Java Code to create a panel with Textbox, Button and File Upload

Below is the code for a GUI box having textboxes, browse button with file chooser for a file upload.

JButton Browse = new JButton("Browse");
JTextField t1,t2,t3;  
t1=new JTextField("",30);  
t2=new JTextField("",30);  
t3=new JTextField("",20);  

String t1_input = "";
String t2_input = "";
String t3_input ="";
final JFrame frame = new JFrame("Nodes Required");
JPanel panel2 = new JPanel(new GridLayout(4,0));
panel2.setBorder(BorderFactory.createTitledBorder("Example of GUI Panel JAVA"));

panel2.add(new JLabel("Enter name"));
panel2.add(t1);
panel2.add(new JLabel("Enter Age"));
panel2.add(t2);
panel2.add(new JLabel("Choose File"));
panel2.add(Browse);
panel2.add(new JLabel("File Selected is : "));
panel2.add(t3);
frame.setAlwaysOnTop(false);

//listener
Browse.addActionListener(new ActionListener() {
	  public void actionPerformed(ActionEvent e) {
		//fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
		JFileChooser fileChooser = new JFileChooser(FileSystemView.getFileSystemView().getHomeDirectory());
		fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
		fileChooser.setAcceptAllFileFilterUsed(false);
		int rVal = fileChooser.showOpenDialog(null);
		if (rVal == JFileChooser.APPROVE_OPTION) {
			System.out.println("File Selected : "+fileChooser.getSelectedFile().toString());
			t3.setText(fileChooser.getSelectedFile().toString());
		}
	  }
});

int result11 = JOptionPane.showConfirmDialog(frame, panel2, 
		"Demo", JOptionPane.OK_CANCEL_OPTION);

if (result11 == JOptionPane.OK_OPTION) {

	t1_input = t1.getText().toString();						
	t2_input = t2.getText().toString();
	t3_input = t3.getText().toString();
}
if (result11 == JOptionPane.CANCEL_OPTION || result11 == JOptionPane.CLOSED_OPTION) 
{
	System.out.println("User cancelled the operation, Aborting, Please proceed manually : "+new Timestamp(System.currentTimeMillis()));
}
