1,089 PointsProtecting a Kart.Drive with Illegal Arg Exception
Hi,
Can you kindly assist me on how the "protect" part of my method Kart.Drive comes about?
How can I fix 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");
}
try (
kart.drive(42);
System.out.printf ("Not possible");
)
catch (IllegalArgumentException iae){
System.out.printf ("The error is %s", 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;
}
}

21,422 PointsYou are so close! Take another look at your try block. Remember since it is a block, it should be opened and closed with curly braces rather than parentheses. If you swap those out, you should be able to complete the challenge.
