Program is not getting terminated

[somashaker goud]

Below is my code which is working fine but it's not getting terminate.

package com.hackersrank;

//Imports
import java.awt.FileDialog;
import java.awt.Frame;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;

public class Distribution {

  public static void main(String[] args) {
       
      Frame f = new Frame();
       
      // Decide Where to read the file from.
      FileDialog foBox = new FileDialog(f,"What File are you looking for?", FileDialog.LOAD);
      foBox.setVisible(true);
       
      //Get the absolute path to the file
      String foName = foBox.getFile();
      String dirPath = foBox.getDirectory();
       
      //Create a file instance for the absolute path.
      File inFile = new File(dirPath + foName);
      BufferedReader in = null;
      Scanner scan=null;
      int sum = 0;
      try{
          //Create a BufferReader to use to read in the file.
          in = new BufferedReader(new FileReader(inFile));
          scan = new Scanner(inFile);
          while(scan.hasNext()){
        	  int num = scan.nextInt();
        	  sum = sum+num;
        }
        System.out.println("Sum of numbers in file is "+sum); 
        
       }
      // catch any IOException that occurs
      catch (IOException io)
      {
          System.out.println("An IO Exception occurred");
          io.printStackTrace();
      }
      finally
      {
          try
          {
              in.close();
              System.out.println("helo");
              
          }
          catch (Exception e){}
          
      }

  }
   
     
}

it's not getting terminate.  

Are there any loops that don't end?
Are there any read statements that are blocking waiting for input?

Add some print statements to see where the program's execution is going.

What prints on the console when you execute the program?

So it isn't working fine, unless we have different definitions about "fine".

Would you like to provide more details, like, what were your inputs? (probably file content).

Or maybe just copy/paste output and highlight where it stuck and what you'd expect to happen further?

[somashaker goud]

I am passing input as a file. It's reading data from file and printing required output. Even finally block is getting executed. Below is the output which I am getting.

Sum of numbers in file is 112
helo

After completion of finally block it's not getting terminated

After completion of finally block

Did you add a print statement at the end of the program just before the ending } for the main() method?  Did it print anything?

I think some thread is holding JVM from closing
From the API doc for the Thread class:

The Java Virtual Machine continues to execute threads until either of the following occurs:

The exit method of class Runtime has been called and the security manager has permitted the exit operation to take place.
All threads that are not daemon threads have died, either by returning from the call to the run method
or by throwing an exception that propagates beyond the run method.    

The Java Virtual Machine exits when the only threads running are all daemon threads.

Make sure all the GUI objects have been fully released so any threads associated with them end.

It's definitely the Frame that's hanging on.  Try dispose().

Also, see this:

[somashaker goud]

Yeah, It was due to Frame. It worked after disposing of.  Thanks for your help
