Question

This is my code:
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;
  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }
  public String getColor() {
    return mColor;
  }
  public void drive(int laps) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }
  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }
  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }
  public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }
}
This is my challange: 
I have added a method drive that defines a parameter laps. These high-powered GoKarts use 1 energy bar off their battery each lap.
Using method signatures, add a new method called drive that performs just 1 lap and takes no arguments.
I do not know how to do that, i tried adding this:   
public void drive() {
    drive(laps = 1);
  }
but that does not work.
Can I get help with understanding what to do?

The problem is how you try to pass the the laps argument to the method, you don't pass arguments by specifying the name and then the value, you simply type the value and that's all, the code should look like this:
csharp
public void drive() 
{ 
  drive(1); 
}

Since 1 is the first argument you pass it will automatically be assigned to the first parameter of the method.
If there is still something that confuses you then feel free to ask me follow up questions, I'll do my best to clear things up for you.
