Hi! Below is my code. What happens is that the MessageDialog won't appear. It will be stuck in the search for part, where the program asks for a user input. It won't end. So I was wondering, what's wrong with my code.

Thanks in advance. =)

import java.util.*;
import java.io.*;
import javax.swing.JOptionPane;

public class WorkingFiles {
	
	public static void main(String args[]) throws FileNotFoundException {
		// Local variable declarations.
		String file_name, search_text;
		String data_text = "the quick brown fox jumps over the lazy dog.";
		
		// Input instructions to the console.
		System.out.print("Enter filename: ");
		
		// Ask for the file name.
		Scanner s = new Scanner(System.in);
		file_name = s.next();
		
		// Create the text file with filename from the user.
		PrintWriter oFile = new PrintWriter(file_name + ".txt");
		
		// Input for search keyword.
		System.out.print("Search for: ");
		search_text = s.next();
	
		if(data_text.indexOf(search_text) != -1)
			JOptionPane.showMessageDialog(null, "\"" + search_text + "\" found!", "Keyword Found", JOptionPane.INFORMATION_MESSAGE);
		else
			JOptionPane.showMessageDialog(null, "\"" + search_text + "\" not found!", "Keyword Not Found", JOptionPane.ERROR_MESSAGE);
		
		// Close the file.
		oFile.close();
		
		System.exit(0);
	}
}

EDIT: Sorry about the initialization of the search_text. I just forgot to erase that. My teacher told me that even though the progam will stop, chances are there will be times that it won't. [That's what he meant.]

EDIT: Ok, so the code works. The dialog was just behind my IDE. LOL!

Works for me! Are you sure your dialog isn't just behind something?

As a side, some of your program isn't used, such as the initial value of search_text or anything to do with the output file. Also, you don't need the System.exit(0) at the end of main; the program will stop anyway once it gets here.
