I need the correct answer to this question.

Create a new method named drive that accepts no arguments. It should call the newer drive method passing in a 1 for the default.

GoKart.java 
class GoKart { public static final int MAX_BARS = 8; private String color; private int barCount; private int lapsDriven;

public 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 -= laps; 

} 
public void drive()
  {
   drive(1);
  }

You have to add another constructor for the drive method which doesn't return anything (void). In that method using the increment and decrement operator, increment the lapsDriven and decrement the barCount.

I hope these hints may help you to solve the problem.
