Create a new method named drive that accepts no arguments. It should call the newer drive method passing in a 1 for the default. correct it help me i don't know what's wrong with my program
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() {
lapsDriven++;
barCount--;
}
public void drive(int laps) {
lapsDriven += lapsDriven;
barCount -= barCount;
public void drive() {
drive(1);
//this is the newer drive method,but it's uncorrect.
}
}
}

Treehouse TeacherHi there, Jackie! What Presley means is that you've done something like this:
public void myFunction() {
public void myFunction2() {
// some code here
}
}
This is the attempt to declare another function inside a function which is not what they're asking for and actually invalid, I believe. But even if we fix that there are still errors in your code. It seems like you may have changed the original code that passed step 1.
In the drive function that takes a number of laps, we want to add the number of laps we're going to drive to the number of laps already driven. Let's say our GoKart has driven 10 laps. Your code adds the number of laps already driven to itself. It will double every time it's run.
lapsDriven += lapsDriven; //This adds the current count 10 to the current count resulting in 20
But let's say we want to only drive the GoKart 3 more laps. Then we need to call the drive function and send in 3 laps. So we need to add the number of laps we want to drive to the number already driven.
lapsDriven += laps; //If we send in 3 as the number of laps and the lapsDriven is currently 10 the new lapsDriven will be 13
Also you have the line drive(1);. And this is correct, but it should be the only line within the drive function that has no parameters.
I think you can get it with these tips, but let me know if you're still stuck!
