5,363 PointsIf in the try{kart.drive(x)} the x value was right, like a 5 for example, what would happen?
the code would just go on? if this was a input window that the user could put a value, can i test this value direct in this try/catch test so i can stop errors early? thanks!
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);
} catch (IllegalArgumentExce
}
}
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;
}
}
