Q:

How to use FileInputStream for accessing an input file from another class?

here are the two java classes:
to get the input file:
public class Inputfile {    

public static void main(String[] args) throws Exception  {
    Scanner sc = new Scanner(System.in);
    Scanner input = null;
    boolean isFile = false;
    while (isFile == false){   
        System.out.print("Input file name? ");
        String fileName = sc.next();

        File inputFile = new File(fileName);
        if (inputFile.exists()){
            input = new Scanner(inputFile);
            isFile = true;
        }            
    } 

to parse the input file: 
public class PdfParse {

public static void main(final String[] args) throws Exception  {

Inputfile inputfile = new Inputfile();
 String fileName;
 fileName =  inputfile.toString();      
  FileInputStream inputstream = new FileInputStream(new File("fileName"));

ParseContext pcontext = new ParseContext();
  .........   
  } 

all i get is FileNotfound Exception for filename. 
I tried to using the string name but i couldn't get the string name from inputfile class using getters but i failed. can someone tell me how to do this?
Thanks a ton. 

A:

You can define your getFileName method in your Inputfile class
 public class Inputfile {    

      public static String getFileName() throws Exception  {
        Scanner sc = new Scanner(System.in);
        String fileName = null;
        boolean isFile = false;
        while (!isFile){   
            System.out.print("Input file name? ");
            fileName = sc.next();

            File inputFile = new File(fileName);
            if (inputFile.exists()){
                isFile = true;
            }            
        } 
        return fileName;
    }
}

And then you can use above defined method in main method of PdfParse class
  public class PdfParse {

      public static void main(final String[] args) throws Exception  {

        String fileName = InputFile.getFileName();

        FileInputStream inputstream = new FileInputStream(new File(fileName));

         ParseContext pcontext = new ParseContext();
         .........   
      } 
  }

Hope this helps.
