#Problem with netbeans when reading args passed through console

Hello when I try to run my application through netbeans using the configuration in the Run widget my application
doesnt recognize the arg passed as a string to a file, the reason I have to do it this way is cause in the course it was
made explicit that the application should start it through the following manner.

Detected code, here are some useful tools:

Formatted code 
public class InputFile {
  private File_file;
  private BufferedReader_reader;
  private Status_fileStatus;
  public InputFile(String input) throws FileNotFoundException, IOException {
    final File test = new File(input);
    this ._file = new File(input);
    this ._fileStatus = new Status("", statusCode.UNDEFINED);
    this ._fileStatus = this ._isFile();
    if (this ._fileStatus.getStatusCode() == statusCode.INPUTFILEERROR) {
      return ;
    }
    this ._InitializeReader();
  }
  public Status getStatus() {
    return _fileStatus;
  }
  private Status_isFile() {
    Status output;
    //new Status("",statusCode.ERROR);
    String CWD = System.getenv("CWD");
    boolean isFile = _file.isFile();
    if (!isFile) {
      output = new Status(messages.ifem, statusCode.INPUTFILEERROR);
    }
    else {
      output = new Status(messages.ofem, statusCode.OK);
    }
    return output;
  }
  private void _InitializeReader() throws FileNotFoundException, IOException {
    _reader = new BufferedReader(new FileReader(this ._file, Charset.forName("UTF-8")));
  }
  public BufferedReader getReader() {
    return this ._reader;
  }

this is wher eI handle the file

# 
public class Proyecto_1_Diego_Avila {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws Exception{
        // TODO code application logic here
        final int argSize = args.length;
        
        switch(argSize){
            case 1:
                InputFile file = new InputFile(args[0]);
                Tokenizer scanner = new Tokenizer(file);
                scanner.run();
                break;
            default:
                System.out.println(argSize);
                System.out.println(Utilities.mIncorrectProgramInput);
                // do something;
                break;
        }
    }
    
}

this is the entry point

#

this is how im passing the argument to the main method

#

my teachers want my solution to be executed in the following manner

# 
D:\Directory_of_source_code\>java - jar Project.jar "input.py"
#

the issue is when I try to read data, I declare BufferedReader in the InputFile class

#

when I access the reader in another class I get an error telling me that the reader is null

#

weird

#

its working now

#

now I have another question should I open a new thread?

finite tiger
#

If it's unrelated, and maybe you didn't compile again?

vocal pawn
#

it was probably to do with the working directory that was being used

#

the new question is more about the strategy for doing a scanner than anything

#

like I have to do a scanner for python but I think they are also asking for some features of a parser too

#

what im worried the most right now is things to look out for when escaping characters that are nested within subtokens
