Courses Plus Student 110 PointsCan't detect where I am going wrong in this code ?
In this code we have to throw an IlllegalArgumentException from the drive method, if the requested number of laps cannot be completed on the current battery level . Make the Exception message"Not enough battery remains".
public class GoKart {
public static final int MAX_BARS = 8;
private String mColor;
private int mBarsCount;
public GoKart(String color) {
mColor = color;
mBarsCount = 0;
}
public String getColor() {
return mColor;
}
public void drive() {
drive(1);
}
public void drive(int laps) {
// Other driving code omitted for clarity purposes
mBarsCount -= laps;
if(laps!=MAX_BARS)
{
throw new IllegalArgumentException;
System.out.println("Not enough battery remains");
}
}
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}

public void drive(int laps) {
// Other driving code omitted for clarity purposes
if (mBarsCount - laps < 0) {
throw new IllegalArgumentException();
} else {
mBarsCount -= laps;
}
}
