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

Why won't my loop work ?

I thought you have to make sure the battery isn't fully charged so you do the !. then increment mBarsCount

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 isFullyCharged() {
    while (!isFullyCharged () ){
      mBarsCount +1;
    }
    return mBarsCount == MAX_ENERGY_BARS;
  }

Hi there,

You have put the code to charge the Kart in the isFullyCharged method. It should be in charge.

Make sense?

  public void charge() {    
    while (!isFullyCharged()){
      mBarsCount++;
    }
  }

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

Steve.

Thank you, it makes sense, if the battery isn't fully charged then charge it by + 1 until it is fully charged

Absolutely, yes. The isFullyCharged() helper method is fine as it is.
