Could anyone help me pass this challenge. I am not certain what is wrong with the code.

The error message reads that mBars needs to be set private but when i do the error says that mBars needs to private not entire sure. I would appreciate the help

GoKart.java 
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  public int mBars;
  public GoKart(String color) {
    mColor = color;
    mBars = 0;
  }

  public String getColor() {
    return mColor;
  } 
}

Hello Hayden,

You're close on this. I believe they want the variable to be called mBarsCount, just declare that as private when you make it and you already did a good job setting it to 0 in the constructor, so that should sort things out.

Let me know if this doesn't help.

Look at this code for your example to follow. Connecting the challenge questions to the material covered in the lesson may be a good strategy throughout the course:

public class PezDispenser {
  public static final int MAX_PEZ = 12;
  private String mCharacterName;
  private int mPezCount;

  public PezDispenser(String characterName) {
    mCharacterName = characterName;
    mPezCount = 0;
  }

  public void load() {
    mPezCount = MAX_PEZ; 
  }

  public String getCharacterName() {
    return mCharacterName;
  }
}
  • Instead of MAX_PEZ, you are creating MAX_BARS
  • Instead of mPezCount, you are creating mBarsCount
  • Instead of a load method, you are creating a charge method
