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
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?
It’s a for-each loop. It’s a variant of the for loop (kind of like the do loop is a variant of the while loop.) This same youtube goes over the concept in one of the videos in his 100 Java playlist. It’s probably the best (yet most underrated) explanation out there. Here’s a link: ua-cam.com/video/_IT8F5W0ZO4/v-deo.html

@Billy Dominic it worked and I now got access to my account again. Im so happy:D
Thanks so much you saved my account :D

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
great video bro! Also in your examples can you include user input, i think its an important skill to memorize
great video!!! I'm infinitely grateful for your dedication and big heart to share this knowledge with the world. Thank you soo much
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!
This is the best video to understand polymorphism. No doubt! Thank you a lot Bro ❤
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.
good mr bro
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

totally amazing tutorial, you got my subscribe after the second video. Thank you so much sir!
thanks man. keep up
You are a god of gods
This is kinda similar to array of objects like within a single object we are storing the other objects as well.
your vids are great
Good job, man!
Good

Just a comment down below
You should teach college classes!
I just don't understand how you can call other classes from the Main. You're not even including the package. Please help me understand this magic!
Just use "IntelliJ" (simpler) or "Android Studio" (more complex) and things become clear.
Does any one knows how to save the polymorphism code in java?
What do you mean by "save the polymorphism code" ?
I didn't understand that for loop😭
