Java Java Objects (Retired) Harnessing the Power of Objects Throwing Exceptions

Unable to proceed with the exercise

public void drive(int laps) { // Other driving code omitted for clarity purposes int newAmount = mBarsCount-laps; if(mBarsCount<0){ throw new IllegalArgumentException("Not enough bettery remains"); } mBarsCount = newAmount; }

can you please help me with the exercise above? Its keeps on showing "Are you sure you throw IllegalArgumentException if the requested amount of laps would make the battery less than zero? " // Please help

public class GoKart {
  public static final int MAX_BARS = 8;

    mBarsCount = 0;
  }

    return mColor;
  }

    drive(1);
  }

  public void drive(int laps) {

    throw new IllegalArgumentException("Not enough battery remains");
    }
    mBarsCount = newAmount;
  }



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