595 PointsI cant figure out how to set isFullyCharged method to true if charge is full.
I'm really lost here, i cant figure out to have this method return true when charge is equal to max_bars.
public class GoKart {
public static final int MAX_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_BARS;
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount = MAX_BARS;
}
}

What you are doing here is setting the value of mBarsCount. You want to test if it is equal instead.

public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public void charge() {
mBarsCount = MAX_BARS;
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}
Not sure of what is expected but I assume the method you mean is isFullyCharged(). so if mBarsCount has the same value as MAX_BARS then it is fully charged

That is the only thing you need to change - adding an extra equals sign will make it a test for equality, returning a true or false. Remember that the single equals sign is the assignment operator, not a test operator.
