Java - map a list of objects to a list with values of their property attributes

Question

I have the ViewValue class defined as follows:

class ViewValue {

private Long id;
private Integer value;
private String description;
private View view;
priv         


        

Answer 1

That depends on what you then do with the List, and the List

For example you might get sufficient functionality from creating your own List implementation that wraps a List, implementing iterator() with an iterator implementation that iterates over the ViewValues, returning the id.
