Iterator has .next() - is there a way to get the previous element instead of the next one?

Question

I have an Iterator that I use on a HashMap, and I save and load the iterator. is there a way to get the previous key in the HashMap with Iterator? (java.util.Iterator)

Answer 1

Make your own Iterator:

public class EnhancedIterator implements Iterator{
    private List list;
    private int indexSelected=-1;
    public EnhancedIterator(List list){
        this.list=list;
    }

    @Override
    public boolean hasNext() {
        return indexSelected
