Java Java Objects (Retired) Harnessing the Power of Objects Incrementing

I am lost as to the setup on setting up the charging loop given the example of the pez dispenser.

I am not sure how to set this up. I need to write a loop checking the status of mbarscount and if it is equal to 0 or less than MAX_ENERGY_BARS and to increment mBarsCount to equal MAX_ENERGY_BARS if it is less than the constant.

GoKart.java
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;
  }

  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }
  public boolean charging(){
    boolean notcharged = true;
    if (mbars}
  public boolean isFullyCharged() {
    return mBarsCount == MAX_ENERGY_BARS;
  }

}

Hi Eli,

I think the question mentions using a while loop in the (existing) charge method and the isFullyCharged helper method too. Don't create a new method but rewrite the current charge method.

So, you want to loop through and increment mBarsCount while the isFullyCharged method returns false.

Something like:

while(!isFullyCharged()){
  mBarsCount++; 
}

I hope that works, I'm not at my computer now to check it!

Steve.

Well, just as you added a pez until the dispenser equaled the max, you need to have a for loop add a Bar (mBarsCount++) while the Bars Count is not equal to its Max. Remember ! = not.
