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() { if (GoKart.isFullyCharged()) { System.out.println("It is fully charged"); } if (!GoKart.isFullyCharged()) { System.out.println("It is need to be more charging"); }
}
}
what is wrong in this?
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() {
if (GoKart.isFullyCharged()) {
System.out.println("It is fully charged");
}
if (!GoKart.isFullyCharged()) {
System.out.println("It is need to be more charging");
}
}
}

29,567 PointsBasically you need your program to figure out when the battery has been depleted so you need to write code that will prompt when the battery hits zero. It's the same for when it is fully charged. With that being said your code should look like this:
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(){
if(mBarsCount == 0){
return true;
}
else
return false;
}
public boolean isFullyCharged(){
if(mBarsCount == MAX_BARS)
return true;
else
return false;
}
}
