How to set java object attribute like the way in javascript

Question

All:

I have a data model object in Java like:

class Model {
    String name;
    String email;
}

What I want to do is dynamically determine what attribute I want to set by using a variable like in Javascript object;

String field = "name";

// This is what I try to achieve, not the real code.
New Model().field = "according content";
or 
New Model()[field] = "according content";

Thanks

You could reflection as in this link

In this example they have

   public long chapters = 0;

and can get/set it as

    Field chap = c.getDeclaredField("chapters");
    out.format(fmt, "before", "chapters", book.chapters);
    chap.setLong(book, 12);
    out.format(fmt, "after", "chapters", chap.getLong(book));
