Instead of just using the return keyword, wouldn’t it just be possible to simply type in System.out.println(tires) and then call that method in main? By the way this is related to the example that they put in the instructions.

As you progress through learning Java and other languages should you choose to do so, you’ll find that returning values is extremely useful. You could just print the number of tires to the console, but if you wanted to do something else with that value it would be lost if the method didn’t return it to the line of code where the method was called. When returned, we could use the value in an equation, assign it to a variable for later use, send it as an argument to be used as a parameter in another method, etc.

Basically I get the systematic of the taskflow among the main() method and the other methods. But why does not need the “getPriceWithTax” method parameters?
