Swing input from a textarea

[Rakesh Keerthi]

Actually I have the below cases :

Case1 : "the collection was guaranteed.i'm sure it is"
Case2 : the collection was guaranteed.i'm sure it is
Case2 : the collection was guaranteed...i'm sure it isThese cases i want to reflect using a swing window.Which will accept these cases.

Conditions :

In case1 , since the text is surrounded by "" it should not do anything.

second case, since the data is not surrounded by "", the "." should be highlighted (if the "." is single) in yellow.

In 3rd case sine the "." is preceded or followed by another "." it should be left as it is.

i've tried the below swing code.

import java.awt.Color;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import java.util.Scanner;
    import java.util.logging.Level;
    import java.util.logging.Logger;
    import javax.swing.*;
    import javax.swing.SwingUtilities;
    import javax.swing.text.BadLocationException;
    import javax.swing.text.DefaultHighlighter;
    import javax.swing.text.Highlighter;




    /**

    public class TestPeriodHighlight {
        private JFrame frame;
        private JPanel panel;
        private JTextArea jTextArea;
        private JButton butt;
        private Highlighter hilit=null;
        private  final Highlighter.HighlightPainter painter = new DefaultHighlighter.DefaultHighlightPainter(Color.yellow);
    TestPeriodHighlight () throws BadLocationException
    {
    createGUI();
    process();
    }
    public void process() throws BadLocationException
    {
     hilit = new DefaultHighlighter();
     jTextArea.setHighlighter(hilit);
    Scanner scan=new Scanner(System.in);
        System.out.println("enter some text \n");
        String line= scan.nextLine();
       if(line.contains("\""))
       {
           System.out.println("Notining to do");
           System.exit(0);
       }
        int dot1=  line.indexOf(".");
        int dot2=line.lastIndexOf(".");
        if(dot1==dot2)
        {
           jTextArea.setText(line);
           hilit.addHighlight(dot1,dot1+1, painter);
           frame.setVisible(true);
        }



    }
    public void createGUI()
    {
    butt=new JButton("clear");
    frame=new JFrame();
    frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
    panel=new JPanel();
    jTextArea=new JTextArea(20,20);
    panel.add(jTextArea);
    panel.add(butt);
     butt.addActionListener(new ActionListener() {

                public void actionPerformed(ActionEvent ae) 

                {
                jTextArea.setText("");
                }


              });
    frame.add(panel);
    frame.pack();
    frame.setVisible(false);



    }

    public static void main(String[] args)
    {
    SwingUtilities.invokeLater(new Runnable() {

                public void run() {
                  try
                  {
                        new TestPeriodHighlight();
                    } catch (BadLocationException ex) {
                        Logger.getLogger(TestPeriodHighlight.class.getName()).log(Level.SEVERE, null, ex);
                 }

                }
                }
                );

        }

    }

this code works fine,but, the problem is that the input is taken in the console and the output is shown in a swing window. and i want input to be in a textarea, a button, and clicking it the output should be displayed in second textarea. please refer the below screenshot for reference.

please help me doing this.

Thanks

You need to add the missing GUI components and remove the scanner code.
You will also need to add an ActionListener to the button to get the text from the first text area, process it and display it in the second text area.
