Need help!

Please help me in method overloading topic. Dont know how to get the code correct.

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() {

    drive(4);
    lapsDriven++;
    barCount--;
  }

  public void drive(int laps)
  {
    lapsDriven -= 1;
}

The first part of the challenge asks you to make it possible for a variable number of laps to be driven passed into the drive() method as an argument and modify the code in the method body to reflect that.

This would be accomplished by the following code:

public void drive(int laps) {
    lapsDriven += laps;
    barCount -= laps;
}

The second part of the challenge wants you to create a second drive function which takes no parameters and calls the current drive method supplying a value of 1 in the method body.

This would be accomplished by the following code:

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

Hi Ted,

Thank you for your response. But I could not find out the logic in the code.

lapsDriven = lapsDriven+laps; and barCount = barCount - laps;

It would be great if you can explain me this piece of code.

Thanks!
