Hey everyone!

so i have a question about java. its about when you need to do the same thing to multiple variables with similar names. how would i reach each variable in a loop format?

thanks!!

Hmmm, not sure how to do that.
Have you considered using an Array or ArrayList? Those are very easy to iterate through.

You can't really. I definitely suggest an array instead.

Ya, you can make an array of nearly every data type. You can even have an array of arrays! :O

To iterate through all the elements, use an Enhanced For Loop, like this:
for (int myValue : myArray) { //runs loop for each value in myArray
System.out.println(myValue);
}

This simplifies code and eliminates using pesky counters and the mistakes associated with them.

You can also use an Iterator… though no one uses those anymore.
