Java Copy Fields From One Object to Another Object with Reflection
28-11-2015Using Java Reflection, we can copy fields from one object to another object by using below class:
public class FieldCopyUtil { public static void setFields(Object from, Object to) { Field[] fields = from.getClass().getDeclaredFields(); for (Field field : fields) { try { Field fieldFrom = from.getClass().getDeclaredField(field.getName()); Object value = fieldFrom.get(from); to.getClass().getDeclaredField(field.getName()).set(to, value); } catch (IllegalAccessException e) { e.printStackTrace(); } catch (NoSuchFieldException e) { e.printStackTrace(); } } } }
We can call setFields() method like this:
BelgeGuncelle belgeGuncelle = new BelgeGuncelle(); BelgeKayit belgeKayit = getBelgeKayit(belge); FieldCopyUtil.setFields(belgeKayit, belgeGuncelle);
