6.5. Returning Decimals¶
Let’s see what it looks like to return a decimal from a method. Take a look at our
Actor class again, but notice that there is a new method! It’s named
getNetWorth and it returns the total amount of money that an actor has earned.
As you can see, the value stored in the attribute
netWorth is being returned by the method
getNetWorth every time it is called. In other words, the call statements found within the
Main class are literally being replaced by the value stored in each object’s
neWorth attribute. This allows us to use the dot operator in new and useful ways because this allows us to embed function calls wherever we need to plug in a specific value related to the state of an object.
Can we do the same thing for booleans? Keep reading to find out!
