How do you put an if statement inside of a try catch exception? [closed]

Hello I'm working on method that is reading a file and outputting something. My code worked before I put my if statement in the code, I can't seem to figure out the exception part with the if statement inside of it. Any help would be greatly appreciated!

public static void reader(String file, String argument) {
    File myList = new File(file);
    try {
        Scanner in = new Scanner(myList);
        while (in.hasNextLine()) {
            String s = in.nextLine();
            if(myList.equals(argument)){
            System.out.print(s);
            System.out.println();
        }
        else{
            System.out.print("do something");
            }
        in.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
}

}
