While creating a method name isFullyCharged() to set the current bar count to the maximum charge, i am getting this ?

// Task two class GoKart { public static final int MAX_BARS = 8; private String color; private int barCount;

public GoKart(String color) { this.color = color; }

public String getColor() { return color; }

public void charge() { barCount = MAX_BARS; } public boolean isBatteryEmpty() { isBatteryReallyEmpty = barCount == 0; return isBatteryReallyEmpty; } public boolean isFullyCharged() { isBatteryFullyCharged = MAX_BARS; return isBatteryFullyCharged; }

// Task one throwing error

GoKart.java 
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }

  public void charge() {
    barCount = MAX_BARS;
  }
  public boolean isBatteryEmpty()
  {
    isBatteryReallyEmpty = barCount == 0;
    return isBatteryReallyEmpty;
  }
  public boolean isFullyCharged()
  {
    isBatteryFullyCharged = MAX_BARS;
    return isBatteryFullyCharged;
}

Hi Varun, the isFullyCharged() method should be returning a boolean value, based on the value of MAX_BARS. If the current barCount is equal too MAX_BARS it should return true otherwise false.

 public boolean isFullyCharged()
{
    boolean isBatteryFullyCharged = barCount == MAX_BARS;
    return isBatteryFullyCharged;
}
