Errors implementing into the charge method.

./GoKart.java:35: error: reached end of file while parsing } ^ ./GoKart.java:32: error: cannot find symbol while (isBatteryEmpty.charge()){ ^ symbol: variable isBatteryEmpty location: class GoKart 2 errors

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() {
    boolean charge = false; 
    if (!isBatteryEmpty()){
       mBarsCount++;
       charge = false;
    }
    {
    return mBarsCount == MAX_ENERGY_BARS;
  }
    while (isBatteryEmpty.charge()){
    }

}

Hi bryce,

your thinking process is too advanced :)

The isFullyCharged method is nice, no need to change it. Inside the charge method, you can use isFullyCharged method to write a condition for a while loop.

The while loop condition should say: While the battery is NOT fully charged increment mBarsCount.

 public void charge() {
    while (!isFullyCharged()) {
// use the isFullyCharged() to write the condition
    mBarsCount++;
    }
  }

Make sense?

Perfect thank you I believe i misunderstood writing conditions inside of methods.. as well as how helper methods can be used to create conditions inside of while loops. Believe the saying keep is simple stupid comes into play again. Thanks Grigorij.
