1,905 PointsCreate a new method named drive that accepts no arguments. It should call the newer drive method passing in a 1 for the
I could not understand why we are passing 1 by calling old one in the new drive method with no argument ?
class GoKart { public static final int MAX_BARS = 8; private String color; private int barCount; private int laps;
bpublic GoKart(String color) { this.color = color; }
public String getColor() { return color; } public void charge() { barCount = MAX_BARS; }
public boolean isBatteryEmpty() { return barCount == 0; }
public boolean isFullyCharged() { return MAX_BARS == barCount; }
public void drive(int lapsDriven) { laps += lapsDriven; barCount -= lapsDriven;
} public void drive() { drive(1); }
}

9,359 PointsThe advantage of calling the drive(1) method inside this drive() method, is that you only have to provide the logic for this method once: inside of the drive method that takes an argument.
So now you can simply call the drive() method (without an argument) to make the kart drive a single lap.
drive(); // --> Make the kart drive a single lap
drive(int lapsDriven); // --> Make the kart drive a different (specific) number of laps
