6,882 PointsPass in parameter of 1 after overload method?
I called the original method but i cant understand why/how to pass in that parameter 1. I thought mBarsCount-- would automatically subtract 1?
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 drive() {
mBarsCount--;
}
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}

the challenge wants you to call the existing drive method that takes the int laps as a parameter.
public void drive() {
// Call the existing "drive(int laps)" method here and pass in the parameter for it to drive 1 lap.
}

public void drive() {
drive(1);
}
Yes, the code "mBarsCount--" would automatically substract and therefor work, but the goal of this exercise is to learn to reuse function/methods instead of implementing similiar logic in different places (makes for example later refactoring easier, ...)
