How do I return an input stream from a text file

Question

Suppose there's a class with methods..
one of the methods is something like..
public int value() and has a return statement at the end obviously for returning an int value..
Another method reads a text file and creates an input stream..
Scanner data  = new Scanner(new File(input.next()));
I want to return the data when I do a call to this method, but I'm not sure what the method heading would look like..

Are we supposed to magically know what those errors are? Do you think that copying and pasting the exact error messages and indicating the lines they occur on would be useful to us?Sorry about that..
I've replicated the same code below; and put the number of the line where the error is.
+cannot find symbol variable read     [line 21]+
+cannot find symbol variable read     [line 23]+
+cannot find symbol variable read     [line 29]+
+cannot find symbol variable read     [line 31]+
+cannot find symbol variable inputStream     [line 44]+
+calculate() in textInput cannot be applied to (java.util.Scanner)     [line 57]+
the reason I have the _______ for the createInputStream() method is because I'm not really sure what the heading type should be to return the input stream.
import java.io.*;
import java.util.*;
public class textInput
          public void requestFileName()
               Scanner input = new Scanner(System.in);
               System.out.print("Enter file name: ");
          public _______ createInputStream() throws FileNotFoundException
               Scanner input = new Scanner(System.in);
               Scanner read = new Scanner(new File(input.next()));
               return read;
          public void calculate() throws IOException
21           double max;
               double min;
23            int count = 0;
               double total = 0;
               if (read.hasNextDouble())
                    double temp = read.nextDouble();
29                 max = temp;
                    min = temp;
31                 count++
                    total += temp;
                    while (read.hasNextDouble())
                         double current = read.nextDouble();
                         count++;
                         min = Math.min(current, min);
                         max = Math.max(current, max);
                         total += current;
               System.out.println("Max of: " + max);
               System.out.println("Min of: " + min);
44            System.out.println("Average of " + total/count);
          public void close() throws IOException
               inputStream.close();
          public static void main(String[] args)
               textInput run = new textInput();
               try
57                 run.requestFileName();
                    run.createInputStream();
                    run.calculate();
                    run.close();
               catch(FileNotFoundException e)
                    System.out.println("File not found.");
                    System.exit(0);
               catch(IOException e)
                    System.out.prinln("File not found.");
                    System.exit(0);
}
