Whats wrong with this code, please?

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 isBatteryEmpty() { if(barCount == 0) { return true; } if (barCount != 0) { return false; } } }

I can't pass this exercise, please let me know what kind of solution should be provided.

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 isBatteryEmpty() {
    if(barCount == 0) {
      return true;
    }
    if (barCount != 0) {
      return false;
    }
  } 
}

" public isBatteryEmpty() { if(barCount == 0) { return true; } if (barCount != 0) { return false; }"

^this method is not a boolean return type. try adding boolean behind the access modifier and before the method name.

Thank you for answer, I managed to solve this problem by adding boolean to the method name.
