Exception compiler error, cannot find symbol

if (mBarsCount < 1) { throw new illegalArgumentException("Not enough battery remains."); }

Getting a compiler error saying that it cannot find the symbol "illegal Argument Exception" What did I miss to make this work?

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) {
    if (mBarsCount < 1) {
      throw new illegalArgumentException("Not enough battery remains.");
    }
    mBarsCount -= laps;
  }

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

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

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

}

Mistake is very simple - you wrote illegalArgumentException, but you need to write IllegalArgumentException . Change 1st letter to capital :)

Damn, you beat me to it xD
