Will the drive method at the very bottom have to have a parameter? The task is asking me to set its int value to 1 (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 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(int MAX_BARS ) {
lapsDriven+=MAX_BARS;
barCount-=MAX_BARS;
}
public void drive(){
lapsDriven++;
barCount--;
}
}

Of 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.

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

8,597 PointsFull Question:
Some users of our GoKart class wrote and asked that our drive method accept a parameter to specify how many laps to go, instead of just one. It happens, well hey at least you can practice your addition and subtraction shortcuts.
Modify the drive method to define a parameter of how many laps should be driven. Update the method body to handle the new parameter.
