@ChoovioHopi
Wow, it's really nice. It's very attractive
@khushansharora3383
33:59 advanced questions
@willburghard966
good video… but the beginner questions are harder than the intermediate questions.
@petersouthwell5971
Why did you overlook discussing modules when talking about packages?
@dvp7388
Thanks for a very informative video
@bloom6874
too good ☺💖
@sachinjarral4348
Worst video ever. Missed all important interview questions and no explanation
@prakashp1970
Answer of 28 question is yes, we can overload static method
@rahulwasatkar4363
q 28 : you says like static method can not overload .. but we can overload the static method . but we cannot overload two methods in Java if they differ only by static keyword (number of parameters and types of parameters is the same).
@BABABENNETT
Awesome
@aniruddhadhandar
JDBC is an abbreviation for "Java Database Connectivity", not a connector.
@Chosenn1
Get more assistance in comments section than Video..!!
Thanks !
@sremonkarmakar2715
java automatically allocate memory.
@stevanhartig5573
I do not know who did this video, but it has so much wrong informations.
@garkman5000
This video has many inaccuracies. I do not recommend anyone watch it to prepare for interviews.
Some problems I saw before I stopped watching
1) Singelton classes were not properly explained at all. This is a bigger subject than I can cover here.
2) Access modifiers were very poorly explained. The most important one on there from the standpoint of an interviewer trying to see if you really know your material (IMO) is the protected modifier. Only a hand waving explanation was given in the video. In essence inheriting classes from OTHER packages can access (unlike package private)
3) Method overloading was flat wrong. The return signature DOES NOT MATTER. Try it yourself, declare two functions with the same method parameters and different return types.
4) Static method overloading, this was really poorly described and I think the speaker was confused himself. You cannot overload a static method with an instance method with the same method signature (ie write the same method, except put a static keyword in one). You can however have two static methods with different method signatures (ie parameters).
I stopped watching after overloading. You are better off passing on this video, rather than learning incorrect information.
@gbird373
Toooo many wrong answers!!
@Suirady
This video is full of errors, will create more confusion to begginers instead of actually helping out! Choose your information carefully
@TZGamer-td46
Q.28. We can overload static method . As overloading happens at compile time and static method binds at compile time So we can overload static method.
public class StaticMethodOverloading {
static void display(int a){
System.out
.println("Value of a : "+a);
}
static void display(int a,int b){
System.out.println("Value of a: "+a+" And value of b: "+b);
}
static public void main(String[] args){
display(5);
display(7,9);
}
}
Above example will be complied without any error
@sreelakshmips2581
Thank you so much
@vinodmahato2505
lot of wrong answers 🙄
@renugas3162
Can you share the ppt
@anilabaladas1535
i wish you could give example and explain
@sreejithvignesh192
Q27: Method overloading cannot be done with return type modification. Please check and update in the video
@sreekanthvadassery8288
A static method can be overloaded, but can not be overridden in Java. Correct your answer please.
@nikhilparakh5297
Your choice of questions are very accurate but you missed few oops concepts, this video is really helpful. And I am glad I found your video.
Thanks and thumbs up from myside.
