Question

I iterate through an ArrayList this way:

for (T t : list){
  ...
}

When I did this, I never thought I had to access the previous and next eleme

You can access any element in ArrayList by using the method get(index).

import java.util.ArrayList;


public class Test {
    public static void main(String[] args) {
        ArrayList array = new ArrayList();

        array.add(1);
        array.add(2);
        array.add(3);

        for(int i=1; i
