I can't get to work on this problem. It says that I'm not stating if sentence correctly. Please anyone help.
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
if(laps < 0){
try{
mBarsCount -= laps;
}catch(IllegalArgumentException iae){
System.out.printf("Not enough battery remains");
}
}
}
public void charge() {
while (!isFullyCharged()) {
mBarsCount++;
}
}
public boolean isBatteryEmpty() {
return mBarsCount == 0;
}
public boolean isFullyCharged() {
return mBarsCount == MAX_BARS;
}
}

Full Stack JavaScript Techdegree Graduate 35,467 PointsHello, it looks like you were getting a head of yourself, you don't need to catch anything in this step. Just throwing a new exception, however if your if block you actually want the > "greater than symbol" to check and see if laps is greater than mBarsCount.
Hope this helps.
if (laps > mBarsCount) {
throw new IllegalArgumentException("Not enough battery remains");
}
mBarsCount -= laps;
