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

HELP!!

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

}

Whats wrong in this

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

}

Hi Ruthvik,

you need some modifications inside the charge method (not isFullyCharged()) .

The charge method should increment the mBarsCount as long the battery is not fully charged. So you can define a condition for a while loop using the isFullyCharge() method like this:

public void charge() {
   while (!isFullyCharged()) {
// while the return type of isFullyCharged() is not true
// it means while not (!) fully charged

    mBarsCount++;
// increment the mBarsCount
   }
  }

Does it make sense?

Let me know if you are still stuck.
