JAVA HELP! my code compiles but there is still an error?

}
// *****MAIN METHOD*****
public static void main(String[] args){

try {

newStock.buy();
} catch (NumberFormatException e) {
System.out.println("Error");
return;
}
}
else if (i.toUpperCase().contains("SELL")) {

newStock.sell();
} catch (NumberFormatException e) {
System.out.println("Error");
return;
}
} else {
System.out.println("Error - input does not contain buy/sell");
}
} System.out.println(nf.format(getTotal()));
}
}
this program compiles but when i enter transaction sequence which is either buy/sell an error follows it
the error would be :
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
