Question

In the following code ,how can I access text in the textfield(i.e object x in the following code) in the place of z in the following code:
BufferedReader br=new BufferedReader(new InputStreamReader(new FileInputStream(z)));
import java.awt.Color;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import java.util.*;
import javax.swing.JTextArea;
public class TextAreaTest1
public static void main(String[] args)
TextAreaFrame frame = new TextAreaFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
A frame with a text area and buttons for text editing
class TextAreaFrame extends JFrame implements ActionListener
public String TextAreaFrame()
setTitle("TextAreaTest");
setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);
Container contentPane=getContentPane();
contentPane.setLayout(new GridLayout(5,5,0,0));
buttonPanel = new JPanel();
JPanel textField=new JPanel();
buttonPanel.add(new JLabel("enter"));
// add button to append text into the text area
JTextField x=new JTextField(20);
JButton insertButton = new JButton("Insert");
textField.add(new JLabel("Enter the path"));
// textArea = new JTextArea(8, 30);
// contentPane.add(insertButton);
buttonPanel.add(insertButton);
textField.add(x);
String z=x.getText();
insertButton.addActionListener(this);
contentPane.add(textField);
JPanel group=new JPanel();
          final JTextField a=new JTextField(18);
          JRadioButton b1=new JRadioButton("Start");

Answer 1

1) Swing related questions should be posted in the Swing forum.
2) Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.
3) Use a more descriptive variable name. "x" means nothing.
4) Define the text field reference name as a class variable, not a local variable.
