2,139 PointsI have an error that says there is several errors that are on lines of code that don't exist. Please help.
The console says:
symbol: method isBatteryEmpty()
location: variable kart of type GoKart
JavaTester.java:81: error: cannot find symbol
if (!kart.isBatteryEmpty() || kart.isFullyCharged()) {
^
symbol: method isFullyCharged()
location: variable kart of type GoKart
JavaTester.java:85: error: cannot find symbol
kart.charge();
^
symbol: method charge()
location: variable kart of type GoKart
JavaTester.java:86: error: cannot find symbol
if (!kart.isFullyCharged()) {
However, the code it features doesn't exist, and the lines they are on don't exist either.
public class GoKart {
public static final int MAX_ENERGY_BARS = 8;
private String mColor;
private int mBarsCount;
while (goKart.charge()) {
}
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;
}
}

Treehouse TeacherHi there! I suspect that the reason you are seeing this is not an error from your code, but rather errors generated from the piece of code that's testing your code.
However, I can give you some hints here:
- The while loop you are intended to write will go in the
chargemethod. Not at the top of your code. -
System.load()is not needed for this challenge. This is a method used to load in a Java library.
Hope this helps!

Treehouse TeacherI'm sorry that the hints weren't quite enough. Here's the while loop it wants shown in the correct method.
public void charge() {
while(!isFullyCharged()) {
mBarsCount++;
}
}
This method says while the battery is not fully charged, increment the energy bars by one. Hope this helps!
