Question: These GoKarts have a single rechargeable battery that have a display of bars to measure its energy level. Each battery has a maximum of 8 bars.
For this task, let's add a constant field to the class that stores the maximum number of energy bars. Make sure the field cannot be changed and is accessible from the class, not just the instance. Use the naming convention we learned.
public class GoKart { public static final int MAX_B = 8; public final int mBattery; private String mColor;
public GoKart(String color) { mColor = color; }
public String getColor() { return mColor; }
public void battery() { mBattery = MAX_B; }
}
public class GoKart {
public static final int MAX_B = 8;
public final int mBattery;
private String mColor;
public GoKart(String color) {
mColor = color;
}
public String getColor() {
return mColor;
}
public void battery() {
mBattery = MAX_B;
}
}

One thing that I've noticed. Should mBattery
be declared as final
? Try it without the final
keyword - see if that helps.

private int mBattery;
and add inside the constructor mBattery = 0;
then should work

public class GoKart { private String mColor; public static final int MAX_B = 8; private int mBarsCount;
public GoKart(String color) { mColor = color; mBarsCount = 0; } public void charge(){ mBarsCount = MAX_B; }
public String getColor() { return mColor; } }

Courses Plus Student 29,577 PointsThis code worked for me:
public class GoKart { public static final int MAX_BARS = 8; private int mBarsCount; private String mColor;
public GoKart(String color) { mColor = color; mBarsCount = 0; }
public void load() { mBarsCount = MAX_BARS; }
public String getColor() { return mColor; } }
