Java Java Objects Harnessing the Power of Objects Overload Methods

I do not understand what the task is asking me to do :(

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

In your new drive method, make sure you call the drive method that takes an int. Pass it a 1, since that's the default"

Sorry I'm new at this and I do not understand what it means when it says "passing in a 1 for the default" could you help me?

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() {
  barCount--;
  lapsDriven++;
}
  public void drive(int lapsAmount) {
    barCount -= barAmount;
    lapsDriven += lapsAmount;
  }

}

What it's asking you to do is basically recreate previous method using the new one. What they mean by passing 1 as default is that your previous method only did one lap, so when you recreate it using your new method you should pass in 1 as parameter. You do this by creating method drive without parameters and inside it call drive and put 1 as parameter. Here is how it should look:

public void drive(int laps) {
    lapsDriven+=laps;
    barCount-=laps;
  }
  public void drive(){
    drive(1);
  }

Hope this helps and best of luck on your java journey :D
