Java 8 Modify Fields with reflections

Question

I have have a problem with this field:

private final String name = "test";

I want to modify it with reflections, but it doesn't work.

Field field = Test.class.getDeclaredField("name");
field.setAccessible(true);
field.set(OBJECT, "Paul");

But after this code,... the field is the same.

If I create the field with the following code:

private final String name;
    
public Test() {
   name = "test";
}

It will work..., but not with the first code :( Is there a way to do it with the example below? Any help?
