[@erickpeculiar823]

Bro you are a goat ! tysm

[@jadilsalman548]

All the way from middle east.. Thanks youre the best

[@sneakycheeky531]

cheers pal

[@martinmiciciday5235]

Yeah; thank you, it's very handy; and Also this is for nested loop: String[][] formlist = {{"Liam", "Olivia", "Emma" ,"Oliver" ,"Elijah"},{"Age", "Address", "lastName", "Password"}}; for(String names: formlist[0]) { for(String columns: formlist[1]) System.out.println(names + " , " + columns); }

[@JossinJax]

I apologize if you've already answered this, but why when you create a for each loop for your Arraylist of data type do you then use the primitive "int" to iterate through the Arraylist?

[@DrDoomCake735]

Is this for each loop only good for printing the entire array? Or can you limit it like the other for loops involving i=0; I< length; etc

[@MaximumJoy]

Wonderful

[@passatpower3600]

How can you make the loop go multippel times or as many times you want?

[@quentinli5802]

i watched your video about TicTacToe at yesterday ,and wanna to know about the for loop ,thank you about make this video.

[@latedeveloper7836]

I get most of it but is the 'String car' a completely new variable inside the for each loop? I see 'cars' in the String array declaration but no mention of a 'car' class or variable mentioned elsewhere. Any help much appreciated. Thanks

[@vornamenachname2858]

String car is just a new variable that contains all the contents from the array, but instead of having to make an entire for loop etc you can just print it out in a foreach loop. At least that's how I understood it

[@patrickhastings3733]

dude your videos are great! codecademy is alright, but seeing the code being written while intuitively explained is making it stick much more efficiently

[@thepowerx2965]

Good video! I 've a question: is it possible to put strings instead of integers in a if statement? in my code I put: if (name = "Jhon") {//do stuff} But I get error. Help pls PD: if there's a mistake is because I'm spanish so my english is sooo bad

[@alexlorenlee]

Great question! Change it to name == "John" :)

[@thepowerx2965]

@@alexlorenlee thanks! you're a very good teacher!

[@lloydderss1961]

how can I convert that String car to a String array again?

[@ARUNKUMAR-vi6uk]

Can we use "FOR EACH" to all alternatives of FOR LOOPS?

[@steved.1754]

Is foreach same as "enhanced" for loop?

[@joshblank4579]

for the last example with the array, what is "a" and why did you put "int a" in the for each loop?

[@jukka4519]

You have a variable called "a" where the type of data that stores will be int (integers), when you run the foreach, every number is going to be stored in that variable. It's the same as the cars example but with numbers

[@lilv728]

I think my professor said for each loops are mostly used for arrays. Is that right?
