Having some problem with FileDialog

[vamsi naki]

Hi ,
I wrote a porgam where there is a textarea and two buttons ,one to load files into the textarea and other button to save what is written in the text area.
I have two problems though
1)The methods filedialog.getDirectory(),filedialog.getFile() return nulll so i am not able to load any file in the text area
2)When i try to save a file ,i used filedialog.setDirectory("C:"+"\" ") and filedialog.setFile("untitled.txt").The problem is it doesnt show the c:\ as the default directory when the dialog box opens .

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class button3 {
  public static void main(String[]args)
  {
	  test t=new test();
	  t.go();
  }
}
class test
{JFrame frame =new JFrame();
JTextArea area=new JTextArea(10,20);
	void go()
	{
		
		JButton button1=new JButton("open");
		JButton button2=new JButton("save");
		
		JScrollPane scroller=new JScrollPane(area);
		scroller.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
		frame.setVisible(true);
		frame.setSize(500, 500);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setLayout(new FlowLayout());
		button1.addActionListener(new ActionListener()
		    {
			
			 public void actionPerformed(ActionEvent evt)
			  {
				FileDialog filedialog=new FileDialog(new Frame(),"Load",FileDialog.LOAD);
				
				String name=filedialog.getDirectory()+filedialog.getFile();
				try {
					System.out.println(name);
					BufferedReader myreader=new BufferedReader(new FileReader(name));
					try {
						while(myreader.readLine()!=null)
						{
							area.setText(myreader.readLine());
						}
					} catch (IOException e) {
						
						e.printStackTrace();
					}
			
				} catch (FileNotFoundException e) {
					
					e.printStackTrace();
				}
				
				filedialog.setTitle("Load & Save");
				filedialog.setVisible(true);
				
			  }
		
	    	
		   }
		);
		button2.addActionListener(new ActionListener()
	    {
		
		 public void actionPerformed(ActionEvent evt)
		  {
			FileDialog filedialog=new FileDialog(new Frame(),"Save",FileDialog.SAVE);
			filedialog.setDirectory("C:"+"\" ");
			filedialog.setFile("untitled.txt");
			try {
				BufferedWriter mywriter=new BufferedWriter(new FileWriter("untitled.txt"));
				mywriter.write(area.getText());
				mywriter.flush();
				mywriter.close();
			
			} catch (IOException e) {
				
				e.printStackTrace();
			}
			filedialog.setTitle("Load & Save");
			filedialog.setVisible(true);
			
		  }
	
    	
	   }
	);
		
		frame.add(button1);
		frame.add(button2);	
		frame.add(scroller);
	}
		
	}

In other words, you set the directory to this string:

C:"

But you really wanted this string, right?

C:\

So you've just got your Java string escaping rules a bit mixed up. You need this code:

filedialog.setDirectory("C:\\")
