Why did u called accountbalance variable using object even though we declared that variable using static? We could have called that without using object right?
Hi Bro, If we need not to create object to call a static method, then what is the significance of methods which doesn't static.? Can we always create static methods?
Then there is no point in using object oriented programming. But this is an interesting question though. This should be asked and answered by the developer himself. Should this method really be called, even of there are no objects created? If yes make it a else, non static. Static methods consumes a significant amount of memory. Polymorphism goes out if the methods are static. As static methods can't be overridden. Like these there are multiple reasons.
Both are not comparable. Block is just a section in which the code is written. For methods also there are blocks. {} Anything which reside I aide these curly braces are blocks. Blocks are associated with methods, classes, even plain static blocks are also available. Method is one which we write to accomplish a specific task
Bro I declare two variables one is static variable and another one is normal variable but two variables are same name how it's possible explain pannu ga bro please.
Static variable declare inside the class, Normal variable declare inside method both are same name and declare inside the same class how it's possible bro please. 🤔
Bro when I practice, while doing the static block example, even though I created object for the static block, I can get the correct output in console. I give two static blocks and created object for them separately and I call the static block by the object. It gives the output.
As bro said in video, it throws a warning when you are calling a static method from static main method...so compiler will run... But you can't call a non static method from main method without creating object
really you are great bro crystal clear explanation even in coaching centers they wont say it that clear awesome!!
Your teaching way like a r&d way of teaching ❤❤❤
proud to be ur student
Great content. i thought i was clear about static. but this shed more light on the concept.
u are good teacher
Quick Summary on Calling method - Whether we need obj creation or not:
Static method calling inside Static method -> Method Can be accessed directly, No Obj creation needed.
Static method calling inside Non-Static method -> Method Can be accessed directly, No Obj creation needed.
Non-Static method calling inside Static method -> Method Cant be accessed Directly, Obj creation needed.
Non-Static method calling inside Non-Static method-> Method Cant be accessed Directly, Obj creation needed.
(note: Correct me if I am wrong, Guys !)
Deep and clear explanation
Hi we can call a static method from the non-static method, but not other way around (you mentioned as otherwise) please change 0.29
Bro, Can u plz tell me y we use static keyword in main method? In all interviews they are asking and please tell me y we wnt to use main method?
Hai bro how can i get only core java text files for studding.
Awesome Man
Hi Arul,
Is static variable always be initialized as shown in the example:
static int accountBalance = 0;
Having same doubt
If you were cleared means let me know sis

Hi Sir,
Could you please upload the video about Scanner in this java crash course playlist.
Java Crash course is for core Hava concepts and programming fundamentals. In java programs Playlist, scanner concepts are there

good explanation
Anna we can't use static keyword to class..because it will not allow as to create object

Static variable declare inside the class,
Normal variable declare inside method both are same name and declare inside the same class how it's possible bro please. 🤔
class ss{
static int i=1;
void add(){
int i=2;
}
}
OUTPUT: 2
One is class level and another is local inside a method. That's allowed
