1,365 PointsOkay, so let's use our new isFullyCharged helper method to change our implementation details of the charge method.
i'm getting the error message "reached end of file while parsing". how can i fix it?
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() {
while (!isFullyCharged()) {
mBarsCount++;
}
}

mBarsCount = MAX_ENERGY_BARS;
/*You must assign the value of bars count to MAX_ENERGY_BARS
in order to prove that it is fully charged
and exit the loop. This will check within the isFullyCharged() method
and prove it to be true,
thus the != true portion is false and you can
exit your while loop. */

public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
}

return mBarsCount == 0;

public boolean isFullyCharged() {

_ }_
}

You needed one more curly bracket where the underscores are.
Sorry couldn't figure out how to put it in the code block style.

Treehouse TeacherIf you do 3 backticks followed by the word java and then close with 3 backticks it will format properly.

7,515 PointsThis is what I have listed, I'm incrementing mBarsCount in the while loop, I'm returning mBarsCount equal to MAX_ENERGY_BARS, I'm implementing a while loop and I have all of my closing braces- what am I missing?
Craig Dennis
Treehouse TeacherisFullyCharged is used to check if the battery is fully charged, it shouldn't actually charge the battery. That is the job of the method named charge. You should loop in the charge method checking to see if the battery is not isFullyCharged.
That make more sense?

while(mBarsCount != MAX_ENERGY_BARS()) {

return mBarsCount == MAX_ENERGY_BARS;

7,515 PointsI think this possibly fits?
Sean McKeown
23,267 PointsI think I just coded isFullyCharged like this:
public boolean isFullyCharged() {
return mBarsCount == MAX_ENERGY_BARS;
}
Hope that helps
