I couldn't get the answer for this exception handling code. Can someone please help.
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.println("This is a test");
} catch (IllegalArgumentException ae) {
System.out.println("This is also a test code");
System.out.println("The Error was %s", ae.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;
}
}
