How to name a method that sets some values in a javabean? Often I find myself setting various fields in a Javabean and then passing that Javabean to some method.

customerEntity.setName("Foo");
customerEntity.setAge(45);
customerEntity.setAddress(address);

em.merge(customerEntity);


Or 

requestPayload.setCustomerId(2343);
requestPayload.setCustomerPreference("green");
//lots more
sendRequest(requestPayload)


Not liking so much of data-population cluttering, I'd move those to a separate method.. 

public void doSomeOperation(Customer customer)
    {
          em.merge(prepareCustomerEntity(customer));
    }

private Customer prepareCustomerEntity(Customer customer)
   { customer.setName("Foo");
    customer.setAge(45);
    customer.setAddress(address);
    return customer;
   }


What would be a good name for such a method ? Maybe something like prepareXXX() or populateXXX()? Naming it as prepareXXX() makes it sound like a void method.. populateXXX() sounds better? Or should I just name it as setCustomerValues(). But setXXX() name makes it sound like a typical Javabean setter, which this is not.
I agree you should not use setXXX() as this sounds like a classic setter. I would say go with what you think sounds nice and conveys the meaning well. prepareXXX() sound nice to me. If it is default values you are setting, you could use something along populateWithDefaultValues().

Just make sure you use the same naming strategy throughout your application.
