How to iterate elements of an integer arraylist in Java

I understand that when you iterate a regular array element it is like so:

int[] counter = new int[10];

for loop{
counter[i] = 0;
}

when button clicked{
counter[0]++; //For example
counter[6]++;
}


However I'm not understanding how to iterate through elements of an arraylist. If someone could help me understand I'll be appreciative. Thanks!

Answer

The easiest way would be to use a for each loop

for(int elem : yourArrayList){
   elem;//do whatever with the element
}
