Java naming file

I'm trying to rename the file that my program is outputting, but no matter what name i'm trying to change it to, it is stuck with the first name i listed which is "output.txt". I rename it to output1. txt and it still gives me output.txt could someone help with this?

public class Assignment2 {

public static void main(String[] args) {

    if (args.length < 1) {
        System.out.println("Sample command: java Assignment2 input.txt");
        System.exit(0);
    }
    try {
        Scanner scanner = new Scanner(new File(args[0]));
        FileWriter fw = new FileWriter("output1.txt");
        int i = 1;

        while (scanner.hasNext()) {
            System.out.println("Matrix #" + i);
            processMatrix(scanner, fw);
            i++;
            System.out.println("");
            fw.write(System.lineSeparator());  
        }

        scanner.close();
        fw.close();
    } catch (FileNotFoundException ex) {
        System.out.println(ex.getMessage());
    } catch (IOException ex) {
        Logger.getLogger(Assignment2.class.getName()).log(Level.SEVERE, null, ex);
    }

}

From what I can see there is nothing wrong with your code.

So the only problem I can think of, is you are not building/compiling the file and therefore you are stuck on a older version of that file.

I don't know what technology stack you are using, but a still way to check this since its java, hopefully you got the environment variables configures. Just go to your terminal, to the file folder and:

javac Assignment2.java java Assignment2

You can also tell me which IDE you are using, or how you are building/running your code.
