import java.awt.*;
import java.awt.event.*;
import java.awt.AWTError;
class AntiVirus extends Frame implements ActionListener
{
Label select;
TextField file;
Button browse;
Button browsefile;
Button cancel;
Button scan;
Panel panel,panel1;
Dimension dimension;
Label l;
AntiVirus()
{
dimension = new Dimension(120,22);
panel = new Panel();
select=new Label("Select");
select.setPreferredSize(dimension);
file=new TextField();
file.setPreferredSize(dimension);
browse=new Button("Browse Folder");
browse.setPreferredSize(dimension);
browsefile=new Button("Browse File");
browsefile.setPreferredSize(dimension);
scan=new Button("Scan");
scan.setPreferredSize(dimension);
scan.addActionListener(this);
cancel=new Button("Exit");
cancel.setPreferredSize(dimension);
panel.add(file);
panel.add(browse);
panel.add(browsefile);
browse.addActionListener(this);
browsefile.addActionListener(this);
panel.add(cancel);
l=new Label();
panel1 = new Panel();
panel.add(scan);


Panel panel2 = new Panel();
l.setPreferredSize(new Dimension(120,100));
panel2.add(l);
Frame frame = new Frame("Container Frame");
frame.add(panel, BorderLayout.NORTH);
frame.add(panel2, BorderLayout.LINE_START);
frame.add(panel1, BorderLayout.CENTER);

frame.setSize(400,400);
frame.setVisible(true);


}
public void actionPerformed(ActionEvent e) {
if (e.getSource() == browse) {
FileDialog fd=new FileDialog(this);
fd.show();
String filename=fd.getDirectory();
//filename=filename+"\\"+fd.getFile();
file.setText(filename);
}
if (e.getSource() == browsefile) {
FileDialog fd=new FileDialog(this);
fd.show();
String filename=fd.getDirectory();
filename=filename+"\\"+fd.getFile();
file.setText(filename);
}
if (e.getSource() == cancel) {
//dispose();
System.exit(0);
}
if (e.getSource() == scan) {
if(file.getText().equals(""))
{

l.setText("Please Browse The File OR Folder");

}
else
{
l.setText("");
String filetoscan=file.getText();
Window d=new Window(this);
d.show();
Scan sc=new Scan(filetoscan);
}
}
}
public static void main(String a[])

};

It's not clear what you want to do.

When you say "I am unable to debug" does that mean that
you have got this code from somewhere and are not able to understand
OR
that you developed this but don't know how to use a tool (IDE) to debug this.

In the later case, you may want to use eclipse to compile and debug the code.
