3,969 PointsHELP - Java Objects - Incrementing and Decrementing - Challenge!
The challenge goes like this:
"Okay, so let's use our new isFullyCharged helper method to change our implementation details of the charge method. Let's make it so it will only charge until the battery reports being fully charged. Let's use the ! symbol and a while loop. Inside the loop increment mBarsCount."
I have seen the previous video 5 times but I'm still stuck.. :-(
Can anyone help me?
My while loop is:
while(!isFullyCharged()) { mBarsCount++; }
Apparently its not correct.. :-)
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 void charge() {
mBarsCount = MAX_ENERGY_BARS;
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
while(!isFullyCharged()) {
mBarsCount++;
}
}

13,725 PointsYou need to implement your loop inside the charge() method:
public void charge() {
while(!isFullyCharged()) {
mBarsCount++;
}
}

public void charge(){ while(!isFullyCharged()){ mBarsCount++; } }
