types
Thanks Sir.Video is wonderful .One correction here .In java ,array is regarded as an Object.So we know that collection can store any Object type. So int[] and Integer[],both can be added to Collection.

Hello @ Durga Sir!

Collections are not recommended where performance is required. That is because of the growable algorithm. So what if we are using collection like Array. From which I mean what if we already know the size the collection then will there be any performance issue? If I'm restricting the code from adding any new element after the limit. Then can I use collection or are there any other performance related issues? Say I want to use a method that is provided in collections and not in arrays. Please help me understand this.
Nobody ever answered you it seems. 1. The problem with Collections is not because they are growable. For some very high performance things, you might be sad that your ArrayList can only hold wrapper classes. That is, you can't have an ArrayList or an ArrayList, only an ArrayList or ArrayList This will go away whenever Project Valhalla completes. You can use an Array and get all the access to all of the wonderful List methods by using the method in Arrays: asList() Integer[] iar = {2, 4, 6, 8, 10, 20, 40, 80, 160 }; List li = Arrays.asList( iar ); If you do this, your array will now be usable as a "fixed size list" that you can't add any elements to or remove any elements from, but you can read or change any of the elements either thru referencing elements of the array, or thru the List methods. Too bad, you still can't have a List at this time yet in Java. If that is super-important to you, you can use C#/.Net, where they have value types already for some years, or bite the bullet and learn C++, which is way, way more hard work than either Java or C#. However, the whole notion that you need more performance may be misguided, unless you are doing Google or Amazon-sized things it may not even make a difference. I hope that helped you a bit. Everyone loves Durga Sir, but some of the things he says here should be taken as somewhat generalized ideas. If you don't have a huge requirement for primitive types, ArrayList is not going to give you big performance problems compared to an Array of the same type.
So I completed the entire video of Collection today and I must say "Durga Sir " is one of the best teachers I have ever seen.

Are you still in java ?

thanks for sharing this tutorials on collection Framework.please update video tutorials on reflection Api by durga Sir
Great videos and thanks a lot for uploading videos , we are all thankful to you
Best explanation of all the topics
Sir i have a doubt you create a student array with object s and you write student and customer you says that customer is not valid that will shows an error then at the time of video 9:34 you create a Object array with object name "a" what is difference between above student array and object array how it takes similar types
awesome video for begineers
👌👏🥳🐎
thank you sir for uploading videos.
Thanks Sir.Video is wonderful .One correction here .In java ,array is regarded as an Object.So we know that collection can store any Object type. So int[] and Integer[],both can be added to Collection.
super sir

Collections are not recommended where performance is required. That is because of the growable algorithm. So what if we are using collection like Array. From which I mean what if we already know the size the collection then will there be any performance issue? If I'm restricting the code from adding any new element after the limit. Then can I use collection or are there any other performance related issues? Say I want to use a method that is provided in collections and not in arrays. Please help me understand this.
Nobody ever answered you it seems. 1. The problem with Collections is not because they are growable. For some very high performance things, you might be sad that your ArrayList can only hold wrapper classes. That is, you can't have an ArrayList or an ArrayList, only an ArrayList or ArrayList This will go away whenever Project Valhalla completes. You can use an Array and get all the access to all of the wonderful List methods by using the method in Arrays: asList()
Integer[] iar = {2, 4, 6, 8, 10, 20, 40, 80, 160 };
List li = Arrays.asList( iar );
If you do this, your array will now be usable as a "fixed size list" that you can't add any elements to or remove any elements from, but you can read or change any of the elements either thru referencing elements of the array, or thru the List methods.
Too bad, you still can't have a List at this time yet in Java. If that is super-important to you, you can use C#/.Net, where they have value types already for some years, or bite the bullet and learn C++, which is way, way more hard work than either Java or C#. However, the whole notion that you need more performance may be misguided, unless you are doing Google or Amazon-sized things it may not even make a difference.
I hope that helped you a bit.
Everyone loves Durga Sir, but some of the things he says here should be taken as somewhat generalized ideas. If you don't have a huge requirement for primitive types, ArrayList is not going to give you big performance problems compared to an Array of the same type.
its really good tutorial but do you have tutorials on java lambada , stream API??
looking forward to hear your response..
sir please upload video on adv java jdbc also you are the expert teacher i must say
