Java Read Lines from Text File and Output in Reverse order to a Different Text File

I need to read a file that was selected by the user using the JButton. Each line in the file then needs to be converted in Reverse Order to another text file. When that is done the output values of that file need to display in a JTextArea field. I have a good share of the code done and an area to display the names and path on the console. But I can not get the file to read line by line and output in reverse order to the text area field. Can someone help me understand where I am going wrong? Thank you and here is what I have so far:

import java.awt.BorderLayout; import java.awt.FlowLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.*; import javax.swing.JFileChooser; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JButton; import javax.swing.JPanel; import java.io.BufferedReader; import java.io.BufferedWriter;

public class TextFileInput extends JFrame {

private JTextArea textAreaOutput = new JTextArea(20, 80);

//======================================================= constructor
public void TextFileInput() {
    // Create a button to open a file
    JButton openFileButton = new JButton("Open");
    openFileButton.addActionListener(new OpenAction());

    //... Create a "controls" panel with button on it.
    JPanel controls = new JPanel();
    controls.setLayout(new FlowLayout());
    controls.add(openFileButton);

    //... Create the content pane with controls and a textarea.
    JPanel content = new JPanel();
    content.setLayout(new BorderLayout());
    content.add(controls, BorderLayout.NORTH);
    content.add(new JScrollPane(textAreaOutput), BorderLayout.CENTER);

    this.setContentPane(content);
    this.pack();
    this.setTitle("File Input application");
}
