Hi Thomas,

public class GoKart {
// your fields are perfect
// no need to worry about
  public static final int MAX_BARS = 8;
  private int mBarsCount;
  private String mColor;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0; // <<<<<<<<<<<< initialize mBarsCount to 0 inside the constructor;
  }

  public String getColor() {
    return mColor;
  } 

// here we need to create a charge() method that
// increments mBarsCount to MAX_BARS (8)
// this method returns no value, so it is void
  public void charge() {

// so mBarsCount is equals to your constant variable 
// you declared in the Task 1
  mBarsCount = MAX_BARS;
  }
}

Your code:

// I think here you are trying to create a constructor
// the name of the constructor must be the same as of the class (GoKart, not mColor)
  public mColor(String color) {
    mColor = color;
  }

  public mBars(String MAX_BARS) {
// this should be in the constructor
// no need to create a new method 
// and give it a parameter MAX_BARS
    mBarsCount = 0; 
  }

I hope I could help a little bit
