}
Garage g = new Garage(10);
PrintWriter pw = new PrintWriter(new FileWriter(args[1]));//this is line 35
BufferedReader br = new BufferedReader(new FileReader(args[0]));
String> int lineCount = 1;
while (oneRecord != null) {
String tokens[] = oneRecord.split(" ");
if (tokens.length != 2) {
System.err.println("Invalid record at line(" + lineCount + "): "" + oneRecord + """);
}
String license = tokens[0];
boolean arrival = tokens[1].equals("ARRIVE");
if (arrival) {
pw.print(oneRecord);
pw.print(": ");
boolean didArrive = g.arrive(license);
if (didArrive) {
pw.println("parked");
} else {

}
} else {

pw.print(": ");
Car c = g.depart(license);
if (c == null) {
pw.println("not in the garage");
} else {
pw.println("departs after having moved " + c.getNumberOfMoves() + " time(s).");
}
}
> lineCount++;
}
pw.flush();
this is the error i get:
Unable to create : Garage.txt
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1

Explanation / Answer
your error is coming at the line that you pointed out: PrintWriter pw = new PrintWriter(new FileWriter(args[1]));//this is line 35 because args doesn't contain two arguments. The code that you pasted has two instances of the args check, so I'm doubting that you tested against the source that you pasted. Please be sure that you're rebuilding and calling the correct code. The troubling part about the second args check (where you have the try/catch) is that you catch the exception, print an error, and continue. This seems like a fatal error which should end with a System.exit or a return call. Hope this helps.
