Methods and Constants

Can somone show me how to do this question? I have been stuck on this question for a while and do not understand how to pass it.

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

  private String mColor;
   private void int mEnergyBars;
 public GoKart(String EnergyBars) {
   mEnergyBars = energyBars;
 }

  public GoKart(String color) {
    mColor = color;

  }

  public String getColor() {
    return mColor;
  } 
}

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

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

  public String getColor() {
    return mColor;
  } 
}

1) private int mEnergyBars; 2) public GoKart(String energyBars) { 3) you have two constructors with a single string argument. Java can't tell these apart.

The missing method is something like

  public void charge(){
    mBarsCount = MAX_BARS;
  }
