以下代码有什么区别..

int i=0;
List<CustomerReqRespEntity> customerReqRespEntities=new ArrayList<>();
for(int x=0;x<4;x++){
   CustomerReqRespEntity customerReqRespEntity=new CustomerReqRespEntity();
   customerReqRespEntity.setEntryId(++);
   customerReqRespEntities.add(customerReqRespEntity);
}

// ------------------------------------------------ ---------------------------

int i=0;
List<CustomerReqRespEntity> customerReqRespEntities=new ArrayList<>();
CustomerReqRespEntity customerReqRespEntity=new CustomerReqRespEntity();
customerReqRespEntity.setEntryId(i++);
customerReqRespEntities.add(customerReqRespEntity);

CustomerReqRespEntity customerReqRespEntity=new CustomerReqRespEntity();
customerReqRespEntity.setEntryId(i++);
customerReqRespEntities.add(customerReqRespEntity);

CustomerReqRespEntity customerReqRespEntity=new CustomerReqRespEntity();
customerReqRespEntity.setEntryId(i++);
customerReqRespEntities.add(customerReqRespEntity);

CustomerReqRespEntity customerReqRespEntity=new CustomerReqRespEntity();
customerReqRespEntity.setEntryId(i++);
customerReqRespEntities.add(customerReqRespEntity);
