I don't understand the connection between the drive methods

I figured out the solution to the problem but I don't understand how and why it works.

When you have

public void drive(int laps) {

mBarsCount -= laps; }

Then you make the non parameter drive

public void drive() {

drive (1); }

How would the non parameter function know to subtract mBarsCount for each single lap?

The non-parameter method is calling the drive method that takes 1 parameter within itself, providing it 1 as the lap argument, so when you call drive() the code within drive(int laps) will also get run with 1 as the lap argument due to the fact that it is called within the drive method.
