How to Make sure that our methode checks the equality of two variables

this Question is from JAVA Object oriented course.

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(){
    if(barCount==0){
    return true;
    }else{
    return false;
    }
  }
    public boolean isFullyCharged()
    {
      if(barCount==0  &&  MAX_BAR==0){
        return false;
      }
     else

you want to know if the bar count is fully charged (has the maximum number of bars) or (barCount == MAX_BAR)

so change your if statement to read...

 public boolean isFullyCharged(){
      if(barCount == MAX_BARS){
        return true;
      }
    return false;
}
