I know im asking randomly but does any of you know a way to get back into an Instagram account?? I somehow forgot the login password. I appreciate any tips you can give me
@Billy Dominic i really appreciate your reply. I found the site thru google and Im in the hacking process atm. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
I had struggled with figuring out what polymorphism is for weeks But with just watching this video I feel the power in my hands, everything is so clear now I extremely respect what you did
another way is to use instanceof inside the for loop, we each time check : if ( x instanceof Car ) x.go(); if ( x instanceof Bicycle ) x.go(); if ( x instanceof Boat ) x.go(); In case someone don't want to redefine the method go in superclass
my classmates and my batchmates kept on asking me how come i already know all the topics our professor taught.. i told them i binged watch youtube tutorial on your channel and ask them favor subscribe , like and comment . so you'll make more videos for us... we learned so much from you more than what is taught in our school we so much appreciate your efforts bro..🥰🥰🥰
Thank you for the Video, you explained it amazingly. I didn´t need to wind the video back, I just got it instantly (and i´m usually one of the slow learners)! I will definitely come back and learn more! :)
Loop Through an Array with For-Each There is also a "for-each" loop, which is used exclusively to loop through elements in arrays: for (type variable : arrayname) { ... } example:- String[] cars = {"Volvo", "BMW", "Ford", "Mazda"}; for (String i : cars) { System.out.println(i); } output:- Volvo BMW Ford Mazda
Thanks, nice video. In this case the parent class can be modified and x method was included. What if we need to extend somebody's else class? Implement an Interface?

if ( x instanceof Car ) x.go();
if ( x instanceof Bicycle ) x.go();
if ( x instanceof Boat ) x.go();
In case someone don't want to redefine the method go in superclass
we call it narrowing down in polymorphism
Wow, astonished on how well explained that was. Great video.

good mr bro
I appreciate your help in making this lesson easy.
Great video simple and clear
You are the best Bro. I really appreciate what you did. May the God bless you and keep you enjoy with a happy and relax life all the time.
As always: a brilliant and helpful tutorial vid! I really appreciate you content, it really helps me learn Java!
Keep up the good work bro!
great video bro! Also in your examples can you include user input, i think its an important skill to memorize
Thanks great job keep going
very good teachin and clear example. Thank you!
This is the best video to understand polymorphism. No doubt! Thank you a lot Bro ❤

Your explanations are perfect
Thanks for this videos, you are the best lecturer bro!
Great example
thank you so much, i watched many vids trying to learn this stuff, no one can teach it like you do
You are the best, thank you for helping me through college
I didn't know u could tell a for loop to go through all entries of an array. That's super useful
Loop Through an Array with For-Each
There is also a "for-each" loop, which is used exclusively to loop through elements in arrays:
for (type variable : arrayname) {
...
}
example:-
String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
for (String i : cars) {
System.out.println(i);
}
output:-
Volvo
BMW
Ford
Mazda
