Please advise which method is preferred and explain why?

p is an Object of some kind.

A

if (new LaunchCompareJob(p).go()) {}

B

if (new LaunchCompareJob().go(p)) {}

A

if (new LaunchCompareJob(p).go()) {}

B

if (new LaunchCompareJob().go(p)) {}

imho: i would prefer the second because the object LaunchCompareJob don't need an explicit constructor to handle the argument p.

B

What happens here? Is this even possible? If so, yuck!

C

if (new LaunchCompareJob(p).go(p)) {}

D

if (new LaunchCompareJob().go()) {}

kind regards,

if the only thing LaunchCompareJob ever does is perform one operation on p, (A) is preferable. The user of the API won't end up in the situation when he (mistakenly) created a LaunchCompareJob and only then realized it cannot be used for Object p.

for (B), LaunchCompareJob must be stateless.
(B) will allow re-using of LaunchCompareJob for multiple executions with different arguments. If that's a possibility, (B) is better, cause you then create fewer objects.
