Try/catch blocks and if statements in rainfall-averaging program

I am coding a rainfall averaging program. The program lets the user input a file name and if the file cannot be found, then the user is prompted to reenter the file name. The user gets 4 tries before the application quits without processing the data, and the application itself is a rainfall averaging program like I said.

package experiment8;
import java.io.*; 
import java.util.Scanner; 
public class Exceptions
{
  static  Scanner inFile;
  public static void main(String[] args) throws IOException
  {
    int fileTry = 0;
    String fileName;
    Scanner inName = new Scanner(System.in);
    System.out.println("Enter file name>");
    fileName = inName.nextLine();
    boolean fileOk;
    do
    {
      fileOk =  false;
      try
        {

          Scanner scan = new Scanner (System.in);
          Scanner file = new Scanner(new File("inData.dat"));
          fileOk = true;
        }
        catch(FileNotFoundException error)
        {

          System.out.println("Reenter file name>");
          fileName = inName.nextLine();
          fileTry++;
        }
    } while (!fileOk && fileTry < 4);
    PrintWriter outFile = new PrintWriter(new FileWriter("outData.dat"));

    if (fileOk && fileTry < 4 )
    {   
        int numDays = 0;
        double average;
        double inches = 0.0;
        double total = 0.0;
        while (inFile.hasNextFloat())
      {
        inches = inFile.nextFloat();
        total = total + inches;
          outFile.println(inches);
          numDays++;
      }

      if (numDays == 0) 
        System.out.println("Average cannot be computed " +
                         " for 0 days."); 
      else
      {
        average = total / numDays;
        outFile.println("The average rainfall over " +  
          numDays + " days is " + average); 
      }
      inFile.close();
    }
    else

      System.out.println("Error");
    outFile.close();
  }
}

I am trying to code this program so when I input the correct file name, "inData.dat", I will get the proper output. However, when I do this, I continue to get prompted to reenter the file name for the next 3 times, after which I get the "Error" message. Is there something wrong with my try/catch blocks or if statements?
