Looking for a little clarity on this challenge! (GoKart challenge and the part dealing with signatures)

I am not sure I am understanding what the question is asking for. I will admit I am a little overwhelmed with all the new terminology that is being used in this section.

GoKart.java 
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 drive(){
   1;

  }

  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }

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

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

}

the method signature on the second drive method is okay. The options for method body is to call the first drive method, or perform the decrement ( something like mBarsCount--; or mBarsCount -= 1; at a guess)

see

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;
  }
  //HERE
  public void drive(){
      drive(1);  //JUST CALLS THE OTHER DRIVE METHOD
  }
  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }

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

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

}

Thanks for the help. At least I know I was on the right track... Thanks again!
