Java Java Objects (Retired) Harnessing the Power of Objects Method Signatures

I suck at Java,what is wrong now?

I made it drive 1 lap, what is wrong now.

GoKart.java
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public String getColor() {
    return mColor;
  }

  public void drive(int laps) {
    // Other driving code omitted for clarity purposes

        mBarsCount -= laps;
  }

   GoKart.drive(1);

  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }

  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }

  public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }

}

Hi damir,

create a new drive method and inside that method call the old drive method.

Like this:

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