i did it the same way for the first task but not working

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


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

  public String getColor() {
    return color;
  }

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

  public boolean isFullyCharged(){
 if (barCount == 0){

 public boolean isBatteryEmpty(){
 if (barCount ==0){ 
   return true;} That is one } too many
   }
   if(!barCount == 0){ //you can't say !barCount when barCount is an int
     return false;} // That is one } too many
   }
 }
 //Same mistakes in this method as above
  public boolean isFullyCharged(){
 if (barCount == 0){
   return true;}
   if(!barCount == 0){ 
     return false;} 
 }
}

These function can be written like this instead:

public boolean isBatteryEmpty(){
    return barCount == 0
}

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