 is called, it is put on the right side 

of an assignment statement. On the left is a variable that will receive the value returned by 

AreaPerPerson( )

. Thus, after

areaPP = house.AreaPerPerson();

executes, the area-per-person of the 



house

 object is stored in 



areaPP

.

Notice that 



AreaPerPerson( ) 

now has a return type of 



int

. This means that it will return 

an integer value to the caller. The return type of a method is important because the type of 

data returned by a method must be compatible with the return type specified by the method. 

Thus, if you want a method to return data of type 

double

, then its return type must be type 



double

.
