"Not enough battery"

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() {
    drive(1);
  }

  public void drive(int laps) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }

  public void drive(int lapsNumber) {
    int newNumber = mBarsCount = lapsNumber;
      if (newNumber > MAX_BARS) {
        throw new IllegalArgumentException ("Not enough battery remains");
      }
    mBarsCount = newNumber;

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

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

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

}

This is how your drive method should look. (Replace the current one, you can't have 2 drive methods with the same signature)

  public void drive(int lapsNumber) {
      if (lapsNumber < MAX_BARS) {
        throw new IllegalArgumentException ("Not enough battery remains");
      }
    mBarsCount = lapsNumber;
  }
