What is wrong here?

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 == MAX_BARS) {
return true;
} else {
return false;

Hi Liberty,

You’re missing a couple of curly brackets is all it is... Your isBatteryEmpty() method needs one more closing bracket and so does the isFullyCharged() method. Easily done! You can see that your code is incorrectly indedented in these two methods. That’s sometimes a clue. Also, a quick count of the opening brackets for a method compared to a quick count of the closing brackets, if you ever suspect you might be missing a bracket, is one method for checking for these type of errors. Some IDEs highlight the corresponding bracket if you place the cursor on either an opening or closing bracket.

Anyway, hope that helps.

Happy coding!
