reflection: java reflection. Can not set java.lang.Long field model.vo.Student.name to java.lang.Class

dimanche 21 décembre 2014

why the following code:


        Field idField = t.getDeclaredField("id");
        idField.setAccessible(true);

        Long o=  (Long)idField.get(t);

has the problem Caused by: java.lang.IllegalArgumentException: Can not set java.lang.Long field model.vo.Student.name to java.lang.Class

and the id is the Long type
