Where exactly is the default "1" being passed onto?

in the code

public void drive(int lapsleft) { lapsDriven+=lapsLeft; barCount-=lapsLeft; } public void drive() {drive(1);}

What parameter is the 1 taking by default? lapsLeft? lapsDriven?

The line drive(1) is just calling the drive(int lapsleft) with 1 as an argument. Which means that it ends up being passed to the lapsleft parameter.

Arguments (values passed into a function) is automcaitcally assigned to parameters based on position. So the first argument goes to the first parameter. Since 1 is the first argument and lapsleft is the first parameter 1 gets assigned to lapsleft.
