575 Pointsnew drive method that takes an int and passing it a 1 as a default is not working.
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; }
//this bottom method is not working.
public int drive() { return drive == 1; }
public void drive() { lapsDriven++; }
public void drive (int lapsGone) { lapsDriven += lapsGone; barCount -= MAX_BARS; }
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--; } }
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 int drive() {
return drive == 1;
}
public void drive() {
lapsDriven++;
}
public void drive (int lapsGone) {
lapsDriven += lapsGone;
barCount -= MAX_BARS;

230,688 PointsIt looks like you've added three new methods named "drive", but there should only be one new one.
You also probably don't want to subtract MAX_BARS each time, regardless of the laps driven.

575 PointsOf course, another user of the code just wrote and asked "Where'd that drive method go! I loved that method, can you put it back please?" Sigh...Well thanks to method overloading we can pretty easily bring the method back
Create a new method named drive that accepts no arguments. It should call the newer drive method passing in a 1 for the default.
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 void drive (int lapsGone) {
lapsDriven += lapsGone;
barCount -= MAX_BARS;
}
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 int drive() { return drive == 1; } } // Still does not work. I have only used "drive" twice for overlading. //Error : Bummer: 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

575 PointsThanks got it. It should passing parameters sud be drive(1) empty up on the top.
