1,121 PointsMethod Signature help
I am having trouble understanding how method signatures work. I could use an answer as to how to complete this exercise and just general pointers on understanding method signatures.
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;
}
}

23,733 PointsSince you already have a drive() method that accepts and int just call it and pass 1 to it:
public void drive(){
drive(1);
}
