7,260 PointsWhere am I going wrong?
I just can't seem to find whats wrong with my code
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
kart.drive(42);
}
try {
kart.drive(42);
}
catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage());
}
}
class GoKart {
public static final int MAX_BARS = 8;
private int barCount;
private String color;
private int lapsDriven;
public GoKart(String color) {
this.color = color;
}
public String getColor() {
return color;
}
public void charge() {
barCount = MAX_BARS;
}
public boolean isBatteryEmpty() {
return barCount == 0;
}
public boolean isFullyCharged() {
return MAX_BARS == barCount;
}
public void drive() {
drive(1);
}
public void drive(int laps) {
if (laps > barCount) {
throw new IllegalArgumentException("Not enough battery remains");
}
lapsDriven += laps;
barCount -= laps;
}
}

12,903 PointsThe issue appears to be with lines 8 and 9 in Example.java.
kart.drive(42);
}
Line 8's kart.drive() is out of a try...catch block, so it's not being handled.
You are closing out the main() function before the try...catch block, preventing it from running.
Remove lines 8 and 9, and then add an additional closing curly-brace to the end of the file.
please not ethe two comments added for further clarity.
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
// REMOVE kart.drive(42);
// REMOVE }
try { // try...catch block is now inside of the main() method, and will run.
kart.drive(42);
} catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage());
}
}
} // added curly-brace
