Protect the call to kart.drive by handling the IllegalArgumentException that is thrown when not enough battery remains. Print out the message from the exception to the screen as you catch the exception.
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(0);
} catch (IllegalArgumentException) {
System.out.println("The battery is empty");
}
}
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;
}
}
