title: jCheckbox to be displayed in textarea
body: <p>I'm experimenting with JCheckBox. What I want is, when I'd check any of them(checkboxes), the text in the checkbox should be displayed in jtextarea.</p>
  
  <p>What I have right now is this:</p>
  
  <pre><code>import java.awt.*;
  import javax.swing.*;
  import java.awt.event.*;
  
  @SuppressWarnings("serial")
  public class CheckboxSample extends JFrame implements ActionListener{
  
      //vars
      JCheckBox cb1, cb2, cb3, cb4, cb5, cb6;
      JTextArea ta;
      String text = "";
      JLabel lbl;
  
      CheckboxSample(){
  
          Container c = getContentPane();
          c.setBackground(Color.BLACK);
          c.setLayout( new FlowLayout() );
  
          ta = new JTextArea( 10, 20 );
  
          //create two check boxes
          cb1 = new JCheckBox( "Java" );
          cb2 = new JCheckBox( "C#" );
          cb3 = new JCheckBox( "VB.Net" );
          cb4 = new JCheckBox( "Python" );
          cb5 = new JCheckBox( "C++" );
          cb6 = new JCheckBox( "Objective-C" );
  
          lbl = new JLabel( "Choose your favorite programming language/s: " );
  
          //add the checkboxes,  textarea to the container
          lbl.setForeground(Color.white);
          c.add( lbl );
          c.add( cb1 );
          c.add( cb2 );
          c.add( cb3 );
          c.add( cb4 );
          c.add( cb5 );
          c.add( cb6 );
          c.add( ta );
          ta.enable(false);
  
          //add action listeners. We need not add listener to text area
          //since the user clicks on the checkboxes or radio buttons only
          cb1.addActionListener(this);
          cb2.addActionListener(this); 
          cb3.addActionListener(this);
          cb4.addActionListener(this);
          cb5.addActionListener(this);
          cb6.addActionListener(this);
  
          //close the frame upon clicking
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  
      }
  
  
  
      @Override
      public void actionPerformed(ActionEvent e) {
          // TODO Auto-generated method stub
          //know which components are selected by user
          if( cb1.getModel().isSelected() ) text+="\nJava";
          if( cb2.getModel().isSelected() ) text+="\nC#";     
          if( cb3.getModel().isSelected() ) text+="\nVB.Net";
          if( cb4.getModel().isSelected() ) text+="\nPython";
          if( cb5.getModel().isSelected() ) text+="\nC++";
          if( cb6.getModel().isSelected() ) text+="\nObjective-C";
          //else text+="\nFemale";
          //display the selected message in text area
          ta.setText(text);
  
          //reset the message to empty string
          text="";
      }
  
  
      public static void main(String args[])
      {
          //create frame
          CheckboxSample cr = new CheckboxSample();
          cr.setTitle("My Samples");
          cr.setSize(500,400);
          cr.setVisible(true);
      }
  
      }
  </code></pre>
  
  <p>How can I do that without concatenating the text of my checkboxes? Thanks.</p>
