2,995 PointsCant Understand Challenge
If someone can explain me how to write this challenge i'll really appreciate it, cause i can't understand what is that i'm doing wrong, or if i am doing at least what the challenge asks me for.
public class GoKart {
public static final int MAX_ENERGY_BARS = 8;
private String mColor;
private int mBarsCount;
public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public boolean chargeB() {
boolean wasChargeB = false;
if (!isBatteryEmpty()) {
mBarsCount++;
wasChargeB = true;
}
while (chargeB()) {
System.out.println("Charging!");
}
return wasChargeB;
}
public void charge() {
mBarsCount = MAX_ENERGY_BARS;
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
}

18,175 PointsChallenge asks you to implement a method which adds one bar to your mBarsCount. Your method charge() should check if battery is not fully charged and only after that add one bar to mBarsCount.
