import java.util.ArrayList;
import java.util.List;

public static void main(String[] args) {
    List<String> list = new ArrayList<String>();
    list.add("a");
    list.add("b");
    list.add("c");
    for (int i=list.size()-1;i>=0;i--) {
        String s = list.get(i);
        System.out.print("index:"+i+" value:"+s);
        if (s.equals("b")) {
            list.remove(i);
            System.out.print(" [ remove "+s+" from index "+i+" ]");
        }
        System.out.println(" list size:"+list.size());
    }
    for (String s : list) {
        System.out.print(s+" ");
    }
