I cant add this method

Question

I cant add another drive method when another method named drive already exists. Please help

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

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

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

}

Hey Josh,

at the end of this challenge you should have two different drive() methods. Your first drive() takes an integer "laps" as parameter. Your second drive() method that you should create takes no parameters and this is the difference between them.

drive(int laps) vs. drive()

The funny thing is that you can use the preexisting drive() method inside your newly created drive() method. BUT don´t forget to pass arguments inside how many laps you plan to cruise.

So the code can look like this:

public void drive () { //new drive method without any arguments
   drive(1); // preexisting method thet take the number of laps you want to drive
  }

You can add another drive method as long as it has a different argument list. That's what method overloading is about.
