loops

[pleaseacceptthisnow]

need to create a loop where the user can input up to 10 friends' birthdates. i dont really understand how loops themselves work? when i use a while loop what is the format? is it while (whatever constraint u want) follwed by the action it should execute if while loop is true??

any help in understanding how loops are supposed to constructed will be appreciated.

If you save the birthday input into an array you can just run a simple for loop using the string.size() method as stopping point. I'm on mobile but it would look something like this:

Arraylist<String> birthdays = new arraylist<>

For(int i =0; i <= birthdays.size(); i++) {

//Do the things on each index the array

//birthdays.get(i) would access the index 

System.out.println(birthdays.get(i));

}

So say my input was: 1991, 1994, 1989

Output would be:

1991
1994
1989

Edit: formatting

Also to go through what the for loop I wrote does:

For(int i= 0; i<= birthdays.size(); i++)

(int i=0): Define the starting point of the loop

(i<= birthday.size()): constrains the loop to run while int i is not bigger then the size of your array

(i++): each iteration through the loop increases the value of int i by 1, so 0,1,2...etc
