1,342 PointsI don't understand what the question is asking. where do I place the method isFullyCharged?
do I need a while and an if statement and where should it be placed?
Is a return statement required?
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;
}
}

public void charge(){
//Look are how isFullyCharged is a method that returns a boolean value
while(!isFullyCharged())
{
mBarsCount++;
}
}

To answer your question about isFullyCharged, it is a method, and not a variable. Variables get declared at the top. Methods (or functions) do work on variables, and often return a result. The result can be a value like "true" or "false", so calling a method that returns a result gives you a similar value to calling a variable that holds a value.
Please let me know if that was helpful. :)

1,342 PointsOh, I see. Thanks, that really helps. Can you tell me why isFullyCharged doesn't have to be declared at the top like I've seen other booleans (e.g. private boolean isFullyCharged or isBatteryEmpty)?
