There is something wrong with my code, but I don't know what it is. Can somebody help me?

Create a new public method named isBatteryEmpty that returns true if the battery has 0 bars remaining, and false otherwise.

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

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;} 
}

You've got a couple of stray semicolons in places they shouldn't be, and the braces around the code block following the "if" are exchanged (facing the wrong way).

public boolean isBatteryEmpty();{ :point_left: stray semicolon
if (barCount == 0);} :point_left: stray semicolon, brace pointing the wrong way
return true;{ :point_left: brace pointing the wrong way

Thanks for answering my question! I did what you suggested, but I'm still getting it wrong. Would you mind checking my code again? Thanks.

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

Somehow, a new issue sneaked in:

public boolean isBatteryEmpty()} :point_left: brace pointing the wrong way
