    Another way to update an existing object with all its fields in your Realm DB is using the method realm.copyToRealmOrUpdate():

    Object obj = new Object();
    obj.setField1(field1);
    obj.setField2(field2);
    realm.beginTransaction();
    realm.copyToRealmOrUpdate(obj);
    realm.commitTransaction();
    

    If your object has a Primary Key, this method will update the object automatically without duplicate objects 🙂

    More info: copyToRealmOrUpdate()

    You can user insertOrUpdate method to do this.Hope this helps

      Realm.getDefaultInstance().executeTransaction(new Realm.Transaction() {
                    @Override
                    public void execute(Realm realm) {
    
                        objectToEdit.setNewValue("string");
                        realm.insertOrUpdate();
                    }
                });
