Don't know whats wrong. tried different methods and it's still wrong.

Create a new method named drive that accepts no arguments. It should call the newer drive method passing in a 1 for the default.

GoKart.java
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;
  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }
  public void charge() {
    barCount = MAX_BARS;
  }

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

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

  public void drive() {
    lapsDriven++;
    barCount--;
  }
  public void drive(int laps) {
  lapsDriven += lapsDriven;
   barCount -= barCount;
    public void drive (int lapsGone) {
lapsDriven += lapsGone;
barCount -= MAX_BARS;

Try updating the drive() method to take one int parameter and remember to modify the code so that you add and subtract the amount in the parameter.

When you've done that, create a new method that is also named drive that calls on the old drive method with the argument 1. In Java you can have methods with the same name as long as they take different parameters.

public void testMethod() { // first method
// does something
}

public void testMethod(int x) { // second method
// does something
}

testMethod(); // Will call on first method
testMethod(1); // Will call on second method

Hope this answer helps you in solving your task, if not, feel free to ask again in this thread.
