Copy all values from fields in one class to another through reflection

I have a class which is basically a copy of another class. ``` public class A { int a; String b; } public class CopyA { int a; String b; } ``` What I am doing is putting values from class `A` into `CopyA` before sending `CopyA` through a webservice call. Now I would like to create a reflection-method that basically copies all fields that are identical (by name and type) from class `A` to class `CopyA`. How can I do this? This is what I have so far, but it doesn't quite work. I think the problem here is that I am trying to set a field on the field I am looping through. ``` private <T extends Object, Y extends Object> void copyFields(T from, Y too) { Class<? extends Object> fromClass = from.getClass(); Field[] fromFields = fromClass.getDeclaredFields(); Class<? extends Object> tooClass = too.getClass(); Field[] tooFields = tooClass.getDeclaredFields(); if (fromFields != null && tooFields != null) { for (Field tooF : tooFields) { logger.debug("toofield name #0 and type #1", tooF.getName(), tooF.getType().toString()); try { // Check if that fields exists in the other method Field fromF = fromClass.getDeclaredField(tooF.getName()); if (fromF.getType().equals(tooF.getType())) { tooF.set(tooF, fromF); } } catch (SecurityException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (NoSuchFieldException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IllegalAccessException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } ``` I am sure there must be someone that has already done this somehow
