3,615 PointsCan anyone explain to me further how to use while loop and provide examples?
I really can't figure out how to add while loop. (newbie here)
public boolean charging() { boolean isCharging = false; if (!isFullyCharged()) { mBarsCount++; isCharging = true; } return isCharging; }
Need help please (I'm pretty sure my code is wrong xD )
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 charging() {
boolean isCharging = false;
if (!isFullyCharged()) {
mBarsCount++;
isCharging = true;
}
return isCharging;
}
public void charge() {
mBarsCount = MAX_ENERGY_BARS;
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
}

4,615 Pointstwo hints
1) the correct signature of the method is public void charge(); 2) you have to charge (mBarsCount++) until the kart is not fully charged
