Java Java Objects (Retired) Harnessing the Power of Objects Methods and Constants

These GoKarts have a single rechargeable battery that have a display of bars to measure its energy level. Each battery

where am i going wrong

GoKart.java
public class GoKart {
    public static final int MAX_B = 8;
public final int mBarsCount;
  private String mColor;

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

  public String voidColor() {
    return mColor;
  } 
   public void battery() {
   final int mBarsCount = MAX_B;
 }
}

Task 1:

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

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

  public String getColor() {
    return mColor;
  } 
}

Task 2:

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

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

  public String getColor() {
    return mColor;
  } 
}

Task 3:

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

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

  public void charge() {
    mBarsCount = MAX_BARS;
  } 

  public String getColor() {
    return mColor;
  } 
}

This should work, but if not, please post back.

Thanks!!

thank you so much.GREAT help indeed,i had been stuck for a while but finally got it now.thanks a million.

Always happy to help!

Okay, so let's use our new isFullyCharged helper method to change our implementation details of the charge method. Let's make it so it will only charge until the battery reports being fully charged.

Let's use the ! symbol and a while loop. Inside the loop increment mBarsCount. Please may you help me on this one,stuck for daez.

What challenge is this on?

ITS ON INCREMENTING.JAVA OBJECTS

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

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

  public String getColor() {
    return mColor;
  }

  public void charge() {
    mBarsCount = MAX_ENERGY_BARS;
  //while mBarsCount isn't at 8,
    while(! isFullyCharged()) {
  //charge the GoKart (remember NOT to put a space after mBarsCount).
      mBarsCount++;
    }
  }

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

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

}
