Formatting multiple arguments passed to a function in Java

Question

Often the number of arguments passed to a function can be large. Consider the following case:

calculate(dataManager.getLastUpdate().getNumberOfChildren(),
               


        

Answer 1

I might assign the return values of the getNumberOf*() methods to variables:

SomeObject lastUpdate = dataManager.getLastUpdate();
int children = lastUpdate.getNumberOfChildren();
int parents = lastUpdate.getNumberOfParents();
int grandChildren = lastUpdate.getNumberOfGrandChildren();
calculate(children, parents, grandChildren, milliseconds, somethingelse);
